Nanothickness encapsulation using a layer-by-layer technique has applications in several areas of diabetes research, including improved glucose sensors, islet cell transplantation and oral insulin delivery. We have fabricated microvesicles containing a fluorescence lifetime-based glucose sensing system, with bacterial glucose-binding protein as the glucose receptor. Such sensors are suitable fo...

Coating of lignin nanoparticles with chitosan and glucose oxidase allows for the green synthesis acrylic vinyl polymers in Pickering emulsions. The resulting dispersions offer a route to tough composites equipped antioxidant activity.

Lipid nanocapsules (LNCs) were modified by adsorbing sequentially dextran sulfate (DS) and chitosan (CS) on their surface by the layer-by-layer (LBL) approach. Tangential flow filtration (TFF) was used in intermediate purifications of the LNC dispersion during the LBL process. The surface modification was based on electrostatic interactions between the coating polyelectrolytes (PEs) and the LNC...

Chitosan is the deacetylated form of chitin and used in numerous applications. Because it is a good dispersant for metal and/or oxide nanoparticle synthesis, chitosan and its derivatives have been utilized as coating agents for magnetic nanoparticles synthesis, including superparamagnetic iron oxide nanoparticles (SPIONs). Herein, we demonstrate the water-soluble SPIONs encapsulated with a hybr...

Multifunctional mulberry silk fabrics with excellent temperatureand pH-sensitivity, antibacterial properties and permeability are successfully prepared by surface modification with PNIPAAm/chitosan/poly(ethylene oxide) nanofibers. The nanofibers deposited on the surface of mulberry silk fabric are produced by the electrospinning technique. The surface properties of mulberry silk fabrics were ch...

Safe and environmentally friendly oil-resistant packaging paper is strongly desired in the food packaging industry. In the present work, chitosan (CTS) and chitosan/cationic starch (CTS/CS) coated papers were prepared and characterized. The results indicated that both the CTS and CTS/CS coated papers were highly oil resistant, and their oil resistance was increased with an increase in coating w...

This work presents the formulation and characterization of a new product for protection outdoor frescoes from aggressive environmental agents. The is designed as an innovative green coating, prepared through zero-waste one-pot-synthetic method to form silver nanoparticles (AgNPs) directly in chitosan-based medium. AgNPs are seeded grown mixed hydrogel chitosan, azelaic, lactic acid, by reductio...

This study investigated the efficacy of co-deposited vancomycin/chitosan coatings prepared using a plasma process on metallic implants in bacterially challenged rabbit model. A BioDepTM coating was used to deposit thin layers chitosan with vancomycin onto titanium alloy surfaces. Coated were examined standard microscopy, profilometry and elution studies. Nitrided Ti-6Al-4V (Ti alloy) dynamic co...
