Abstract :

Resveratrol (Res) is a natural polyphenol exhibiting anti-oxidant and anti-inflammatory activity. However, the applications of Res have been limited due to its low stability and water solubility. To enhance the bioaccessibility of Res, unfolding bovine serum albumin-modified selenium nanoparticles (UBSA@SeNPs) encapsulated within chitosan (CS)-coated Pickering emulsions (CS-UBSA@SeNPs-PE) were used to load Res. The results showed that Res-loaded CS(0.06 %)-UBSA@SeNPs-PE has small droplet size (16.13 μm), high gel properties and excellent antioxidant properties. During the simulated digestion process, CS reduced the release rate of Res from Res-loaded CS(0.06 %)-UBSA@SeNPs-PE (42.27 %) to reach a slow release effect. Importantly, Res could quickly release from CS-UBSA@SeNPs-PE within intestinal fluid or in the presence of chitosanase. In simulated absorption experiments, the intestinal permeability of Res in Res-loaded CS(0.06 %)-UBSA@SeNPs-PE were enhanced by 292.31 % compare to Res-loaded CS(0 %)-UBSA@SeNPs-PE. In pharmacokinetic studies, Res-loaded CS(0.06 %)-UBSA@SeNPs-PE had an area under the curve (AUC) up to 3467.99 ± 127.43 ng*h/mL. Furthermore, CS also improved the mucoadhesive nature of UBSA@SeNPs-PE, resulting in a gut-retention time of Res-loaded CS(0.06 %)-UBSA@SeNPs-PE that reached up to 60 h. In conclusion, CS-UBSA@SeNPs-PE can serve as an effective oral delivery system for improving the bioaccessibility of Res. © 2024 Elsevier B.V.

Abstract :

For malignant tumor phototherapy, current biomolecules-based materials face challenges such as limited tissue penetration, insufficient tumor accumulation, and overlook of the unique benefits of chirality, thus hampering their phototherapeutic efficiency. Herein, we introduce a novel near-infrared circularly polarized (NIR-CP) light-responsive hybrid CuInSe2@ZnS (CISe@ZnS) quantum dots (QDs) hydrogel (QDs@L/D-Gel), which showcases distinctive NIR chiroptical activity, highly enhanced tumor retention, and superior photothermal/photodynamic properties. Particularly, the QDs@L-Gel exhibits a prominently improved photothermal conversion efficiency (PCE) of 43 % and elevated reactive oxygen species (ROS) upon 808-nm CP light irradiation, outperforming those of linearly polarized light directly emitted from a laser device. Moreover, a remarkably enhanced phototherapeutic efficacy (tumor inhibition rate = 83 %) can be achieved for QDs@L-Gel treated mice after 808-nm CP light treatment, without any toxic side effects. Our findings highlight the importance of supramolecular chirality in NIR-CP-mediated phototherapy, thereby paving a new avenue for more advanced and effective tumor treatment in clinical applications. © 2024 Elsevier Ltd

NIR-Light-Triggered Mild-Temperature Hyperthermia to Overcome the Cascade Cisplatin Resistance for Improved Resistant Tumor Therapy SCIE

Abstract&Keyword Cite Version(3)

Abstract :

Currently, cisplatin resistance has been recognized as a multistep cascade process for its clinical chemotherapy failure. Hitherto, it remains challenging to develop a feasible and promising strategy to overcome the cascade drug resistance (CDR) issue for achieving fundamentally improved chemotherapeutic efficacy. Herein, a novel self-assembled nanoagent is proposed, which is constructed by Pt(IV) prodrug, cyanine dye (cypate), and gadolinium ion (Gd3+), for systematically conquering the cisplatin resistance by employing near-infrared (NIR) light activated mild-temperature hyperthermia in tumor targets. The proposed nanoagents exhibit high photostability, GSH/H+-responsive dissociation, preferable photothermal conversion, and enhanced cellular uptake performance. In particular, upon 785-nm NIR light irradiation, the generated mild temperature of approximate to 43 degrees C overtly improves the cell membrane permeability and drug uptake, accelerates the disruption of intracellular redox balance, and apparently enhances the formation of Pt-DNA adducts, thereby effectively overcoming the CDR issue and achieves highly improved therapeutic efficacy for cisplatin-resistant tumor ablation. A novel self-assembled nanoagent (Cy-Pt@HA NP) is developed to conquer the cascade drug resistance (CDR) issue of cisplatin. The proposed nanoagent presents NIR light-triggered mild hyperthermia, superior cellular uptake, and tumor-microenvironment-responsive dissociation for effective ablation of drug-resistant tumors, thereby opening a new avenue for addressing CDR issue and maximizing the platinum-based therapeutic efficacy for cancer treatment.image

Abstract :

