Abstract :
The hypoxic microenvironment and radioresistance of tumor cells, as well as the delay in efficacy evaluation, significantly limit the effect of clinical radiotherapy. Therefore, developing effective radiosensitizers with monitoring of tumor response is of great significance for precise radiotherapy. Herein, a novel radiosensitizer (term as: SCuFs) is developed, consisting of traditional Chinese medicine (TCM) compounds salidroside, Cu2+, and hydroxyl radical (center dot OH) activated second near-infrared window fluorescence (NIR-II FL) molecules, which make the radiosensitization effect and boosted chemodynamic therapy (CDT) efficacy. The overexpressed glutathione in the tumor induces the SCuFs dissociation, allowing deep penetration of the drug to the whole tumor region. After X-ray irradiation, salidroside inhibits the Nuclear factor erythroid 2-like 2 (Nrf2)protein expression and blocks cells in the G2/M phase with the highest radiosensitivity, which amplifies the reactive oxygen species (ROS) generation to exacerbate DNA damage, thus achieving radiosensitization. Meanwhile, the upregulated ROS provides sufficient chemical fuel for Cu+-mediated CDT to produce more center dot OH. NIR-II FL imaging can monitor the center dot OH changes during the therapy process, confirming the radiosensitization effect and CDT process related to center dot OH. This study not only achieves effective radiosensitization and cascaded ROS-mediated CDT efficacy, but also provides a useful tool for monitoring therapeutic efficacy, showing great prospects for clinical application.

Abstract :
Metformin (MET) is currently the first-line treatment for type 2 diabetes mellitus (T2DM). However, overdose and long-term use of MET may induce a serious liver injury. What's worse, diagnosis of MET-induced liver injury remains challenging in clinic. Although several probes have been reported for imaging MET-induced liver injury utilizing upregulated hepatic H2S as a biomarker, they are still at risk of nonspecific activation in complex physiological environments and rely on light excitation with limited imaging depth. Herein, we rationally designed and developed a dual-locked probe, DPA-H2S, for precise imaging of MET-induced liver injury by H2S-activated sonoafterglow luminescence. DPA-H2S is a small molecule consisting of a sonosensitizer protoporphyrin IX (PpIX) and an afterglow substrate that is dual-locked with a H2S-responsive 2,4-dinitrobenzene group and a O-1(2)-responsive electron-rich double bond. When employing DPA-H2S for imaging of MET-induced liver injury in vivo, since the PpIX moiety can produce (1)O(2)in situ at the liver site under focused ultrasound (US) irradiation, the two locks of DPA-H2S can be specifically activated by the highly upregulated H2S at the liver injury sites and the in situ generated O-1(2), respectively. Thus, the sonoafterglow signal of DPA-H2S is significantly turned on, enabling precise imaging of the MET-induced liver injury. In vitro results showed that, through H2S-activated sonoafterglow luminescence, DPA-H2S was capable of imaging H2S with good sensitivity and high selectivity and realized deep tissue imaging (similar to 20 mm, signal-to-background ratio (SBR) = 3.4). Furthermore, we successfully applied DPA-H2S for precise in vivo imaging of MET-induced liver injury. We anticipate that our dual-locked probe, DPA-H2S, may serve as a promising tool in assisting the diagnosis of MET-induced liver injury in clinics and informing the clinical utilization of MET in the near future.

Abstract :
Real-time monitoring the therapeutic process of sonodynamic therapy (SDT) is essential to optimize the treatment course in time and eventually improve the efficacy. The generation of singlet oxygen (1O2) is a quintessential characteristic of SDT, which permits non-invasive monitoring of SDT by real-time imaging of 1O2 inside the tumor. Nonetheless, the majority of probes are unable to measure 1O2 in real time because of its short half-life and strong oxidative capacity. Here, the study constructs a ratiometric nanoplatform (DTPI) utilizing two fluorescent probes and the sonosensitizer TiO2. The poisonous 1O2 generated by DTPI following ultrasonic (US) radiation efficiently destroys tumor cells. The structural disruption of fluorescent dye IR-1061 by 1O2 leads to a reduction in the DTPI fluorescence signal at 1100 nm, while US radiation has no impact on the fluorescence signal at 1550 nm. Thus, DTPI provides a precise and consistent reflection of the treatment efficacy at the tumor site, leveraging the ratiometric fluorescence signal and variations in oxygen content throughout the treatment process. This ratiometric-fluorescence-based reflection strategy establishes an effective and dependable platform for the real-time monitoring and assessment of the cancer therapeutic effect through ratiometric probes. The study develops a novel second near-infrared (NIR-II) ratiometric fluorescent nanoplatform for real-time monitoring and evaluating cancer sonodynamic therapy efficacy in vivo. image

