Our findings reveal that GO effectively quenches R6G fluorescence across all tested pH levels, with the most significant quenching observed at pH 7. This quenching efficiency is attributed to optimal electrostatic interactions and efficient charge transfer between GO and R6G at neutral pH. At pH 3, the quenching efficiency is moderately reduced due to partial protonation of GO, which weakens electrostatic interactions but maintains hydrogen bonding. At pH 11, the quenching efficiency is lowest, likely due to increased electrostatic repulsion and reduced charge transfer resulting from deprotonation of GO. Ultrafast time-resolved absorption spectroscopy further confirmed the dynamic nature of the quenching process, showing distinct differences in relaxation kinetics across the pH spectrum.

The fabricated samples were excited using two laser sources (405 and 530 nm) to record the fluorescence spectra. Our findings indicate that nanoparticles ranging in size from 15 to 78 nm may not have a significant impact on the fluorescence intensity or the peak wavelength at which maximum fluorescence occurs.

The optimal concentration of nanoparticles in the dye solution was determined based on the optimum values of scattering spectral width and anisotropy parameter.

In this work, we have used four different sizes of a molecular crowder, polyethylene glycol (PEG), to analyze the unfolding and refolding kinetics of an iLBP protein, CRABP I, using urea as chemical denaturant. In general, the stability of the native state of the protein is boosted by the presence of crowding agents in the solution. However, our findings show that not only the type of crowder but also the crowder size played a key role in the effects of excluded volume. In case of lower molecular weight of PEG (M.W. 400), even at 200 g/L concentration, only the viscosity effect is observed, whereas for higher molecular weight of PEG (M.W. 1000), both the viscosity effect and excluded volume effect are noticed, and even at a higher concentration (200 g/L) of PEG 1000, the excluded volume predominates over the viscosity effect. Using the transition state theory, we were also able to determine the free energies of activation for the unfolding and refolding studies from their respective rate constants.
