Summary: Undoped and manganese-doped ZnS nanocrystals encapsulated with thioglycolic acid were synthesized and tested for the photodegradation of methyl orange in aqueous solution. The presence of manganese doping was found to decrease the photocatalytic degradation efficiency. ZnS nanocrystals showed better efficiency than doped nanocrystals under UV irradiation. ZnS-TGA nanocrystals achieved a dye degradation efficiency of 81.37% after 6 minutes, indicating their potential as a low-cost and environmentally friendly material for water pollution treatment via photodegradation.

Summary: A novel sensor PVA capped Mn doped ZnS incorporated MoS2 nanosheet composite modified gold electrode (PVA-Mn:ZnS/MoS2@GE) was developed for the determination of acebutolol (ACB). Cyclic voltammetry (CV) and square wave voltammetry (SWV) were used to measure the electrochemical performance of ACB. The nanocomposite PVA-Mn:ZnS/MoS2 showed improved electrochemical current sensitivity compared to bare gold electrode when used as a modifier in electrode-based sensors. The SWV technique in pH 7.0 phosphate buffer was used to monitor biological, environmental, and tablet samples spiked with ACB, with a limit of detection of 0.38 x 10(-9) M and a limit of quantification of 1.28 x 10(-9) M.

Summary: The study demonstrates that nuclease digestion results in almost complete liberation of 2-AP mononucleotides, independent of labeling site and neighboring bases. Additionally, nuclease digestion can lead to increased sensitivity through higher numbers of 2-AP labeling, which is not achievable in traditional sensors without full liberation of 2-AP.

Summary: Biofilms, which are accumulated microorganisms, cause persistent bacterial infection and drug resistance. Photodynamic inactivation (PDI) is a promising treatment for bacterial infections, but biofilms pose challenges for photosensitizers' reactive oxygen species (ROS) generation efficiency. Researchers proposed a universal three-in-one matrix of Ge-ADP assembly to enhance ROS generation and successfully eliminate bacterial biofilms.

Summary: In this study, a strategy of conjugating chitosan with halo-fluorescein was proposed to enhance the photostability and pH inertness of the dye. The cross-linking and hydrogen-bonding of chitosan protected the encapsulated halo-fluoresceins from photobleaching and prevented intramolecular spirocyclization, resulting in significantly improved stability and pH insensitivity. The CS-halofluoresceins showed great potential for aerobic photoredox synthesis, photodynamic bacteria inactivation, and light-assisted preservation of perishable fruits.

Summary: Artificial photosynthesis is important for renewable energy generation, sustainable development, and environmental protection. Dye-protein hybrids have potential for photosynthesis mimics, but their performances are limited due to incompatibility between dye and protein matrix. This study proposes that increasing the dye-protein compatibility can enhance the photo-biocatalytic performance, demonstrated by ThTPD-insulin amyloid assembly. ThTPD exhibits improved light absorption and longer excited state lifetime, leading to enhanced efficiency in biocatalytic solar-to-chemical conversion.
