This research improves fluorescent imaging by enhancing the brightness of long-wavelength dyes. By encapsulating flexible squaraine dyes within macrocyclic rings, molecular motion is restricted, reducing energy loss and increasing light emission. The result is brighter, clearer imaging, enabling better visualization of biological structures such as cells and cancer tissue.

This talk explains how precise timekeeping underpins technologies like GPS and how atomic clocks achieve extreme accuracy using atomic oscillations. The research explores a new “active atomic clock” where atoms generate their own light, enabling even greater precision. Improved clocks could advance navigation, physics research, and our understanding of the universe.
