Artificial antibacterial surfaces that are simple to fabricate

Nanotexturing to produce surfaces containing hydrophobic functionality was demonstrated with the production of plasma etched silicon (black silicon, bSi), chemically etched copper (black copper, bCu), and nano-wrinkled metal films formed on thermally relaxed, or shrunken plastic sheets. The features common to all of these surfaces high surface area, a surface structure resulting from self-organization and are surfaces that can be coated by metallic films using sputtering techniques. Such surfaces are applicable for sensor applications. The potential for applying these surfaces in anti-biofouling and hydrophobic applications is discussed.
