摘要

Coating is uniquely feasible means to impart biocompatibility to artificial materials to be used in biology and medicine, because a totally different surface-state could be created. However, it is necessary to understand factors that control 鈥渂iocompatibility鈥?first. The examination of molecular level factors involved in interfacial interaction revealed that the best surface-state for biocompatibility should contain no chemical functional group. Such a surface-state cannot be created by conventional chemical means, and application of conventional coating could be used in rather limited cases only. Magneto-luminous polymerization of methane yields nanofilm of amorphous carbon, which seems to be the closest to the ideal non-interacting surface. Fundamental factors involved in interactions of polymer surface with surrounding medium, and mechanisms how magneto-luminous polymerization coating yields amorphous carbon nanofilm, which has the least interfacial interaction capability, are described in this paper.
