“…On contrast to other authors, who highlight for successful NSCs attachment on diamond, the organic copolymer necessity [26,27], in our case no additional coating was employed. The explanation of this issue could be applying of suitable culture medium that, as in case of Refs.…”

Phone: þ420 220 318 482, Fax: þ420 220 318 468A controllable growth of neural cells and/or neural stem cells (NSCs) on artificial substrates is highly attractive scientifically as motivated by neurological and neurodegenerative disease treatment. In this contribution, we report on human fetal NSCs attachment and growth on the diamond films. Diamond films of different morphologies were deposited by linear antenna microwave plasma system from H 2 /CO 2 /CH 4 gas mixtures.We show that the employed NSC lines attach to the oxidized diamond surface rather than hydrogenated. The influences of nanocrystalline diamond morphology (flat film, porous structure, or nano-rods) and surface treatment (oxidized/ hydrogenated or laminin coated films) are systematically studied after 8-day cells seeding.

“…Hence, more robust and more biocompatible thin film materials are sought in order to induce neither immune response in tissue nor degradation over time. In this context, conductive diamond is seen as a promising electrode material because it is physically and chemically highly stable as well as biocompatible and reduced glial formation has been observed when compared with other electrode materials, thus promoting long term stability of the neural stimulation [8][9][10][11][12][13]. Also, diamond offers a quality interface with biological tissues since the development of neurons and glial cells on diamond was proven to be comparable to the one on glass substrate [14].…”

Neuron Adhesion on Diamond: Competition between Polymer Treatment and Surface Morphology

et al. 2018

The ability to form an efficient interface between material and neural cells is a crucial aspect of the construction of neuroelectrodes. Diamond offers material characteristics that could, by a large extent, improve the performance of neuroelectrodes. The greatest advantage of diamond is a large variety of material and surface properties such as electrical conductivity, surface morphology, and surface chemistry. Such a variety of material characteristics can lead to various cellular responses. Here we compare survival, adhesion, and neurite formation of primary neurons on diamond thin films of various morphology and on their treatment with several types of polymers commonly used to enhance cell adhesion. We found that the variation of surface roughness of nanocrystalline diamond film does not have a major influence on the neuron survival or adhesion. The adhesion of neurons can beinfluenced by the selected type of polymer coating.
