The present work reports on enzyme attachment on and photoinduced release from TiO$_2$ surfaces. TiO$_2$ layers (amorphous and anatase) were modified with 3-aminopropyltriethoxysilane (APTES), followed by attachment of vitamin C and horseradish peroxidase (HRP). Using step by step XPS characterization and vis-spectroscopy we show that upon UV illumination the linker chain to the protein can be cut, releasing active HRP into the environment. The head silane group remains attached to the TiO$_2$ surface. The kinetics of this photoinduced release is significantly faster for the anatase form of TiO$_2$ compared with amorphous material. The results indicate that UV induced chain scission represents a very versatile tool for payload release from TiO$_2$ surfaces.
