This study investigates the production of alginate microcapsules, which have been coated with the polysaccharide chitosan, and evaluates some of their properties with the intention of improving the gastrointestinal viability of a probiotic ( Bifidobacterium breve ) by encapsulation in this system. The microcapsules were dried by a variety of methods, and the most suitable was chosen. The work d...

Clinical treatment of orthopaedic tissue injuries often involves the use of titanium and titanium alloys with considerable research focusing on the surface modification of these materials. Chitosan, the partly deacetylated form of chitin, is one of the materials under investigation as surface coating for orthopaedic implants in order to improve osteo-integration and cellular attachment. In this...

Bone implants must be biocompatible and are usually built to promote osseointegration, e.g. by application of plasma spray calcium phosphate (CaP) coating. The risk of infection and biofilm formation on implant surfaces is a well-known problem. The combination of electrochemically deposited CaP coating with antibiotics may offer significant benefits. Here, we demonstrate an innovative in situ e...

Chitosan was modified with sodium hydroxide and polymerized in water with plant growth regulators, microfertilizer and other additives to give a novel environmentally friendly seed coating agent for rice. The results showed the seed coating agent has obvious biological effect through the germination test, bacteriostasis test, toxicological security test and field experiment. Compared with the t...

The sequential deposition of chitosan and pectin on a supported phospolipid bilayer was examined using a quartz crystal microbalance. Multilayer formation was observed. The coating of phospholipid-stabilized emulsion droplets through centrifugation in a stepped sucrose gradient, containing successive layers of pectin and chitosan, was then investigated. Microelectrophoresis of the emulsion drop...

Background and Objectives: Nowadays, to avoid the use of synthetic preservatives, which do more harm than good, numerous studies are currently focused on using natural ingredients to enhance food product quality and shelf life. Since no study has been conducted on combining coatings with electrolyzed water containing natural antimicrobial compounds, the present study has innovation and priority...

It is attractive to control the properties of macro objects and films by employing simple nanolayer composites, as in the case of nanoarchitectured Layer-by-Layer (LbL) coating. In this paper, we use chitosan as a surface-based pH buffer to protect adsorbed supramolecular fibres from pH-mediated disassembly. Protons are generated on a titania surface under illumination at 405 nm leading to an a...

As people in the 21st century become increasingly environmentally aware, environmentally friendly products have come into focus. As such, environmentally friendly textiles and eco-textiles have become an international trend in research and development. Poly(lactic acid) fiber, which is biodegradable, holds much promise, but it is difficult to deep dye. This study used chitosan, succine anhydrid...

Chitosan is a biopolymer that is being increasingly used in distinct areas such as pharmaceutical, biomedical, cosmetics, food industry and agriculture. Among the interesting biological activities that have been ascribed to chitosan, the antimicrobial activity is probably the one that generates the higher number of applications. Considering that feet present favorable conditions for microorgani...
