The self-assembly behavior of a light-sensitive azobenzene-based surfactant, both in pure surfactant solutions and in the presence of a hydrophobically modified, water-soluble polymer, has been investigated using small-angle neutron scattering (SANS), light scattering, and UV-vis absorption techniques.

The effect of an azobenzene-based photoresponsive surfactant on fibril formation of beta-amyloid (1-40) (Abeta40) has been studied using small-angle neutron scattering (SANS), atomic force microscopy (AFM), and light scattering (LS) measurements.

We have used small-angle neutron scattering (SANS), and cryogenic transmission electron microscopy (cryo-TEM) to determine the structure of aggregates formed by the photoresponsive surfactants diethylene glycol mono (4',4-butyloxy, butyl-azobenzene) (C4AzoOC4E2) and diethylene glycol mono (4',4-hexyloxy, butyl-azobenzene) (C4AzoOC6E2) under different illumination conditions.

The cationic azobenzene surfactant undergoes a reversible photoisomerization upon exposure to the appropriate wavelength of light, with the visible-light (trans) form being more hydrophobic and, thus, inducing a greater degree of protein unfolding than the UV-light (cis) form.
Conformational changes as a function of photoresponsive surfactant concentration and light illumination were measured through shape-reconstruction analysis of small-angle neutron scattering (SANS) data.

Upon exposure to the appropriate wavelength of light, the azobenzene surfactant undergoes a reversible photoisomerization, with the visible-light (trans) form being more hydrophobic than the UV-light (cis) form.
Small-angle neutron scattering (SANS) measurements were used to provide detailed information of the protein conformation in solution.

The photoresponsive interaction of light-sensitive azobenzene surfactants with bovine serum albumin (BSA) at neutral pH has been investigated as a means to control protein folding with light irradiation.
Small-angle neutron-scattering (SANS) measurements are used to provide detailed information on the protein conformation in solution.

16898769 Wang SC, Lee CT Jr: Protein secondary structure controlled with light and photoresponsive surfactants. J Phys Chem B. 2006 Aug 17;110(32):16117-23.

The interaction of a light-responsive azobenzene surfactant with bovine serum albumin (BSA) has been investigated as a means to examine photoreversible changes in protein secondary structure.
Comparing the secondary structure changes induced by light illumination in the presence of the photoresponsive surfactant with previous measurements of the tertiary structure of BSA obtained from small-angle neutron scattering (SANS) allows the three discrete conformation changes in BSA to be fully characterized.
