Prasannajit De Silva Access

: A retired Sri Lankan military officer and former diplomat.

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 Electron Transfer (PET) to design fluorescent sensors that "switch on" in the presence of specific analytes. prasannajit de silva

: His work laid the groundwork for human-scale computations performed by molecular systems, including edge detection in object recognition.

: A Sri Lankan-American actor and director known for roles in Inventing Anna and various Broadway productions. : A retired Sri Lankan military officer and former diplomat
