Sodium alkyl sulfate micelles are predicted to grow as a power law of the total counterion salt concentration, Yaq, in the aqueous phase as follows: NA = K~(Y~~)Y, where N A is the micelle aggregation number and ~2 and y are constants which are estimated from the critical micelle concentration and the apparent degree of counterion attachment. For sodium dodecyl sulfate, NA = 162(Y,q)1/4 is pred...

The in situ formation of injectable silk fibroin (SF) hydrogels have potential advantages over various other biomaterials due to the minimal invasiveness during application. Biomaterials need to gel rapidly under physiological conditions after injection. In the current paper, a novel way to accelerate SF gelation using an anionic surfactant, sodium dodecyl sulfate (SDS), as a gelling agent is r...

The protein composition of Escherichia coli W3110 grown in the presence and absence of 5% sodium dodecyl sulfate (SDS) was examined by two-dimensional gel electrophoresis. In SDS-grown cells, at least 4 proteins were turned on, 13 were turned off, 15 were elevated, and 15 were depressed. The 19 unique and elevated SDS-induced spots constituted 7.91% of the total 35S-labeled protein. There was n...

The interaction of detergents with photosynthetic systems was studied early by Emil Smith (l), who pointed out the utility of anionic detergents for dispersing chloroplast material. Smith obtained what appeared to be subunits of the pigment complex, and characterized these components by ultracentrifugation. Subsequently, a number of investigators have studied the enzymatic capabilities of chlor...

Sodium dodecyl sulfate (SDS) and other alkyl sulfates, provided they contain a minimum of 12 carbon atoms (or 322 A in length), stabilize mouse interferon (MIF) in the presence of urea, 2-mercaptoethanol, and heat. When MIF is treated with the alkyl sulfates in the absence of urea and 2-mercaptoethanol, all alkyl sulfates inactivate MIF to the same extent. This suggests that the stabilizing eff...

We report a facile route to selectively deposit and arrange palladium (Pd) nanoparticles on single-walled carbon nanotubes (SWCNTs) having sub 10 nm diameter by using supramolecular self-assembly of sodium dodecyl sulfate (SDS) as a soft template.
