Stability of four dissimilar basic proteins (chymotrypsinogen A, ribonuclease A, cytochrome c, lysozyme) in the complex with four polyanions (heparin, poly(vinylsulfate), poly(4-styrene-sulfonate), Nafion) has been studied by differential scanning calorimetry. The polyanions were chosen because of their different charge density

Differential scanning calorimetry, viscometry, optical and CD spectroscopy were used to characterize the influence of two polyanions, poly(vinylsulfate) (PVS), and poly(4-styrene-sulfonate) (PSS) on thermal transition reversibility of ferricytochrome c at or near isoelectric pH. In these conditions, both PVS and

A potentiometric titration method using a cationic surfactant as an indicator cation and a plasticized poly(vinyl chloride) membrane electrode sensitive to the cationic surfactant is proposed for the determination of polyhexamethylene biguanide hydrochloride (PHMB-HCl), which is a cationic polyelectrolyte.

Much stronger binding is seen in aqueous solutions between the anionic polyelectrolyte potassium poly(vinyl sulfate) and the substitution labile aluminium(III) than with the kinetically inert chromium(III). This strongly supports the idea that entropy driven water loss from the hydration sphere

The properties of the complexes of ferricytochrome c with two different polyanions--poly(vinylsulfate) and poly(4-styrene-sulfonate)--with a comparable charge density but with the different size of the uncharged part of their molecules have been studied by means of optical spectroscopy, differential scanning

Layer-by-Layer (LbL) Assembly, A "Gentle Yet Flexible" Method Toward Functional Biomaterials

Recently, layer-by-layer (LbL) assembly has emerged as a versatile, gentle and, simple method for immobilization of functional molecules in an easily controllable thin film morphology.1,2 In this short review, we introduce recent advances in functional systems fabricated by using the mild, yet adaptable LbL technique.

Polyelectrolyte Multilayer Films and Membrane Functionalization

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
