The utilization of natural gum polysaccharides as the vehicle for drug delivery systems and other biomedical applications has increased in recent decades. Their biocompatibility, biodegradability, price are much cheaper than materials. It is also renewable available massive amounts, which main reasons its use pharmaceutical applications. Gum can be easily functionalized with polymers to enhance...

In this paper, we report on the fluorescence enhancement of Eu coordination complexes in dilute solutions through electrostatic complex micelle formation with an oppositely charged block polyelectrolyte. The coordination complexes alone are oligomeric structures which have many ends where partially coordinated europium is exposed to water. In the presence of oppositely charged polyelectrolytes,...

Advances in functionally biopolymer systems have provided new opportunities on basic science studies and bioengineering applications. In this review, the recent data on interaction mechanisms of synthetic polyelectrolytes with proteins and physico-chemical criteria for the construction of functionally biopolymer systems are reviewed. Also, the structure and structural-chemical features of prote...

Recent studies have pointed out the importance of polyelectrolyte assembly in the elaboration of innovative nanomaterials. Beyond their structures, many important questions on the thermodynamics of association remain unanswered. Here, we investigate the complexation between poly(diallyldimethylammonium chloride) (PDADMAC) and poly(sodium acrylate) (PANa) chains using a combination of three tech...
