Today, infectious diseases are the second leading cause of death globally, surpassed only by heart diseases. Traditionally, the most common strategies to mitigate disease-causing agents' spread are based on chemical disinfectants (such as bleach, hydrogen peroxide, and detergents) or repeated exposure to radiation (UV light). However, both approaches can damage the treated surface, adversely affect the environment, or introduce additional health concerns.
