Abstract

Surfaces can be coated with photosensitizer molecules, which generate singlet oxygen (1O2) when the surface is exposed to light. 1O2 may diffuse from the coating and has the potential to kill microorganisms present on the surface. In the present study a derivative of the meso-tetraphenylporphyrin (TPP) was immobilized onto polyurethane (PU) after being sprayed and polymerized as a thin layer onto ...
