We report on the development of a new array-based screening flat platform with the potential to be used as a high-throughput device based on biomimetic polymeric substrates for combinatorial cell/3D biomaterials screening assays in the context of tissue engineering. Polystyrene was used to produce superhydrophobic surfaces based on the so-called lotus effect. Arrays of hydrophilic regions could...

The purpose of the research was to formulate microspheres of acyclovir (ACV) using mucoadhesive polymers, sodium alginate and chitosan. Calcium chloride was used as the ionotropic gelling agent. Sodium alginate was crosslinked by calcium chloride leading to a slower release of the drug. Chitosan which is a cationic polymer interacted with sodium alginate, an anionic polymer, to form an interpol...

Momordica grosvenorii saponin (MGS), as a promising dietary supplement with remarkable biological properties, has poor stability under acidic conditions and thus hinders its application in functional foods. In this study, capsules of chitosan sodium alginate were successfully prepared to enhance the MGS. The optimized parameters for preparing MGS established. Sodium 20.8 mg/mL triplication powd...

There are several natural polymers such as carrageenan, alginate, chitin or chitosan that are classified as polysaccharides. One of the most promising is chitosan, deacetylated derivative of chitin, produced from shellfish wastes or fungi [15]. Irradiation of this polymer led the reduction of molecular weight by scission of glycosidic linkage. As compared to the conventional techniques, like ac...

Tissue sealant is a material that used as an adhesive to bond two tissue surfaces during surgery. Chitosan and alginate are natural macromolecules manufacture hydrogels sealants because these materials can strengthen bonds the mechanical properties of sealants.

In the present study an attempt was made to prepare alginate floating microparticles by ionotropic gelation method with calcium carbonate (CaCO3) 1% w/v in gelation medium used as gas-forming agent for oral delivery of Ofloxacin. Chitosan was used to enhance the drug encapsulation efficiency. Various physiochemical properties such as particle size, shape, in vitro buoyancy and drug release was ...

Protein–polysaccharide biopolymer particles composed of potential acrylamide inhibitors, including zein, chitosan, alginate, and pectin, were used for mitigation in this study. The synergistic effect zein polysaccharides complex was hypothesized to inhibit formation at high temperature. A reaction model utilizing a glucose asparagine solution heated 170 °C 30 min heating block implemented. Zein...

β-galactosidase simply known as lactase is a significant enzyme in food industry mainly used to hydrolyse lactose in milk. In addition to provide lactose free milk for lactose intolerant people, hydrolysis of lactose avoids textural problems in frozen milk products. β-galactaosidase from different sources has been immobilized on many various type of matrixes including chitosan, alginate, sepabe...
