摘要

Semiconductors are one of the most versatile materials found today and are applied in various fields of technology. Currently, one of the applications gaining significant recognition is their use as antimicrobial agents. Unlike other organic antimicrobial agents like antibiotics and antifungal drugs, semiconductors have different mechanisms of action. Silver (Ag) has been prominent since ancient times due to its ability for ionic release, interaction with organic groups based on phosphorus and sulfur, and plasmonic effect among the primary materials used for microbial elimination. As a result, not only Ag-based nanoparticles are highly efficient in inactivating pathogens, but also Ag-based semiconductors are extensively utilized for this purpose. This work focuses on studying the design of Ag-based semiconductors, including Ag2O, AgVO3, Ag2WO4, Ag2CrO4, Ag2MoO4, and Ag3PO4, along with their intrinsic antimicrobial activity. Additionally, it explores new perspectives and future trends in applying these materials.
