WebApr 12, 2024 · These observations demonstrate the superiority and feasibility of our ES-tailored strategy. Here, we can see that the laser spectrum in the ES system has a red shift of about 2.1 nm compared with the control system. We note that a larger excitation density corresponds to a decrease in the refractive index . In the ES system, lower lasing ... WebJun 29, 2024 · A subpopulation of fluorophores gets selectively excited upon excitation at the red edge. This subpopulation of fluorophores interacts strongly with polar solvent molecules in the excited state, thereby leading to slower rotational mobility and increased anisotropy of these ‘solvent-relaxed’ fluorophores.

WebRed- edge excitation spectra method is very sensitive to the changes that occur in the microenvironment of the Trp residues. For example, Trp residues of intact lens protein from rat exhibit an emission shift of 14 nm upon varying the excitation from 290 to 308 nm. Photodamaging the lens induces an emission shift of 24 nm (Rao et al. 1989).