Abstract :
MicroRNA-21 (MiR-21) has been confirmed to be upregulated in tumors, and its abnormal expression is closely associated with tumor occurrence. However, the traditional imaging methods are limited to qualitative imaging of miR-21, and no effective strategy has been developed for monitoring its concentration in vivo during cancer initiation and progression. Herein, a biosensor is created utilizing a NIR-II ratiometric fluorescent nanoprobe to quantitatively monitor dynamic alterations in miR-21 levels in vivo. The nanoprobe (termed DCNP@DNA2@IR806) is constructed by introducing IR806 as a donor and down-conversion nanoparticles (DCNP) as the acceptor, using DNA as linkers. Upon miR-21-responsive initiation of the nanoprobe, the 1550 nm fluorescent signal of DCNP stimulated by a 808 nm laser (F1550, 808Ex) increased because of the close proximity of IR806 to the DCNP and the subsequent non-radiative energy transfer (NRET). Meanwhile, the 1550 nm fluorescent signal of DCNP stimulated by a 980 nm laser (F1550, 980Ex) remained stable because of the absence of NRET. This ratiometric NIR-II fluorescent signal has been confirmed to be a reliable indicator of miR-21 concentration in vivo. The strategy holds promise for further enhancing the understanding of microRNAs-based molecular mechanisms underlying cancer progression, laying a foundation for the early diagnosis of microRNAs-related diseases. A miR-21-activated ratiometric NIR-II fluorescence nanoprobe (DCNP@DNA2@IR806) for early diagnosis and real-time monitoring of miR-21 levels during cancer initiation and progression via enhanced ratiometric fluorescence signals in vivo. The content of activated miR-21 is positively correlated with tumor volume in the development of tumors. image

Abstract :
The abnormal fluctuation of temperature in vivo usually reflects the progression of inflammatory diseases. Noninvasive, real-time, and accurate monitoring and imaging of temperature variation in vivo is advantageous for guiding the early diagnosis and treatment of disease, but it remains difficult to achieve. Herein, we developed a temperature-activated near-infrared-II fluorescence (NIR-II FL) and surface-enhanced Raman scattering (SERS) nanoprobe for long-term monitoring of temperature changes in rat arthritis and timely assessment of the status of osteoarthritis. The thermosensitive polymer bearing NIR-II FL dye was grafted onto the surface of nanoporous core-satellite gold nanostructures to form the nanoprobe, wherein the nanoprobe contains NIR-II FL and Raman reference signals that are independent of temperature change. The ratiometric FL1150/FL1550 and S-1528/S-2226 values of the nanoprobe exhibited a reversible conversion with temperature changes. The nanoprobe accurately distinguishes the temperature variations in the inflamed joint versus the normal joint in vivo by ratiometric FL and SERS imaging, allowing for an accurate diagnosis of inflammation. Meanwhile, it can continuously monitor fluctuations in temperature over an extended period during the onset and treatment of inflammation. The tested temperature change trend could be used as an indicator for early diagnosis of inflammation and real-time evaluation of therapeutic effects.

Abstract :
Over the past few decades, pretargeted bioimaging has made significant contributions to disease diagnosis and the real-time visualization of biological processes. Notably, the inverse electron demand Diels-Alder (IEDDA) reaction between tetrazine (Tz) and trans-cyclooctene (TCO) has shown enormous potential in pretargeted bioimaging applications by capitalizing on its rapid kinetics, specific reactivity, biorthogonality and biocompatibility. To date, imaging probes based on the Tz-TCO click reaction have been extensively developed and widely used for pretargeted bioimaging applications. In this review, we focus on the Tz-TCO click reaction and summarize its applications in pretargeted bioimaging. Firstly, the fundamental principles for designing imaging probes based on the Tz-TCO click reaction are explained. Then, recent advances in imaging probes based on the Tz-TCO click reaction are discussed in detail. Finally, the current challenges and perspectives of the Tz-TCO click reaction in pretargeted bioimaging applications are presented. The Tz-TCO click reaction-based pretargeting bioimaging strategy involves two steps: (1) Enrichment of the first bioorthogonal component (Tz/TCO moiety) at targets of interest (TOI) by using a functional group-modified Tz/TCO moiety; (2) addition of the second bioorthogonal component (TCO/Tz motif) for the in situ Tz-TCO click reaction, which is accompanied by the acquisition of imaging signal at TOI.image

