Nanomolar Detection of H(2)S in an Aqueous Medium: Application in Endogenous and Exogenous Imaging of HeLa Cells and Zebrafish.
Naha S, Thirumalaivasan N, Garai S, Wu SP, Velmathi S. Naha S, et al. ACS Omega. 2020 Aug 3;5(31):19896-19904. doi: 10.1021/acsomega.0c02963. eCollection 2020 Aug 11. ACS Omega. 2020. PMID: 32803086 Free PMC article.
Quenching of green emission of the receptor is observed only when H(2)S is present in water with a detection limit of 18 nM. Other competing anions and cations do not have any influence on the receptor's optical properties. The efficiency of H(2)S detection i …

Naphthalimide based smart sensor for CN(-)/Fe(3+) and H(2)S. Synthesis and application in RAW264.7 cells and zebrafish imaging.
Naha S, Wu SP, Velmathi S. Naha S, et al. RSC Adv. 2020 Feb 28;10(15):8751-8759. doi: 10.1039/c9ra07998j. eCollection 2020 Feb 27. RSC Adv. 2020. PMID: 35496571 Free PMC article.
Among all RSS (Reactive Sulphur Species), R shows selectivity for H(2)S through red colouration. Other coexistent anions, cations and RSS cause no discernible perturbation to the detection process. The detection of H(2)S is attributed to a chemodosimetric reduction …

Dual-Responsive Benzo-Hemicyanine-Based Fluorescent Probe for Detection of Cyanide and Hydrogen Sulfide: Real-Time Application in Identification of Food Spoilage.
Magesh K, Vijay N, Wu SP, Velmathi S. Magesh K, et al. J Agric Food Chem. 2023 Jan 18;71(2):1190-1200. doi: 10.1021/acs.jafc.2c05567. Epub 2023 Jan 5. J Agric Food Chem. 2023. PMID: 36602329
The measured detection limits for CN(-) (0.43 muM) and HS(-) (0.22 muM) ions are lower than the World Health Organization's (WHO) recommended levels in drinking water. We confirmed 1:1 stoichiometry ratio using Job's plot and observed good quantum yield for both ana …
