Micro-patterned biological interfaces manufactured by diamond turning with CVD diamond micro-tools

The generation of microstructured interfaces which enhance cell adhesion and proliferation is of great interest in bioremediation, i.e. in all those applications where biological reactions result in the destruction of contaminants. Diamond turning has been implemented for the manufacture of microstructures, taking advantage of bespoke CVD diamond micro-tools in which the edge profile was successfully modified using a combined laser/FIB machining strategy. The CVD micro-tools show good cutting performance in terms of the achievable cutting volume and repeatability of the fabricatedmicrostructure.
