Understanding the Impact of Retraction on Scientific Progress: A Case Study on Silver Nanoparticles

Abstract

Silver has long been recognized for its potent antibacterial properties and its extensive use in healthcare applications over the years. Its integration into medical devices, particularly those requiring antibacterial capabilities for optimal functionality, holds significant promise. Research indicates that silver exhibits much higher toxicity against bacteria than against human cells, making it an attractive material for biomedical applications. Silver nanoparticles, which range in size from 1 to 100 nanometers, possess unique physical and chemical properties that make them valuable in molecular diagnostics, therapeutic applications, and medical devices. However, traditional methods of synthesizing these nanoparticles, such as chemical and physical approaches, are often complex and may result in the absorption of toxic substances on the nanoparticle surfaces. To overcome these challenges, biological synthesis methods have emerged as a safer and more sustainable alternative, utilizing bacteria, fungi, and plant extracts as primary agents in the production process. This paper provides a comprehensive review of the mechanisms, synthesis methods, and medical applications of silver nanoparticles. It also addresses the environmental and health-related concerns associated with their use. Special focus is given to optimizing the synthesis process to ensure efficiency and safety while evaluating their potential applications and exploring ongoing debates surrounding their toxicity and environmental impact.
