Bionanocomposites are a novel class of nanosized materials. They contain the constituent biological origin and particles with at least one dimension in range 1–100 nm. There similarities nanocomposites but also fundamental differences methods preparation, properties, functionalities, biodegradability, biocompatibility, applications. The article includes two parts. Bionanocomposite definition classification along nanoparticles, biomaterials, their preparation initially reviewed. Then,...
Abstract Cellulose possesses excellent properties, but its performance characteristics do not satisfy human requirements completely, which has soured a constant effort to improve features. Currently, cellulose is combined with inorganics in process called mineralization that results novel type of materials referred as bio‐nanocomposites. There are many examples mineralized tissues superior properties living nature. This circumstance gives us reason biomimic them by compounding biopolymers...
Hydrogels are prepared by means of progressive acidification xanthan solution containing dispersed chitosan particles in noncharged state at pH a little larger than pKa this polysaccharide. The following shift causes gradual charging macromolecules that involved into electrostatic interactions with oppositely charged xanthan. This triggered self-regulating processes polysaccharide self-organization supramolecular structures. Fibrillation or capsulation was observed depended on the charge...
Bionanocomposites are formed through the electrostatic interactions of exfoliated clay nanoparticles initially dispersed in an aqueous solution with chitosan macromolecules that gradually charged course a progressive pH decrease by chemical acidulating agent to exclude phase separation.
DNA-chitosan (DNA-CS) hydrogels were prepared on the basis of interpolyelectrolyte complexes (IPEC) in a co-assembled regime by situ charging polysaccharide DNA solution. In contrast to poorly controlled coacervates formed upon mixing and CS solutions, stable DNA-CS IPEC are at near-stoichiometric ratios chitosan ionogenic groups. Structure, stability, ion absorption properties such depended strongly ratio between cationic (CS) anionic (DNA) counterparts hydrogels. Abundant amino-...
Abstract The article is an overview of our recent study on some particular aspects polyelectrolyte complex (PEC) formation by oppositely charged polysaccharides when they are brought into contact in aqueous solutions. This type complexation can lead to the thickening effect, jellification or PEC precipitation that find numerous applications a variety fields from regulation rheological characteristics solutions fabrication functional materials layer-by-layer technique. Our focus was...
We fabricated hybrid (CSSQ) membranes from chitosan and poly(aminopropyl/phenylsilsesquioxane) (PAPSQ) blends via a sol–gel reaction solution casting followed by crosslinking with glutaraldehyde. The CSSQ were then used for loading of 5-fluorouracil (5-FU) as an anticancer drug well templates the production silver nanoparticles (AgNPs). physicochemical properties examined using UV-visible spectroscopy, Fourier transform infrared X-ray diffraction, thermogravimetric analysis scanning electron...
Biosilica, synthesized annually only by diatoms, is almost 1000 times more abundant than industrial silica. Biosilicification occurs at a high rate, although the concentration of silicic acid in natural waters ~100 μM. It neutral aqueous solutions, ambient temperature, and under control proteins that determine formation hierarchically organized structures. Using diatoms as an example, fundamental differences between biosilicification traditional sol–gel technology, which performed with...

Films containing a new crystalline polymorph are prepared by one-pot technique combining the formation of building blocks clay nanoplatelets with chitosan macromolecules and their evaporation-induced self-assembly.
Abstract Fibrillary cellulose and nanocellulose are widely applied as fillers for the improvement of mechanical properties, thermostability, biodegradability polymers. Here, an opposite concept is suggested which to use structure‐forming directing scaffold, whereas polymers serve its modification. Cellulose possesses excellent but they badly affected by water; strength drops sharply, cellulosic materials swell, become dimensionally unstable, susceptible fungal degradation. The deterioration...
Abstract Bionanocomposites in the self-organized regime are prepared when chitosan is gradually charged course of progressive change pH by hydrolyzing D -glucono- δ -lactone solutions nanoparticles bearing negative charges on their surface. This novel approach applicable to formation monolithic hydrogels and films. Here bionanocomposites with clay saponite sepiolite having various geometry oxidized multiwall carbon nanotubes considered. Structural organization films studied scanning...
Abstract Graphene oxide ( GO ) was combined with wheat gluten WG and chitosan CS to prepare bionanocomposite films using a casting method.
