Antimicrobial stewardship for the outpatient pediatric provider

Area of Science:

• Biomedical Engineering
• Materials Science

Background:

• Drug delivery systems are crucial for therapeutic efficacy.
• Current methods face challenges in targeted delivery and bioavailability.
• Nanotechnology offers potential solutions for overcoming these limitations.

Purpose of the Study:

• To develop and characterize a novel nanoparticle-based drug delivery system.
• To evaluate the in vitro and in vivo performance of the developed system.
• To assess the potential of this system for targeted cancer therapy.

Main Methods:

• Synthesis and characterization of poly(lactic-co-glycolic acid) (PLGA) nanoparticles.
• Encapsulation of doxorubicin (DOX) within the nanoparticles.
• In vitro drug release studies and cell viability assays using MCF-7 breast cancer cells.
• In vivo biodistribution and efficacy studies in a murine xenograft model.

Main Results:

• Successfully synthesized and characterized DOX-loaded PLGA nanoparticles with controlled release kinetics.
• Demonstrated significant in vitro cytotoxicity against MCF-7 cells compared to free DOX.
• Achieved enhanced tumor accumulation and prolonged circulation time in vivo.
• Observed significant tumor growth inhibition and improved survival rates in the animal model.

Conclusions:

• The developed PLGA nanoparticle system is a promising platform for targeted drug delivery.
• This system enhances therapeutic efficacy and reduces systemic toxicity.
• Further investigation is warranted for clinical translation in cancer treatment.
