Localized, on-demand, sustained drug delivery from biopolymer-based materials.

Area of Science:

• Biomaterials Science
• Drug Delivery Systems
• Nanotechnology

Background:

• Local drug delivery enhances therapeutic efficacy and minimizes systemic toxicity by achieving higher drug concentrations at the target site.
• Existing local drug delivery systems encounter challenges in drug encapsulation, controlled release, and efficient therapeutic delivery.
• Naturally derived biopolymers present a promising alternative for advanced drug delivery applications.

Purpose of the Study:

• To provide an overview of naturally derived biopolymer-based drug delivery systems for localized, sustained, and on-demand treatment.
• To discuss the advantages and limitations of these biopolymer systems in drug encapsulation, delivery, and local release.
• To highlight recent applications and future directions in biopolymer-based drug delivery.

Main Methods:

• Review of literature on naturally derived biopolymers for drug delivery.
• Analysis of properties such as biocompatibility, biodegradability, and processability of biopolymers.
• Examination of applications and challenges in biopolymer-based drug encapsulation, delivery, and controlled release.

Main Results:

• Naturally derived biopolymers (e.g., cellulose, chitosan, alginate) are suitable for local drug delivery due to their chemical modifiability, biocompatibility, and biodegradability.
• These biopolymers can be processed in aqueous environments, preserving therapeutic bioactivity.
• Balancing therapeutic dosage and local tissue response is crucial in designing these systems.

Conclusions:

• Naturally derived biopolymers offer significant advantages for localized drug delivery systems.
• Future research should focus on tunable biodegradation rates and commercial viability for replacing synthetic polymers.
• Biopolymer-based systems hold potential for improved therapeutic outcomes and reduced side effects.
