Two novel scaffold models made of chitosan fibers were designed, fabricated, and investigated. Raw chitosan fibers were either tightened between plastic rings or were processed into stand-alone scaffolds. Chitosan fiber scaffolds were further modified by coating with a thin layer of fibrillar collagen type I to biologize the surface. Cell culture experiments were carried out using murine osteob...

Aim. The aim of this study was to investigate the antibacterial and antibiofilm properties of low viscosity chitosan on S. epidermidis growth and biofilm formation. Methods and Results. The antibacterial and antibiofilm properties were investigated, during both planktonic growth and biofilm formation. This was performed using different concentrations in media and by coating on polystyrene surfa...

Ferrite nanoparticles were synthesized at around 4°C~25°C and coated during the synthesis process with biocompatible and biodegradable polymers, dextran or chitosan. The size of ferrite nanoparticles was determined to be 7.51nm by DLS (Dynamic Light Scattering) and TEM (Transmission Electron Microscope). The size of coated nanoparticles was increased up to 128.6nm and 67nm for dextran and chito...

BACKGROUND A targeted drug nanoparticle (NP) delivery system has shown potential as a possible cancer treatment. Given its merits, such as its selective distribution at tumor sites and its controllable drug release, drug-loaded NPs can be effectively delivered to selected organs and targeted cells, thus enhancing its antitumor efficiency and reducing its toxicity. METHODS We reported that hya...

In the present study, the performance of chitosan coated carbon was evaluated for the removal of chromium (VI) and cadmium (II) from its aqueous solution. The chitosan coated carbon was prepared and characterized by using the various analytical tools such as FTIR, TGA, DSC and XRD. Batch adsorption experiments were performed in order to examine the effects of initial concentration, pH, and adso...

6 Common techniques to monitor the quality of fruit at the time of harvest and in storage typically rely on destructive methods to measure physical properties such as firmness and hydration. The complex, inhomogeneous composition of most fruit mean that non-destructive ultrasonic methods for quality evaluation of fruit has typically been unsuccessful. A novel ultrasound method was developed whi...
