Tryptophan pyrolysis
WebA new sensor for Hg 2+ and cysteine detection has been synthesized and tested. The sensor based on cinamaldehyde and pyrimidine absorbs visible light when exposed to Hg 2+ and becomes colored. The sensor only changes color due to Hg 2+ and does not change when exposed to some other metal ions. Calculations show the change in color is due to … WebPanagiotis Klonos received his degree in “Applied Mathematical and Physical Sciences’’ by the National Technical University of Athens (NTUA) in 2007 and his MSc in “Microsystems and Nanodevices” also in NTUA in 2009.
