A highly selective solution and film based sensor for colorimetric sensing of arginine in aqueous and blood samples.

A benzothiazole-azo based sensor (BTAN) was developed for rapid and on-site detection of arginine. The sensor's selectivity in a semi-aqueous medium was thoroughly investigated, focusing on the colorimetric response to arginine in the presence of 11 different amino acids. Notably, the limit of detection (LOD) for arginine was determined to be 0.

Solution and gaseous phase sensing of formaldehyde with economical triphenylmethane based sensors: a tool to estimate formaldehyde content in stored fish samples.

The use of formalin to preserve raw food items such as fish, meat, vegetables . is very commonly practiced in the present day. Also, formaldehyde (FA), which is the main constituent of formalin solution, is known to cause serious health issues on exposure.

Extending the Chemistry of Reaction between BODIPY and Cyanide Ions: An Application in Selective Sensing of Fluoride and Cyanide Ions.

A novel colorimetric BODIPY-based probe for selective detection of fluoride and cyanide has been developed. The color of the solution significantly changes upon addition of fluoride and cyanide ions with detection limits of 2.2 × 10 and 1.
