: He is a pioneer in using Photoinduced Electron Transfer (PET) to design fluorescent sensors that "switch on" in the presence of specific analytes.
: This technology has been foundational in developing blood gas analyzers and other medical sensors that provide rapid, bedside results. prasannajit de silva
His most influential contribution is the development of , which apply the principles of Boolean logic to chemical systems. By using molecules that respond to specific chemical or physical inputs—such as pH levels or metal ions—with a visual output (fluorescence), his research enabled the creation of "intelligent" molecules capable of sensing and processing information at a molecular level. Key Contributions and Impact : He is a pioneer in using Photoinduced