Abstract :
Plasmonic nanoparticles and their assemblies have been widely used in biosensing, optical imaging, and biomedicine over the past few decades. Especially in the field of radiotherapy, the physicochemical prop-erties of high-Z plasmonic nanomaterials endow them with the ability to sensitize radiotherapy. Compared with single particles, the assembled structure with tunable properties leads to versatile appli-cations in drug delivery and cancer treatment. In this review, we focus on plasmonic nanoparticles and their assemblies for cancer radiotherapy. First, the sensitization mechanism of plasmonic radiosensitizers is briefly introduced. Subsequently, the recent progress in cancer radiotherapy is systematically discussed according to the structure and shape classification. Finally, the current challenges and future perspectives in this field are also discussed in detail.(c) 2023 Elsevier B.V. All rights reserved.

Abstract :
Accurately quantifying microRNA levels in vivo is of great importance for cancer staging and prognosis. However, the low abundance of microRNAs and interference from the complex tumor microenvironment usually limit the real-time quantification of microRNAs in vivo. Herein, for the first time, we develop an ultrasensitive microRNA (miR)-21 activated ratiometric nanoprobe for quantification of the miR-21 concentration in vivo without signal amplification as well as dynamic tracking of its distribution. The core-satellite nanoprobe by miR-21 triggered in situ self-assembly was built on nanogapped gold nanoparticles (AuNNP probe) and gold nanoparticles (AuNP probe). The AuNP probe generated a photoacoustic (PA) signal and ratiometric SERS signal with the variation of miR-21, whereas the AuNNP probe served as an internal standard, enabling ratiometric SERS imaging of miR-21. The absolute concentration of miR-21 in MCF-7 tumor-bearing mice was quantified to be 83.8 +/- 24.6 pM via PA and ratiometric SERS imaging. Our strategy provides a powerful approach for the quantitative detection of microRNAs in vivo, providing a reference for the clinical treatment of cancer.

Abstract :
Real-time imaging of reactive oxygen species (ROS) during cisplatin chemotherapy of cancer is imperative to fully reveal their functions in the biological response to cisplatin. Currently, using a bioluminescent probe for real-time imaging of a specific ROS in vivo during cisplatin chemotherapy has not been achieved. Herein, three bioluminescent probes, F Probe, N Probe and P Probe were synthesized for real-time imaging of the primary ROS, O-2(center dot-). They all consisted of a bioluminescent emitter (D)-luciferin ((D)-LH2) and an O-2(center dot-)-recognition group, and their bioluminescent signal could be turned on in response to O-2(center dot-). In vitro results indicated that P Probe was the most suitable one among the three probes for detection of O-2(center dot-), with high sensitivity, excellent selectivity and stability. P Probe was then successfully applied for real-time imaging of O-2(center dot-) in both cancer cells and tumors during cisplatin chemotherapy. The imaging results demonstrated that O-2(center dot-) amount in cancer cells increased with the increasing dose of cisplatin, and that cisplatin-induced upregulation of O-2(center dot-) level in cancer cells was upstream of the cancer-killing pathway of cisplatin. We envision that P Probe may serve as an elucidative tool to further explore the role of O-2(center dot-) in cisplatin chemotherapy.

Abstract :
Optical imaging in the second near-infrared (NIR-II, 900-1700 nm) window has been extensively investigated for bioimaging. However, a strong autofluorescence background from real-time excitation light significantly reduces the images' quality of NIR-II fluorescence (FL) imaging. To resolve this issue, a NIR-II self-luminous small molecule (CLPD) based on bioluminescence (BL) resonance energy transfer (BRET) mechanism is first developed. The reactive oxygen species (ROS) can trigger NIR-II BL and reduce the NIR-II FL signals of the CLPD simultaneously, enabling ROS-correlated ratiometric BL/FL imaging. CLPD is used for high-contrast NIR-II BL imaging of osteoarthritis as well as guiding the treatment process by ratiometric BL/FL imaging. Moreover, CLPD is applied for NIR-II BL imaging of tumor triggered by the generated ROS during PDT. A correlation between the ratiometric NIR-II BL/FL signal and tumor size is constructed, providing a trustworthy tool for early assessment of PDT effect. Overall, this study presents a novel NIR-II self-luminous small molecular probe for in vivo imaging and provides a strategy for design a self-evaluation system of therapeutic effect.
