Guwahati, Aug 06: Indian Institute of Technology Guwahati researchers have developed an optical sensing device that can instantly detect a variety of toxicants in water and other biological samples. To address this challenge of water quality monitoring, the research team has developed a portable point-of-care testing device named E–Eye. Contrary to conventional laboratory based costly instruments, E–Eye is suitable for direct field deployment, where it can detect water toxicants right at the water source. During laboratory tests, the research team found that results shown by E–Eye are comparable to those of standard UV-Visible and Atomic Absorption spectrophotometers (AAS), while offering advanced digital integration functionality. The research team has tested more than 2700 samples with the developed device and recorded accurate results.
