Photoinduced electron transfer in a protein-surfactant complex: Probing the interaction of SDS with BSA
Article Abstract:
Photoinduced fluorescence quenching electron transfer from N,N-dimethyl aniline to different 7-amino coumarin dyes is investigated in sodium dodecyl sulfate (SDS) micelles and in bovine serum albumin (BSA)-SDS protein-surfactant complexes by using steady state and picosecond time resolved fluorescence spectroscopy. The results have shown that the slower rotational relaxation and translational diffusion of coumarin 151 (C-151) are arising from the different location of coumarin 151 compared to coumarin 152 and coumarin 481.

Interaction forces between BSA layers adsorbed on silica surfaces measured with an atomic force microscope
Article Abstract:
An atomic force microscope (AFM) in conjunction with the colloid probe technique is used to measure the interaction forces between bovine serum albumin (BSA) layers adsorbed on silica surfaces. The results indicate that the AFM colloid probe technique can provide a useful way of directly quantifying the interaction of biological macromolecules.

The distribution of electron donor-acceptor potential on protein surfaces
Article Abstract:
Electron donors and acceptors are distributed at random on the surface of urease and cytochrome b5, but not on human serum albumin. The results suggest the characteristic length of the AB interactions determining protein adsorption greater than that implied by macroscopic surface tension measurements.
