Abstract ：
Nanomaterials that engage in well-defined and tunable interactions with proteins are pivotal for the development of advanced applications. Achieving a precise molecular-level understanding of nano-bio interactions is essential for establishing these interactions. However, such an understanding remains challenging and elusive. Here, we identified stoichiometric interactions of water-soluble gold nanoparticles (Au NPs) with bovine serum albumin (BSA), unraveling their synergism in manipulating emission of nano-bio conjugates in the second near-infrared (NIR-II) regime. Using Au25(p-MBS)18 (p-MBS = para-mercaptobenzenesulfonic acid) as paradigm particles, we achieved precise binding of Au NPs to BSA with definitive molar ratios of 1:1 and 2:1, which is unambiguously evidenced by high-resolution mass spectrometry and transmission electron microscopy. Molecular dynamics simulations identified well-defined binding sites, mediated by electrostatic interactions and hydrogen bonds between the p-MBS moieties on the Au25(p-MBS)18 surface and BSA. Particularly, positively charged residues on BSA were found to be pivotal. By careful control of the molar ratio of Au25(p-MBS)18 to BSA, atomically precise [Au25(p-MBS)18] x -BSA conjugates (x = 1 or 2) could be formed. Through a comprehensive spectroscopy study, an electron transfer process and synergistic effect were manifested in the Au25(p-MBS)18-BSA conjugates, leading to drastically enhanced emission in the NIR-II window. This work offers insights into the precise engineering of nanomaterial-protein interactions and opens new avenues for the development of next-generation nano-bio conjugates for nanotheranostics.

Abstract ：
Ultrasmall gold nanoclusters (AuNCs) with photoluminescence in the second near-infrared region (NIR-II) have emerged as promising probes for in vivo biomedical applications. However, it remains a challenge to utilize NIR-II-emitting AuNCs for imaging brain glioblastoma (GBM), which is highly lethal and hard to diagnose in time. Herein, we have presented systematic investigations on the brain delivery and GBM targeting efficacies of NIR-II-emitting AuNCs protected by different ligands. We first synthesized four types of AuNCs with surface coatings of small thiolated ligands and proteins, and then studied their in vitro penetration capability into the blood-brain barrier (BBB) and in vivo GBM targeting performances. It was found that the BBB permeability of AuNCs determined by the in vitro transwell model was not evidently affected by the surface ligands. Significantly, AuNCs protected by albumin exhibited notably extended blood circulation and less skull binding compared to those protected by small ligands, enabling superior in vivo brain GBM-targeted NIR-II PL imaging. We also modified the albumin-AuNCs with targeting peptides to improve in vivo imaging contrast. Additionally, AuNCs had negligible toxic effects on major organs as well as brain tissues and neurons, corroborating their good biocompatibility. This study examined the surface engineering of NIR-II luminescent AuNCs for brain GBM targeting, which may offer insights into the future design of AuNCs for bioapplications.

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

Abstract ：
Mechanofluorochromic materials are a type of 'smart' material because of their adjustable fluorescent properties under external mechanical force, making them significant members of the materials family. However, as the fluorescent characteristics of these materials highly depend on their microstructures, the still insufficiently in-depth research linking molecular structures to light emission motivates researchers to explore the fluorescent properties of these materials under external stimuli. In this work, based on synthetic [AgS4] microplates, we explore a fascinating mechanical-induced photoluminescent enhancement phenomenon. By applying mechanical force to solid-state [AgS4] to damage the surface morphology, a significant enhancement in photoluminescence is observed. Moreover, the emitted intensity increases with the extent of damage, which can be attributed to alterations in crystallinity. This work provides valuable insights into the relationship among photoluminescence, crystallinity, and mechanical force, offering new strategies for designing luminescent devices. © 2024 American Chemical Society.

Abstract ：
Ligand-protected metal nanoclusters (NCs) are ultrasmall particles (<3 nm) that represent the molecular state of metal materials. Owing to their molecule-like structure - particularly their atomic precision and protein-like hierarchy - metal NCs feature numerous useful molecule-like properties, including discrete energy levels, strong luminescence, intrinsic magnetism and programmable catalytic activity. In this Review, by regarding metal NCs as metallic analogues of organic molecules, we summarize methodological and mechanistic advances in their precise synthesis at the molecular and atomic levels. We first decipher cluster structure based on a protein-like hierarchical scheme and discuss synthetic strategies that realize molecular monodispersity in these clusters. We resolve formation mechanisms of metal NCs at the molecular level, aiming to establish step-by-step reaction maps reminiscent of total synthesis routes of organic molecules. We then examine approaches to customize the composition and morphology of the metal core, metal-ligand interface and ligand shell at the atom level. This Review concludes with our perspectives on the future development of atomic precision chemistry in both metal NCs and other inorganic nanomaterials.

Abstract ：
Metal nanoclusters (MNCs) can be synthesized with atomically precise structures and molecule formulae due to the rapid development of nanocluster science in recent decades. The ultrasmall size range (normally < 2 nm) endows MNCs with plenty of molecular-like properties, among which photoluminescent properties have aroused extensive attention. Tracing the research and development processes of luminescent nanoclusters, various photoluminescent analysis and characterization methods play a significant role in elucidating luminescent mechanism and analyzing luminescent properties. In this review, it is aimed to systematically summarize the normally used photoluminescent characterizations in MNCs including basic parameters and methods, such as excitation/emission wavelength, quantum yield, and lifetime. For each key parameter, first its definition and meaning is introduced and then the relevant characterization methods including measuring principles and the revelation of luminescent properties from the collected data are discussed. Then, it is discussed in details how to explore the luminescent mechanism of MNCs and construct NC-based applications based on the measured data. By means of these characterization strategies, the luminescent properties of MNCs and NC-based designs can be explained quantitatively and qualitatively. Hence, this review is expected to provide clear guidance for researchers to characterize luminescent MNCs and better understand the luminescent mechanism from the measured results.

Abstract ：
Gold nanoclusters (AuNCs) are emerging as promising functional probes for bioapplications. However, because of rapid renal clearance, it is a challenge to tailor their biofate and improve their disease-targeting ability in vivo. Herein, we report an efficient strategy to tailor their organotropic actions by rationally designing AuNC assemblies. The nanocluster assembly is established based on the moderate electrostatic interaction or strong coordination between AuNCs, enabled by solely chitosan (CS) or the coadded chelating metal ions (e.g., Gd3+). We show that AuNCs-CS is rapidly excreted into urine, while further coordination of Gd3+ confers assemblies with liver and lung accumulation capabilities, dependent on Gd3+ contents. The organotropic actions are unraveled to result from their tunable stability in vivo and binding capability to cells/proteins. We also demonstrate that lung-targeting assemblies can enable specific NIR-II luminescence imaging of lung orthotopic tumors, which cannot be realized by employing discrete AuNCs. We anticipate that these findings will offer insights into the design principles of metal nanocluster probes and related bioapplications.

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
