Green synthesized AgNPs as a probe for colorimetric detection of Hg (II) ions in aqueous medium and fluorescent imaging in liver cell lines and its antibacterial activity.

The present research aimed at green synthesis of Ag nanoparticles (AgNPs) based colorimetric sensor using persimmon leaf extract (PLE) for selective detection of mercuric ion (Hg). Optimization of reaction conditions viz. pH, concentration of PLE, time was done and further AgNPs were characterized using UV, IR, FE-SEM, EDX, XRD and TEM analysis.

Medicinal and Biological Significance of Phenoxazine Derivatives.

Since 1887, phenoxazine derivatives have attracted the attention of chemists due to their versatile utility, industrially and pharmacologically. Literature is found abundant with various pharmacological activities of phenoxazine derivatives like antitumor, anticancer, antifungal, antibacterial, anti-inflammatory, anti-diabetic, anti-viral, anti-malarial, anti-depressant, analgesic and many other drug resistance reversal activities. This review covers a detailed overview of the pharmacological application of phenoxazine nucleus, its chemistry and reactivity, and also illustrating the incorporation of different groups at different positions enhancing its biological application, besides some synthetic procedures.
