This work compares the impact of molecular functionalization and selected material properties of diamond thin films on the growth of neurons. The ability to form an efficient interface between material and neural cells is a crucial aspect of the construction of neuroelectrodes. Diamond thin films offer material characteristics that could greatly improve the performance of neuroelectrodes. The advantage of diamond is a large variety of material and surface properties. Such a variety of material characteristics can lead to various cellular responses. Here we compare growth and development of primary neural cells on diamond thin films of various morphology, conductivity, and doping with their treatment using several types of molecules commonly used to enhance adhesion and cell growth. We found that the variation of material properties of nanocrystalline diamond film does not have a major influence on the neuron growth but it can be to, some extent, influenced by the type of molecular coating, selection of polymer and its molecular weight. Our findings emphasize the importance of the correct molecular treatment over structural or morphological properties of diamond thin films as a material used to form an interface with primary neurons.
