Self-assembled glycol chitosan nanoparticles for disease-specific theranostics

Area of Science:

• Biomaterials Science
• Nanotechnology
• Drug Delivery Systems

Background:

• Glycol chitosan nanoparticles (CNPs) are self-assembled structures with extensive research history.
• Hydrophobically modified glycol chitosan (hGC) forms nanoparticles (NPs) in aqueous conditions.
• CNPs possess excellent physiochemical and biological properties for biomedical applications.

Purpose of the Study:

• To review the research progress of CNPs in theranostics.
• To discuss current challenges and future opportunities for CNPs in disease diagnosis and personalized medicine.
• To highlight the potential of CNPs as a dual-purpose delivery system for imaging agents and therapeutics.

Main Methods:

• Self-assembly of hydrophobically modified glycol chitosan (hGC) into nanoparticles (NPs).
• Modification of CNPs with imaging agents and encapsulation of various therapeutic agents (chemo-drugs, nucleotides, peptides, photodynamic chemicals).
• Evaluation of CNPs for multimodal imaging and targeted drug delivery in in vivo conditions.

Main Results:

• CNPs can be simply modified for disease-specific theranostics.
• Hydrophobic domains of hGC facilitate drug encapsulation via hydrophobic or charge-charge interactions.
• Successful in vivo delivery of encapsulated imaging agents and therapeutics to targeted diseases has been demonstrated.

Conclusions:

• CNPs show great potential as an efficient theranostic system for simultaneous imaging and therapeutic delivery.
• Overcoming current challenges will enhance CNP applications in early disease diagnosis and personalized medicine.
• Continued research on CNPs is crucial for advancing theranostic capabilities.
