Charge Density

We use a library of polyacrylamide-based polymers to investigate the roles of charge density and hydrophobicity in determining the phase behavior and viscoelasticity of poleyelectrolyte complex coacervates The polymers which are made by post-polymerization functionalization of poly(N-acryloxy succinimide) have charged monomer fractions between 60 and with the balance comprised of

Polyacrylamide Hydrogel Synthesis and Functionalization

Polyacrylamide (PAAm) hydrogels are commonly employed to ensure soil hydration in horticulture but studies have shown that they have a minimal effect on crop life and quality The reasons for this poor performance are not understood since the commercial hydrogels have not been adequately characterized PAAm hydrogels were synthesized and their properties were measured along with

Hydrophilic polyacrylamide gel

Hydrophilic polyacrylamide gel (HPG) is a combination of 2 5-5% polyacrylamide a synthetic polymer suspended in 95-97 5% apyrogenous water This is the only injectable implant that remains soft once it has been injected After injection the water content is absorbed by the body whilst the HPG becomes encapsulated

Tunable Hydrophobicity in DNA Micelles : Design

The hydrophobicity was imparted by the introduction of a dodec-1-yne chain at the 5-position of the uracil base which allowed precise and simple tuning of the hydrophobic properties through solid-phase DNA synthesis The micelles formed from these modified DNA sequences were characterized by atomic force microscopy dynamic light scattering

Cell surface components of Streptococcus sanguis

Cell surfaces of aggregation adherence and hydrophilic variants of Streptococcus sanguis were compared with cell surfaces of the parent strain with regard to their protein and antigenic constituents Cell surface molecules were released by digestion with mutanolysin Extraction with sodium dodecyl sulfate (SDS) urea lithium diiodosalicylate and boiling water did not solubilize any material

Surface Hydrophobicity Changes of Two Candida albicans

Cell surface hydrophobicity (CSH) of Candida species enhances virulence by promoting adhesion to host tissues Biochemical analysis of yeast cell walls has demonstrated that the most significant differences between hydrophobic and hydrophilic yeasts are found in the acid-labile fraction of Candida albicans phosphomannoprotein suggesting that this fraction is important in the regulation of the
