Summary: We have developed a nanoplatform capable of improving the immunosuppressive tumor microenvironment (TME) by actively targeting it. By camouflaging the surface of gold nanorods (GNRs) with myeloid-derived suppressor cells (MDSCs) membrane, we have achieved targeted adjustment of the TME. This nanoplatform also enables multimodal cancer imaging and dual immunotherapy.

Summary: In this research, zinc-doped silver telluride quantum dots with excellent fluorescence performance and stability were synthesized for near-infrared-IIb fluorescence imaging. Zinc doping improved the fluorescence properties and lifetime of the quantum dots, and enhanced their colloidal stability. PEGylated zinc-doped silver telluride quantum dots achieved high-resolution imaging of cerebral blood vessels and could be used to monitor brain condition after traumatic brain injury.

Summary: In this study, zinc-doped silver telluride quantum dots (Zn:Ag2Te QDs) with bright fluorescence in the near-infrared-IIb (NIR-IIb) window were synthesized. The introduction of Zn dopants improved the quantum yield and fluorescence lifetime by inhibiting crystal defects and reducing non-radiative transitions. Additionally, Zn-doping enhanced the colloidal stability of Zn:Ag2Te QDs by increasing the number of ligands on their surface. The PEGylated Zn:Ag2Te QDs with high absolute quantum yield enabled noninvasive imaging of the cerebral vasculature in mice, allowing for the monitoring of brain conditions after traumatic brain injury.

Summary: Perovskite LEDs with exceptional performance at high brightness have been achieved by introducing a multifunctional molecule that removes non-radiative regions and suppresses luminescence quenching at the interface. These LEDs show a peak EQE of 23.8% at 33 mA cm(-2) and retain EQEs more than 10% at high current densities of up to 1,000 mA cm(-2). An operational half-lifetime of 32 h at high brightness has been achieved, representing the best stability for perovskite LEDs.

Summary: This work presents a general and efficient method to synthesize pH-responsive near-infrared (NIR) emitting gold nanoclusters by introducing aliphatic tertiary amine (TA) groups as ligands. The pH-responsive NIR emission is achieved through the protonation and deprotonation of TA groups, which induce electronic structure changes. The pH-responsive gold nanoclusters can serve as specific and sensitive probes for lysosomes in cells, offering non-invasive emissions without interference from intracellular autofluorescence.

Summary: In this study, a multifunctional molecule, tetrabutylammonium dihydrogen phosphate (TDP), was introduced to enhance the emission efficiency of quasi-2D perovskite. TDP effectively suppressed low-order phases, passivated defects, and increased the exciton binding energy of the perovskite, resulting in improved radiative recombination and high emission efficiency. The TDP-incorporated perovskite films exhibited significantly higher photoluminescence quantum yield, external quantum efficiency, and brightness.

Summary: Researchers have synthesized a highly bright near-infrared chemiluminophore through molecular engineering of the electron-withdrawing group. This chemiluminophore shows a 3 to 5-fold higher quantum yield compared to existing ones. By combining it with a cathepsin B-responsive moiety, an activatable chemiluminescence probe has been developed for real-time detection of deeply buried tumor tissues and accurate chemiluminescence-guided laparotomy in living mice.

Summary: Metal-phenolic network-functionalized nanoparticles (t-P@TFP NPs) are designed to combat multidrug resistance (MDR) and metastasis in cancer by reshaping the tumor microenvironment from insensitive to sensitive. These NPs trigger a near-infrared laser-activated multistage reaction, releasing perfluoropentane (PFP) and hyperthermia to efficiently kill cancer cells. Furthermore, they inhibit ATP-dependent drug efflux and induce immunogenic cell death (ICD) to improve sensitivity to chemotherapeutic agents and evoke antitumor immunogenicity.

Summary: This study investigates the wrapping mechanism of chimeric single-stranded DNA (ssDNA) on CdSe-ZnS quantum dots (QDs) with different ratios of phosphorothioate (PS) modification. Results show that 3-mercaptopropionic acid (MPA) and O-(2-mercaptoethyl)-O-methyl-hexa (ethylene glycol) (mPEG) reduce the binding affinity of ssDNA through electrostatic repulsion and steric exclusion. Both simulation and experiment demonstrate that larger QD size brings ssDNA closer to the QD surface. The effect of the PS base ratio on ssDNA conformation is also revealed.

Summary: In this study, biomimetic aggregation-induced emission (AIE) photothermal agents with hitchhiking ability (DC@BPBBT dots) were developed by coating the nanoaggregates of the NIR AIE polymeric photothermal agents with dendritic cell (DC) membranes. The DC@BPBBT dots can be hitchhiked on endogenous T cells, leading to enhanced tumor delivery efficiency. Additionally, these dots were found to activate T cells to secrete TNF-alpha, effectively reducing the expression of HSP70 and rendering tumor cells more sensitive to heat.

Summary: Low-temperature photothermal therapy (PTT) is a promising therapeutic strategy, but the expression of heat shock proteins (HSPs) can hinder its efficacy. Researchers have developed a smart nanobomb that can explode in the tumor microenvironment and release carbon monoxide (CO) to inhibit the expression of HSPs, thereby improving the effectiveness of low-temperature PTT.

Summary: This study presents a general synthetic approach to control the 3D spatial relationships between quantum dots and other non-nucleic-acid molecules using highly programmable wireframe DNA origami structures. By understanding the relationship between chimeric single-stranded DNA length and quantum dot size, single quantum dots were integrated into DNA origami structures and arbitrary 3D spatial relationships between quantum dots and dyes were programmed. This approach enables the fabrication of hybrid materials for functional nanoscale photonic devices.

Summary: A novel fluorescent probe, PM, was successfully synthesized and designed for the colorimetric fluorescent detection of Hg2+ in aqueous THF solution. The sensing mechanism of PM involves the metal ion-induced hydrolysis of the Schiff-base skeleton, which was confirmed by various experiments and calculations. A portable smartphone-assisted platform was established for the convenient and reliable Hg2+ detection. PM was also applied to monitor intracellular Hg2+ ions and has the potential for developing specific chemoprobes for Hg2+ detection in sulfur-rich living organisms.
