Binding and relaxation behaviour of prodan and patman in phospholipid vesicles: a fluorescence and 1H NMR study

New fluorescent probes for detection and characterization of amyloid fibrils

“…In steadystate fluorescence measurements this phenomenon manifests itself in the red shift of emission maximum with increasing excitation wavelength [31]. As illustrated in Fig.…”

Exploring membrane organization and dynamics by the wavelength-selective fluorescence approach

“…REES is indeed observed when the above criteria are satisfied (Ladokhin et al, 1991;Mukherjee, 1993, 1999a,b;Chattopadhyay and Rukmini, 1993;Hutterer et al, 1996;Chattopadhyay et al, 1997;Ghosh et al, 1997;Santos et al, 1998;MacPhee et al, 1999;Raja et al, 1999;Granjon et al, 2001). In addition, it is preferable that the membrane-embedded molecule has only one fluorescent group which has a unique location in the membrane and not a distribution of locations.…”

Effect of alkyl chain length and size of the headgroups of the surfactant on solvent and rotational relaxation of Coumarin 480 in micelles and mixed micelles

“…Bagchi et al 11 ascribed such retardation in solvent relaxation to the freezing of the translational mode of water molecules inside ␥-CD cavity. Solvation dynamics in micelles, [12][13][14][15] aqueous [16][17][18][19] and nonaqueous 20-23 reverse micelles, vesicles, [24][25][26][27] DNA, 28 and amphiphilic star-like macromolecules 29 have also been investigated. The results in these solvation dynamics experiments reveal much slower dynamics compared to bulk water.…”
