Disclosed is a coating with reversible wettability, the coating having a hydrophobic state wherein the anti-pathogen coating has a hydrophobic surface that repels at least one of bacteria, fungi, and viruses; and a hydrophilic state wherein the anti-pathogen coating has a hydrophilic surface that inactivates at least one of bacteria, fungi, and viruses, wherein the hydrophobic state switchable to the hydrophilic state by exposure to a first switching stimulus and the hydrophilic state switchable to the hydrophobic state by exposure to a second switching stimulus. This reversible wettability switch between superhydrophobicity and superhydrophilicity can be repeated at least three times, which indicating the process for controlled repellent or inactivation of bacteria, fungi, or viruses can be converted at least three times.

An improved technology for inactivation of viruses, for example the SARS-CoV-2 virus that is causing the Covid-19 pandemic, is described. The technology can include a device that includes a substrate coated in a polymer that is infused with a pathogen inactivating material. In various embodiments, at a given time, a portion of the pathogen inactivating material is exposed to the environment, and the device is configured to periodically or intermittently expose additional pathogen inactivating material to the environment. For example, the polymer can be ablative or sacrificial.
