The main aim of this research work was to develop controlled drug delivery systems based on nanotechnology. Chitosan nanoparticles (CSNPs) were selected as a nanocarrier for the selected antibiotic drugs tetracycline, gentamycin and ciprofloxacin. CSNPs were prepared from chitosan solution by using tripolyphosphate (TPP) via ionic gelation method. Then the prepared high performance CSNPs were loaded with three different antibiotics to form nanocomposite from antibiotic loaded chitosan nanoparticles. Then the prepared nanocomposite used as superior antibacterial materials with minimum toxicity. Samples of cotton (100%) and (50:50) cotton/polyester blended fabrics were treated with different concentrations of this composite to impart antibacterial activity. Results showed that the treated fabrics with chitosan nanoparticles and its nanocomposite with different antibiotics were inhibited the growth of both Gram-positive and Gram-negative bacteria. The Fourier Transform Infrared spectroscopy (FTIR) and Scanning Electron Microscope (SEM) analysis exposed the embedding of chitosan nanoparticles into fabrics and their antibiotics loaded.

This study aimed to examine how mesoporous silica nanoparticles-chitosan-folic acid impacted the release of recombinant Azurin within the tumor environment. The goal was to trigger apoptosis and stimulate immune responses against both transformed and normal cells in BALB/c mice. The study found that the use of rAzu-MSNs-CS-FA, a specific formulation containing mesoporous silica nanoparticles-chitosan-folic acid, resulted in pH-responsive behavior and slower release of rAzurin compared to other groups.

Chitosan salicylaldehyde/calcium oxide nanoparticle (CS-SL/CaO) was synthesized by hydrothermal process and isolated via different drying processes, namely, air-drying (AD) and freeze-drying (FD). The physicochemical properties of freeze-dried CS-SL/CaO nanoparticle (CS-SL/CaO-FD) and air-dried CS-SL/CaO nanoparticle (CS-SL/CaO-AD) were compared. In particular, the adsorption properties reveal that the specific surface area of CS-SL/CaO-FD increased by ca.

Vitamin B, or riboflavin, is essential for maintaining healthy cellular metabolism and function. However, its light sensitivity, poor water solubility, and gastrointestinal barriers limit its storage, delivery, and absorption. Selecting suitable nanomaterials for encapsulating vitamin B is crucial to overcoming these challenges.
