Self-assembled polyelectrolyte–surfactant complexes in the solid state and as nanoparticles are the topic of this review. These materials combine the properties of polymers (mechanical stability) and surfactants (formation of highly ordered mesophases). Their building principle is modular which allows a great variety in their designing as well as their structural and functional properties. Typi...

This review article aimed to study chitosan as a material based in wound dressing preparation. The method this is the approximation method. articles were obtained from national and international journals such Scopus, PubMed, Google Scholar by using keywords "Chitosan", "Wound Healing", "Biomedical Application". inclusion criteria of are: books contains as, published last ten years, not article....

Phycocyanin is a protein-chromophore structure present in Arthrospira platensis commonly used as blue-colorant food. Color losses of phycocyanin can be reduced by electrostatic complexation with ?-carrageenan. The aim this study was to investigate the effect molecular weight ( M W ) ?-carrageenan on color stabilization complexes formed and Samples were heated 70 or 90°C at pH 3.0 stored 25°C fo...

a new series of transition metal complexes of co(ii), ni(ii), cu(ii) and zn(ii), has beensynthesized from the knoevenagel condensate schiff base ligand(l) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. structural features were determinedby spectral and analytical techniques. square-planar geometry has been adopted by thecomplexes except cobalt complex which ...

The low transfection efficiency of chitosan is one of its drawbacks as a gene delivery carrier. Low molecular weight chitosan may help to form small-sized polymer-DNA or small interfering RNA (siRNA) complexes. Folate conjugation may improve gene transfection efficiency because of the promoted uptake of folate receptor-bearing cells. In the present study, chitosan was conjugated with folate and...

Chitosan, a biocompatible polysaccharide having antimicrobial efficacy, is highly useful for biomedical and other applications. How chitosan properties can be tailored continues to attract intense research interest. Herein, chitosan/carboxymethyl cellulose (CMC) materials filled with montmorillonite (MMT) were thermomechanically processed resulting in excellent nanoclay dispersion. Inclusion of...
