Disclosed is a method of forming a conductive diamond layer on a surface of a carbon fibre substrate that is used as a component of an electrode for neural stimulation and/or electrochemical sensing. The method comprises functionalising at least a portion of the surface with a functionalising agent to facilitate coating the surface with the conductive diamond layer. The method also comprises providing a diamond precursor and depositing the diamond precursor over the functionalising agent to form the conductive diamond layer. The disclosure also relates to an electrode that is used as a component of an electrode for neural stimulation and/or electrochemical sensing.

The present disclosure provides a method of forming a hermetically sealed enclosure that comprises a diamond material. The method comprises providing first and second enclosure components comprising the diamond material and having first and second recesses, respectively, at edge portions. At least one of the first and second enclosure components has a cavity. The enclosure components have respective contact surfaces at the first and second recesses and are shaped such that an outer channel is formed by the co-operation of the first and second recesses when the first and second enclosure components are contacted at the contact surfaces to form the enclosure. The method further comprises bonding a first type of material to at least surface portions of the first and second recesses of the first and second enclosure components, respectively. The method also comprises bonding a second type of material to the first type of material so that the second type of material covers at least portions of the first type of material. The second type of material is biocompatible and suitable for forming a hermetically sealed seal. In addition, the method comprises contacting the enclosure components to form the enclosure and bonding the second type of material of the first enclosure component to the second type of material of the second enclosure component so as to form a hermetically sealed seal in the outer channel.

The present disclosure provides a method of fabricating a diamond membrane. The method comprises providing a substrate and a support structure. The substrate comprises a diamond material having a first surface and the substrate further comprises a sub-surface layer that is positioned below the first surface and has a crystallographic structure that is different to that of the diamond material. The sub-surface layer is positioned to divide the diamond material into first and second regions wherein the first region is positioned between the first surface and the sub-surface layer. The support structure also comprises a diamond material and is connected to, and covers a portion of, the first surface of the substrate. The method further comprises selectively removing the second region of the diamond material from the substrate by etching away at least a portion of the sub-surface layer of the substrate.
