This study investigated the effects of a novel antibacterial film based on chitosan, carboxymethyl cellulose, sodium alginate, tea polyphenols, ascorbic acid, and tangelo peel extract postharvest quality reactive oxygen species metabolism fruit during storage. The composite significantly reduced decay rate weight loss, delayed reduction in total soluble solids titratable acidity, retained firmn...

Granisetron hydrochloride is most commonly used as an antiemetic agent in treatment associated with cancer chemotherapy induced nausea and vomiting. If the dosage form is designed in sustain release it provide more advantage for the antiemetic therapy. The purpose of this research was to study mucoadhesive buccal patches of Granisetron hydrochloride using the bioadhesive polymers chitosan and s...

Aim: to investigate and describe, through a systematic review, the biological behavior osteogenic potential of composite biomaterials containing hydroxyapatite (HA), alginate gelatin, in different associations, after vivo implantation. Materials Methods: for search selection articles, Medical Literature Analysis Retrieval System Online (PubMed/MEDLINE) Scientific Electronic Library (SciELO) dat...

The present study aims to develop a hydroxyapatite (HAP) based scaffold composite for orthopaedic applications and that, we adopt Casein (Cs) micelle assisted synthesis route the formation of composite. Following characterization various fluorine (2% 5%) substituted HAPs (FHAP), they have been tested release Ciprofloxacin (CIP) drug antimicrobial efficacy. physicochemical such as FTIR Raman con...

Bilayer films that combine chitosan and alginate, two natural polysaccharides, magnetic iron oxide nanoparticles (MNPs) were obtained. Physical microscopic observations revealed alginate interact strongly through their surfaces, which is attributed to the formation of a polyelectrolyte complex at interface. The diameter individual MNPs was about 10 nm, although in they appear arranged clusters ...

A series of composites based on nanohydroxyapatite (nHAp) and natural polysaccharides (PS) (nHAp/agar, nHAp/chitosan, nHAp/pectin FB300, nHAp/pectin APA103, nHAp/sodium alginate) was synthesized by liquid-phase two-step method and characterized using nitrogen adsorption-desorption, DSC, TG, FTIR spectroscopy, and SEM. The analysis of nitrogen adsorption-desorption data shows that composites wit...

We investigated the flow dynamics of microgel capsules in topographically patterned microfluidic devices. For microgels flowing through channel constrictions, or orifices, we observed three phenomena: (i) the effect of confinement, (ii) the role of interactions between the microgels and the channel surface, and (iii) the effect of the velocities of microgels prior to their passage through an or...

Recently, efforts have been focused on microparticles prepared with natural polymers such as alginates and chitosans. Sodium alginate in particular has been commercially applied and investigated due to its low cost and minimal processing requirements (Murata et al., 1993; Gombotz & Wee, 1998; Sezer & Akbuga, 1999a and b). The use of sodium alginate for microencapsulation has been extensively st...
