The effects of zinc oxide nanorod on the barrier, sorption isotherm and antibacterial properties of tapioca starch/bovine gelatin Bionanocomposite films were investigated. The nanorod-rich ZnO (ZnO-N) was homogenized by sonication and incorporated into tapioca starch/bovine gelatin solutions at different concentrations (e.g. 0.5, 2, and 3.5% w/w dried solid). Incorporation of 3.5% of nanopartic...

The process of moving hydrophobic amino acids into the core of a protein by desolvation is important in protein folding. However, a rapid and forced desolvation can lead to precipitation of proteins. Desolvation of proteins under controlled conditions generates nanoparticles - homogeneous aggregates with a narrow size distribution. The protein nanoparticles, under physiological conditions, unde...

A technique for the formation of gelatin thin films and composite coatings with silicon dioxide zinc oxide nanoparticles by spin coating has been developed. New data morphology structural characteristics formed nanocomposite were obtained atomic force microscopy. The dependences roughness parameters on content in polymer matrix are presented. It shown that introduction inorganic into structure ...

Calcium phosphate- (CaP-) based composite scaffolds have been used extensively for the bone regeneration in bone tissue engineering. Previously, we developed a biomimetic composite nanofibrous membrane of gelatin/β-tricalcium phosphate (TCP) and confirmed their biological activity in vitro and bone regeneration in vivo. However, how these composite nanofibers promote the osteogenic differentiat...

Peak 1 displays the adaptation of the fractionation conditions as described above to the siRNA oligonucleotide. With an increased initial cross-flow intensity the separation from the void peak, inherent to AF4 systems, will be enhanced (peak 2). The higher MW of the siRNA oligonucleotide compared to the ssDNA oligonucleotide permit the application of a 5 kDa cut-off ultrafiltration membrane Sim...

BACKGROUND Dental implants have become increasingly common for the management of missing teeth. However, peri-implant infection remains a problem, is usually difficult to treat, and may lead eventually to dental implant failure. The aim of this study was to fabricate a novel antibacterial coating containing a halogenated furanone compound, ie, (Z-)-4-bromo-5-(bromomethylene)-2(5H)-furanone (BBF...

UNLABELLED BACKGROUND The aim of this study is to investigate the functions of polymers and size of nanoparticles on the antibacterial activity of silver bionanocomposites (Ag BNCs). In this research, silver nanoparticles (Ag NPs) were incorporated into biodegradable polymers that are chitosan, gelatin and both polymers via chemical reduction method in solvent in order to produce Ag BNCs. Si...

The aim of this study was to evaluate intraocular biodistribution of a fluorescent polymeric nanosystem composed of chitosan and gelatin after intravitreal administration in rat eyes. The nanoparticles based on chitosan and gelatin were synthesized using a reverse emulsion-double cross-linking technique (ionic and covalent) and their structural characteristics are presented. Two units of 1% sus...