Currently,enzyme-responsive nanomaterials have shown great promise in prognosis or diagnosis of disease biomarker.However,the great obstacle for conventional enzyme-responsive nanomaterials frequently lies in autofluorescence interference,poor monodispersity,uncontrollable size and morphology,low optical stability,and biotoxicity,which fundamentally impede their practical application in biological systems.To overcome these deficiencies,we proposed a novel strategy for reliable and precise detection of an enzyme disease biomarker,alkaline phosphatase(ALP),through lanthanide(Ln3+)nucleotide nanoparticles(LNNPs)with extremely improved monodispersity and uniformity,which were achieved by the coordination self-assembly between ATP and Ln3+inside micellar nanoreactor.Specifically,for ATP-Ce/Tb LNNPs,highly improved photoluminescence(PL)emission of Tb3+can be achieved via efficient Ce3+sensitization.We demonstrated that ALP could specifically cleave the phosphorus-oxygen(P-O)bonds of ATP and result in the collapse of ATP-Ce/Tb scaffold,finally leading to the PL quenching of Tb3+.By taking advantage of time-resolved(TR)PL technique,the fabricated ATP-Ce/Tb LNNPs presented superior selectivity and sensitivity for the ALP bioassay in complicated serum samples,thus revealing the great potential of ATP-Ce/Tb LNNPs in the areas of ALP-related disease prognosis and diagnosis.

Abstract :

Recently, chiral inorganic nanomaterials have attracted considerable interest for their chiroptical property and chirality-dependent phototherapeutic performance. Herein, for the first time, we propose a near-infrared circularly polarized light (NIR-CPL) responsive supramolecular hydrogels with high ground state chirality (| gabs| up to 3.2 x 10-2) and intense upconverted circularly polarized luminescence activity (|glum| up to 2.6 x 10-2) for tumor photodynamic therapy. After supramolecular co-assembly, methylene blue loaded lanthanide upconversion nanoparticles (UCMBs) are effectively attached to the helical nanofibers constructed by amino acid precursors, which can achieve NIR-CPL triggered reactive oxygen species (ROS) production. The obtained hybrid hydrogels exhibit efficient NIR light conversion, improved photodynamic performance and efficient tumor inhibition. These findings provide a new perspective for exploring NIR-CPL responsive upconversion materials with outstanding chirality-dependent phototherapy characteristic and efficient therapeutic outcomes for further biomedical application.

Abstract :

Wound infections hinder the healing process and potentially result in life-threatening complications, which urgently require rapid and timely detection and treatment pathogens during the early stages of infection. Here, an intelligent wound dressing was developed to enable in situ detection and elimination of pathogenic bacteria through a combination of point-of-care testing and antibacterial photodynamic therapy technology. The dressing is an injectable hydrogel composed of carboxymethyl chitosan and oxidized sodium alginate, with addition of 4-methylumphulone beta-D-glucoside (MUG) and up-converted nanoparticles coated with titanium dioxide (UCNPs@TiO2). The presence of bacteria can be visually detected by monitoring the blue fluorescence of 4-methylumbellione, generated through the reaction between MUG and the pathogen-associated enzyme. The UCNPs@TiO2 photosensitizers were synthesized and demonstrated high antibacterial activity through the generation of reactive oxygen species when exposed to near-infrared irradiation. Meanwhile, a smartphone-based portable detection system equipped with a self-developed Android app was constructed for in situ detection of pathogens in mere seconds, detecting as few as 103 colony-forming unit. Additionally, the dressing was tested in a rat infected wound model and showed good antibacterial activity and pro-healing ability. These results suggest that the proposed intelligent wound dressing has potential for use in the diagnosis and management of wound infections. Statement of significance An intelligent wound dressing has been prepared for simultaneous in situ detection and elimination of pathogenic bacteria. The presence of bacteria can be visually detected by tracking the blue fluorescence of the dressing. Moreover, a smartphone-based detection system was constructed to detect and diagnose pathogenic bacteria before reaching the infection limit. Meanwhile, the dressing was able to effectively eliminate key pathogenic bacteria on demand through antibacterial photodynamic therapy under NIR irradiation. The proposed intelligent wound dressing enables timely detection and treatment of infectious pathogens at an early stage, which is beneficial for wound management. (c) 2023 Acta Materialia Inc.

Abstract :

Stimuli-responsive nanoagents, which simultaneously satisfy normal tissue clearance and tumor-specific responsive treatment, are highly attractive for precise cancer theranostics. Herein, we develop a unique template-induced self-assembly strategy for the exquisitely controlled synthesis of self-assembled lanthanide (Ln(3+)) nucleotide nanoparticles (LNNPs) with amorphous structure and tunable size from sub-5 nm to 105 nm. By virtue of the low-temperature (10 K) and high-resolution spectroscopy, the local site symmetry of Ln(3+) in LNNPs is unraveled for the first time. The proposed LNNPs are further demonstrated to possess the ability for highly efficient loading and tumor-microenvironment-responsive release of doxorubicin. Particularly, sub-5 nm LNNPs not only exhibit excellent biocompatibility and predominant renal-clearance performance, but also enable efficient tumor retention. These findings reveal the great potential of LNNPs as a new generation of therapeutic platform to overcome the dilemma between efficient therapy and long-term toxicity of nanoagents for future clinical applications.
