Chitosan magnetic nanoparticles for drug delivery systems

Area of Science:

• Biomaterials Science
• Nanotechnology
• Drug Delivery Systems

Background:

• Magnetic nanoparticles (MNPs) are valuable for drug delivery systems (DDSs) due to their magnetic core and functional surface coatings.
• Surface coatings on MNPs prevent aggregation under physiological conditions and allow for bioconjugation with drugs and targeting ligands.
• Chitosan, a natural biopolymer, offers reactive functional groups and forms nanoparticles (NPs) with enhanced properties.

Purpose of the Study:

• To review the current applications of magnetic chitosan nanoparticles in drug delivery systems (DDSs).
• To investigate the challenges and limitations hindering the widespread use of these nanoparticles.
• To provide insights into future research and commercialization strategies for magnetic chitosan NPs in DDSs.

Main Methods:

• Literature review of existing research on magnetic chitosan nanoparticles for drug delivery.
• Analysis of the physico-chemical, antimicrobial, and biological properties of chitosan NPs.
• Evaluation of functionalization strategies for bioconjugation and targeting.

Main Results:

• Chitosan nanoparticles exhibit superior properties compared to bulk chitosan, making them ideal for DDSs.
• Magnetic chitosan NPs demonstrate potential for controlled drug release and targeted delivery.
