Abstract Water-dispersible perovskite nanocrystals (PNCs) show promising applications in recognizing ionic and molecular species because of their excellent optical properties. However, lead halide PNCs have some limitations when they are used as probes for sensing aqueous media. Here, we introduce trypsin (Try) a bioligand the synthesis cesium chloride (CsPbCl3) with high water stability. The as-fabricated Try-CsPbCl3 λEm/Ex at 433/370 nm quantum yield 17.26%. fluorescence emission spectral characteristics demonstrated that water-stable acted fluorescent probe detection hydroxyl radical (•OH) via turn-off mechanism. PNCs-based approach displayed good selectivity water, showing wider linear range (0.01–5 µM) remarkable limit 3.10 nM radical. as-prepared were to be facile •OH samples, which signifies exhibited broad cell imaging.

The escalating issue of phenol-containing wastewater necessitates the development efficient and sustainable treatment methods. In this context, we present a novel composite photocatalyst comprising ZnFe2O4 (ZFO) nanoparticles supported on nanocellulose (NC), aimed at addressing environmental challenge. synthesis involved facile hydrothermal method followed by impregnation ZFO onto NC matrix. morphology structure ZFO, NC, ZFO/NC were investigated TEM, SEM-EDX, UV–vis, FT-IR, XRD, XPS analyses. as weakly magnetic semiconductor catalytic material, was utilized in photocatalytic experiments under field conditions. By controlling electron spin states through field, electron–hole recombination suppressed, resulting improved performance. results demonstrated that 43% 76% degradation achieved after 120 min irradiation due to 0.5ZFO/NC treatment. Furthermore, highest efficiency, showing promising recyclability maintaining its activity three cycles use. This study underscores potential for treatment, offering avenue remediation.
