Turbidity and light scattering measurements, along with phase contrast microscopy, were used to follow the processes leading to coacervation when aqueous solutions of bovine serum albumin (BSA) and poly-(dimethyldiallylammonium chloride) (PDADMAC) were brought from pH = 4 to 10. The state of macromolecular assembly of complexes formed between BSA and PDADMAC prior to and during the pH-induced c...

Abstract Background The electrostatic interactions between polysaccharides and proteins are an interesting field in the complex coacervation. PH mixing ratio have major effect on complexation coacervates structure. Hence, it is necessary to find optimum pH of as well understanding thermal, mechanical, structural characterization coacervates. Thus, changes complexes sodium caseinate (NaCas) high...

The first life was believed to emerge in the early Earth via a process involving synthesis of organic compounds and formation protocells. However, it is still puzzle how protocell with hierarchal structure desirable functions spontaneously generated non-living environment composed mainly water minerals. In this work, using muscovite as an example minerals, we systemically studied coacervation p...

  In the present study, the effect of stirring speed and the type of cross linking agent on the size and formation of microencapsulated Silver carp (Hypophthalmichthys molitrix) oil were investigated. The gelatin/gum Arabic was used for encapsulating and the capsules were prepared by complex coacervation. Microcapsules were analyzed by optical microscopy technique and particle size analyzer. Re...

The chemistry of mussel adhesion has commanded the focus of much recent research activity on wet adhesion. By comparison, the equally critical adhesive processing by marine organisms has been little examined. Using a mussel-inspired coacervate formed by mixing a recombinant mussel adhesive protein (fp-151-RGD) with hyaluronic acid (HA), we have examined the nanostructure, viscosity, friction, a...

In this study for the first time the effect of high-pressure CO2 on the coacervation of alpha-elastin was investigated using analytical techniques including light spectroscopy and attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopic imaging and circular dichroism (CD) spectroscopy. The coacervation behavior of alpha-elastin, a protein biopolymer, was determined at tem...
