Antimicrobial potential of bismuth lipophilic nanoparticles embedded into chitosan-based membrane

Fabrication of chitosan-hyaluronic acid nanoparticles and encapsulation into nanoparticles of dinitrosyl iron complexes as potential cardiological drugs

Objective(s): Currently, the development of nanoparticles for the stabilization and targeted delivery of cardiac drugs has gained significance. The present study aimed to develop nontoxic nanoparticles based on chitosan-hyaluronic acid (HA), encapsulate dinitrosyl iron complexes (DNICs, donors NO) into the nanoparticles to increase the stability and effectiveness of their action, and assess the...

Potential of bismuth nanoparticles embedded in a glass matrix for spectral-selective thermo-optical devices

Antimicrobial effect of chitosan nanoparticles on streptococcus mutans biofilms.

Nanoparticle complexes were prepared from chitosans of various molecular weights (MW) and degrees of deacetylation (DD). The antimicrobial effect was assessed by the Live/Dead BacLight technique in conjunction with confocal scanning laser microscopy (CSLM) and image analysis. Nanocomplexes prepared from chitosans with high MW showed a low antimicrobial effect (20 to 25% of cells damaged), where...

Nanoparticles of Chitosan Loaded Ciprofloxacin: Fabrication and Antimicrobial Activity

Purpose: Chitosan is a natural mucoadhesive polymer with antibacterial activity. In the present study, chitosan (CS) nanoparticles were investigated as a vehicle for delivery of antibiotic, ciprofloxacin hydrochloride. Methods: Ionotropic gelation method was used for preparation chitosan nanoparticles. The effects of various factors including concentration of CS, concentration of tripolyphospha...
