Many biological polyelectrolytes are capable of undergoing a fluid-fluid phase separation known as complex coacervation. Coacervates were prepared using hyaluronic acid (HA) and a recombinant fusion protein consisting of mussel adhesive motifs and the RGD peptide (fp-151-RGD). The low interfacial energy of the coacervate was exploited to coat titanium (Ti), a metal widely used in implant materi...

  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...

Coacervate micro-droplets produced by liquid-liquid phase separation are increasingly used to emulate the dynamical organization of membraneless organelles found in living cells. Designing synthetic coacervates able be formed and disassembled with improved spatiotemporal control is still challenging. In this chapter, we describe design photoswitchable coacervate droplets short double stranded D...

The aim of this work was to study the potential application edible films obtained by complex coacervation promoted electrostatic interactions between positively charged chitosan (CH) 3% (w/w) and negatively whey protein isolate (WPI) (w/w). Preliminary assays turbidimetry were made in order find optimal CH-to-WPI mass ratio for coacervation. maximum turbidity CH:WPI 0.1:1 dispersions CH/WPI (bo...

Polyelectrolyte complexes (PECs) between poly(acrylic acid) (PAA) and poly(diallyldimethylammonium chloride) (PDADMAC), a model system forming coacervate particles via electrostatic interaction at pH 10, were prepared by a stopped-flow (SF) fast mixing technique at different mixing charge ratios (z) and ionic strengths. Both PEC final morphologies prepared by either SF or manual one-shot mixing...
