Pharmaceutical aspects of silver nanoparticles

Area of Science:

• Nanotechnology
• Materials Science
• Biomedical Engineering

Background:

• Silver nanoparticles (AgNPs) are crucial in medicine, but traditional synthesis methods are costly and toxic.
• Biological synthesis offers an eco-friendly and less toxic alternative using natural sources.
• AgNPs exhibit significant antimicrobial properties alongside diagnostic and therapeutic potential.

Purpose of the Study:

• To provide a comprehensive overview of silver nanoparticle synthesis, applications, and toxicological challenges.
• To highlight the advantages of biological synthesis methods for AgNPs.
• To review the diverse biomedical applications of AgNPs.

Main Methods:

• Literature review of synthesis methods (physical, chemical, biological).
• Analysis of AgNP applications in diagnostics, therapeutics, and antimicrobial strategies.
• Examination of AgNP pharmacokinetics and formulations.
• Assessment of toxicological data and challenges.

Main Results:

• Biological synthesis is a cost-effective, environmentally benign, and less toxic route for AgNPs.
• AgNPs demonstrate broad-spectrum antimicrobial activity and are effective in treating infections.
• Applications span diagnostics, drug delivery, wound healing, cancer therapy, and infertility management.
• Nanotoxicity and potential adverse effects require careful consideration.

Conclusions:

• Silver nanoparticles hold immense promise for biomedical applications, particularly when synthesized biologically.
• Further research is needed to optimize AgNP formulations and fully understand their long-term toxicological profiles.
• Balancing therapeutic benefits with potential risks is essential for clinical translation.
