Nanostructured antibacterial surfaces – What can be achieved?

Nanomaterials have emerged as the new weapon in the arsenal to fight antimicrobial resistance (AMR). While antibiotics have played a major role in combating infectious diseases, AMR presents a new challenge for sustainability in global health, food security and development. Inspired by nature, recent trending research has demonstrated that specific nanoscale surface patterns can rupture and kill bacteria on contact. Nano-engineered surfaces have demonstrated good capacity to prevent bacterial attachment and biofilm formation (the precursor to infection) and could be used as a strategic disinfectant for medically and industrially relevant materials. This opinion paper provides an overview of the role of nanotechnologies, specifically nanostructured surfaces, in aiding the development of infection-resistant surfaces.
