In this study, a novel "OFF-ON" fluorescent probe MPZ ((E)-5-((10-ethyl-2-methoxy-10H-phenothiazin-3-yl)methylene)thiazolidine-2,4-dione) based on phenothiazine is synthesized, which can rapidly (7 s) detect biogenic amines (BAs) through deprotonation, utilizing both colorimetric and fluorescent dual channels. An app for visual portable detection of fish freshness, named "Visual Evaluation", is independently developed. This app integrates several functions, including image capture, editable scanning of red, green, and blue (RGB) values, data analysis fitting, data storage, and verification.

Noble metal nanoparticles have attracted tremendous attention as the promising signal reporters for catalytic-colorimetric lateral flow immunoassay (LFIA). However, it remains great challenges for improving their stability and catalytic activity. Herein, first, a kind of porphyrinic based metal-organic framework (MOF) was used as a carrier for loading platinum (Pt) nanoparticles to avoid its aggregation.

Current study investigates the medicinal applications of (Palash), the state flower of Jharkhand, India, focusing on synthesising biomodified copper oxide nanoparticles (CuO-NPs) and its antifungal properties. Flavonoid content in the flower extract was quantified by aluminium chloride colorimetric analysis. CuO-NPs were synthesised via co-precipitation method and then modified with methanolic flower extract.

A new Donor-Acceptor type pyrazinacene derivative (1) featuring strong ICT was synthesized by linking electron-donating triphenylamine (TPA) and electron-accepting CN groups via a pyrazinacene core. The compound exhibits a dramatic color change from greenish blue to red-violet upon selective recognition of naphthalene (3) to form a 1:1 co-crystal (1•3). This color change is induced by intermolecular CT between pyrazinacene and naphthalene's aromatic moieties, driven by π-hole···π interactions.
