Piezoelectric nanomaterials for antibacterial strategies

In contemporary times, bacteria and their escalating antibiotic resistance present a formidable global menace, rendering conventional antibiotic therapies futile. This phenomenon not only complicates the management of infectious diseases but also exacerbates healthcare expenditures, potentially culminating in grave ramifications. This review delves into the intricate realm of the antibacterial mechanism and biomedical utility of emerging nanoscale piezoelectric antibiotics. It commences by elucidating the distinctive piezoelectric effect inherent in nanomaterials. Subsequently, it meticulously categorizes piezoelectric nanomaterials into discrete classifications, encompassing single-crystal, polycrystalline, transition metal dichalcogenides (TMDCs), polymer, and composite iterations.
