Fluorescent organic nanoparticles (FONs) are a large family of nanostructures constituted by
organic components that emit light in different spectral regions upon excitation, due to the …

Fluorescent probes have been employed for more than half a century to study the structure
and dynamics of model and biological membranes, using spectroscopic and/or microscopic …

This study presents an extensive analysis of the predictive power of time-dependent density
functional theory in determining the excited-state properties of two groups of important …

Cholesterol is known for its role in maintaining the correct fluidity and rigidity of the animals
cell membranes and thus their functions. Assessing the content and the role of cholesterol in …

The second harmonic signal of an amphiphilic dye embedded in a lipid bilayer has been
calculated by combining molecular dynamics simulations and quantum chemistry …

The solvatochromic dye Laurdan is widely used in sensing the lipid packing of both model
and biological membranes. The fluorescence emission maximum shifts from about 440 nm …

Surface Second-Harmonic Generation (S-SHG) experiments provide a unique approach to
probe interfaces. One important issue for S-SHG is how to interpret the S-SHG intensities at …

Conspectus Light is ubiquitously available to probe the structure and dynamics of
biomolecules and biological tissues. Generally, this cannot be done directly with visible light …

In a recent study, spectroscopic observations of modified cholesterol in both lipid-coated
nanoparticles and liposomes provided evidence for a disorder-to-order orientational …

The development of a universal probe to assess the phase of a lipid membrane is one of the
most ambitious goals for fluorescence spectroscopy. The ability of a well-known molecule as …
