Summary: A new strategy combining photodynamic insecticide action and stimulus-responsive polymer micelles has been developed to improve photostability, enhance utilization rate, and reduce pest resistance. The strategy involves the preparation of PBA-modified mPEG conjugate followed by self-assembly to obtain polymeric nanoparticles, which show stability in water but can change structure in response to UV light and/or esterase stimulation. The nanoparticles effectively inhibit the photodegradation of PpIX and exhibit higher phototoxicity to insect cells compared to free PpIX. UV light and/or esterase stimulus can trigger PpIX release, resulting in high photodynamic activity.

Summary: Photodynamic therapy (PDT) is a valuable treatment method for vulvar intraepithelial neoplasia (VIN) as it allows for minimal tissue destruction and treatment of multifocal disease. However, resistance to PDT in vulvar cancer may be due to alterations in the heme synthesis pathway and increased activity of the DNA repair protein APE1. Inhibition of APE1 activity may enhance the efficacy of PDT.

Summary: Microorganisms in skin wounds can cause infections, but photodynamic therapy using porphyrinoids as photosensitizers can effectively eradicate them and promote wound healing. Porphyrinoids have the ability to generate reactive oxygen species, which not only prevent infections but also promote cell proliferation and regulate inflammation factors.

Summary: The interaction between synthetic protoporphyrin IX and protoporphyrin IX extracted from Harderian glands of ssp Rattus novergicus albinus rats with bovine serum albumin was studied. The aggregation and binding properties of protoporphyrin IX were found to be influenced by pH. Protoporphyrin IX has potential applications as a fluorescence probe and photosensitizer.

Summary: The study showed that cationic chlorophyll photosensitizers interact with non-ionic surfactant Tween 80 to form stable molecular complexes, with the PS molecules located at the periphery of surfactant micelles. Additionally, the interaction strength between PS and surfactant increases with the charge of the macrocyclic cation.

Summary: In this study, photoresponsive functions such as photochromism were successfully incorporated into aggregation-induced emission (AIE) molecules through a simple and low-cost strategy. A series of C3-symmetric molecules with aggregation-induced emission and base-gated photochromism were synthesized, showing excellent photophysical characteristics in solid-state. The base-gated photochromism of these molecules, constructed by low-cost benzene rings, can detect toxic organic bases, attributed to the multicyano-sensitized benzene rings of these AIE luminogens.

Summary: In this study, HOFs were formed by self-assembly of TATB and linked with ILu via amide bond to improve the ECL efficiency. The ILu-HOFs NH2-ITO showed a 23.4-fold increase in ECL efficiency compared to ILu alone. A sandwich ECL biosensor was then constructed for the detection of ICP, achieving a broad linear range and low LOD, and successfully detecting ICP in environmental samples.

Summary: This work presents the design and synthesis of six phenolic resins with clusteroluminescence (CL) property. By increasing the number of through-space interactions (TSIs) units and introducing electron-donating/-withdrawing groups, these non-conjugated polymers achieve near-infrared (NIR) emission with high absolute quantum yield. Through experiments and theoretical analysis, the crucial roles of through-space locally excited state and through-space charge transfer state in achieving CL from non-conjugated polymers are revealed.

Summary: Nonconjugated clusteroluminogens (CLgens), such as proteins and polystyrene, have become increasingly important in photophysics due to their advantages over traditional conjugated dyes in biological applications. However, their weak visible emissions in the aggregate state have hindered their development. This study proposes a strategy to construct a higher-level intramolecular through-space interaction (TSI) in multi-aryl-substituted alkanes, resulting in efficient clusteroluminescence (CL) with high luminescence quantum yield and long emission wavelength.

Summary: In this study, the PEC responses were enhanced by about 4.3-fold through in situ electrostatic assembly of [BIm][BF4] on TP-NH2-ITO. Furthermore, [BIm](+)-TP-NH2-ITO exhibited a much larger photocurrent in a water/DMSO binary solvent with a water fraction of 90%, showing a 6.7-fold increase compared to pure DMSO. The PEC detection strategy based on the in situ assembly of [BIm](+)--TP-NH2-ITO and the competitive reaction between magnetic bead linked dsDNA and HCT-116 cells achieved single-cell bioanalysis and early diagnosis of tumors.
