Sensing the cyanide metabolite 2-aminothiazoline-4-carboxylic acid (ATCA) by surface enhanced raman spectroscopy (SERS) is my task in the lab. We are currently working on building SERS sensors to give maximum enhancement in raman signals and analyzing ATCA with those sensors. I have also worked on understanding chemistry of ATCA (working with pH and reacting ATCA to give best enhancement on sensors). The main idea here is to built a cyanide analyzing technique (instrument) which is very convenient, inexpensive and more portable. ATCA is one of the most stable cyanide metabolite and is formed in the body when cyanide reacts with cystine.
