“…Степенью гибридизации углерода в пленках можно управлять, меняя условия осаждения. В частности, в работе [5] показано, что увеличение доли Ne в составе распыляющего газа при импульсном магнетронном напылении композитных пленок DLC приводит к увеличению доли sp 3 -фракции углерода, наряду с увеличением твердости и износостойкости полученных покрытий. В работе [6] при получении негидрированного алмазоподобного углерода варьировалось напряжение смещения в процессе напыления.…”

In the treatment of kidney diseases such as chronic kidney disease (CKD) and acute tubular necrosis (ATN), prolonged contact between conductivity sensors and patients' bodily fluids is required, necessitating high biocompatibility for the electrodes. However, the widely used graphite electrodes exhibit limited biocompatibility, showing a cell survival rate of only 88% under indirect contact conditions, and <56% under direct contact conditions. Here, the surface detachment of graphite electrodes in liquid environments leading to cell death upon contact is observed and a solution is proposed to enhance biocompatibility and ensure conductivity, by forming a layer of interface‐stable coating (ISC) as a conductive isolation membrane on their surface. For applications with contact requirements, graphite‐like carbon (GLC) coated graphite electrodes are investigated and developed, resulting in an exceptional cell survival rate exceeding 96% under indirect contact conditions, and a relatively high survival rate exceeding 91% under direct contact conditions, both accompanied by significant proliferation. GLC‐coated graphite electrodes are successfully to monitor the dialysate conductivity in a hemodialysis machine and achieve stable monitoring with temperature compensation. The results demonstrate ISC graphite electrodes' potential in biomedical fluid monitoring, with the developed process applicable to other fields.

Multilayer films of diamond‐like carbon (DLC) on monocrystalline diamond substrates have been for the first time obtained by plasma‐chemical deposition. Their chemical composition and structural and morphological properties are studied. The DLC individual layers differ in their sp3 carbon content. The multilayer nature of the resulting coatings is confirmed by periodic density modulation on the small‐angle X‐ray reflectometry curve and modulations in the CsC8, CsC6, CsC4 lines on the crater depth profile of secondary ions of elements (secondary ion mass spectrometry). The dependence of the deposition rate of multilayer DLC films on diamond, their composition and properties on the argon additive to the reaction gas mixture, as well as on methane flow, pressure and growth time, are studied.
