The diverse nature of Chloramine-T, the sodium salt of N-chloro-p-toluenesulfonamide, abbreviated as CAT, acts as a source of halonium cation and nitrogen anion; acting as both base and nucleophile it reacts with broad range of functional groups and brings divergent molecular transformations to synthetic chemistry and also finds utility in analytical fields.

A highly ordered Ag-TiO₂ NPA SERS substrate could well adsorb organic molecules of R6G to achieve sensitive detection. The used SERS substrate of a R6G-Ag-TiO₂ NPA could be regenerated through UV-excited photocatalytic degradation of R6G to achieve the self-cleaning and recycling application of the Ag-TiO₂ NPA SERS substrate.

As an important biomarker, NADH is associated with breast cancer. In this paper, silver-plated gold core–shell nanoparticles containing Raman signalling molecules were synthesized. Based on SERS technology, the detection of NADH in complex biological samples of serum was achieved, offering the possibility to expand the early diagnosis of breast cancer.

Novel 4-anilinoquinazoline derivatives were synthesised and evaluated for their cytotoxicity on A431, HUVEC, and HU02 using MTT assay. Docking studies were done on synthesised compounds (8a–8l) on EGFR and VEGFR-2. Furthermore, a wound healing assay was done to examine the effects of 8e, 8i, and 8l on cell migration.

Substrate selectivity comparison of Escherichia coli and human tyrosyl-tRNA synthetases revealed two tyrosine derivatives exhibiting greater binding affinity to the bacterial enzyme.
