Jan 13, 2023 (Nanowerk News) Photothermal therapy (PTT) has attracted considerable attention for tumor treatment due to its unique advantages in minimal invasiveness and spatiotemporal selectivity. Melanin is a kind of multifunctional pigment found widely in mammals, plants and microbes, with great prospects as a PTT agent for cancer treatment....
Ultraviolet nanophotonics enables autofluorescence correlation spectroscopy on label-free proteins with a single tryptophan
Jan 13, 2023 (Nanowerk News) Proteins are naturally fluorescent in the ultraviolet, offering an appealing approach to probe proteins in their native state without introducing any external fluorescent label. The UV autofluorescence of proteins is based on the presence of tryptophan amino acids, which typically occur as 1 to 5...
