The layer-by-layer (LbL) deposition technique is a self-assembly process that allows the coating of material's surface with nanostructured layers of polyelectrolytes, allowing to control several surface properties. This technique presents some advantages when compared with other thin film assembly techniques, like having the possibility to coat surfaces with complex geometries in mild condition...

The “millifluidic” technique could be considered as a novel approach for encapsulation of bioactive compounds and has promising perspective in the field food engineering or pharmaceutical science. In this study, we aim to optimize cinnamon essential oil (CEO) by droplet-based millifluidic with four responses: efficiency (EE), loading capacity (LC), sphericity factor (SF) size calcium-alginate m...

A new, novel promising technology for obtaining controlled release and enhancing the bioavailability is a combination of mucoadhesion principle and microencapsulation to result in mucoadhesive microcapsules. Mucoadhesive microcapsules consist of either entirely of a mucoadhesive polymer or having an outer coating enclosing the drug particles. They facilitate an intimate and prolonged contact wi...

background and objective: the opportunistic pathogen pseudomonas aeruginosa secrets a capsule-like polysaccharide called alginate which is important for evasion of host defenses, especially in patients with suppressed immunity. method of alginate determination has an important role in the study of microbial alginate. in this study, a novel method for alginate determination by highperformance li...

Film-forming solutions based on four types of biopolymers were prepared and their rheological properties determined. High methylated apple pectin sodium alginate used at the concentrations 1%, 1.5%, 2%, whereas soy protein isolate pork gelatin obtained 4%, 8%, 12%. The parameters determining production appropriate type packaging film or edible coating are setting time substrate, regardless its ...

The present study was aimed to develop and evaluate Albendazole microcapsules using guar gum, a natural polymer for colon-specific delivery for better treatment of Helminthiasis, Filariasis, and colorectal cancer by avoiding the side effects. Microcapsules were prepared by the use of different concentrations of sodium alginate and guar gum. The polysaccharides guar gum reacted with sodium algin...

The aim of this study was to evaluate a new packaging system in which the paper covered with solution sodium alginate and cinnamon essential oil (CEO) that used as for burger beef. papers were characterized their physical, optical, mechanical, sorption properties. In addition, burgers evaluated antioxidant activity, lipid oxidation, color difference. total, four treatments developed: Con: witho...

Enhanced vascularization at sensor interfaces can improve long-term function. Fibrin, a natural polymer, has shown promise as a biomaterial for sensor coating due to its ability to sustain endothelial cell growth and promote local vascularization. However, the culture of cells, particularly endothelial cells (EC), within 3D scaffolds for more than a few days is challenging due to rapid loss of ...
