Final Report - DREAMS (Diamond to retina artificial micro-interface structures)

Project ID: 33345
Funded under: FP6-NMP

Abstract

Currently available commercial devices are based on metallised electrodes which are degraded in a physiological environment and induce reactive gliosis leading to insulating interfaces. The high resolution required for vision and the stimulation of graded potential neurons requires the use of complex and very precise stimulators capable of generating signals of varying intensity. Recent progress in nanotechnologies and their application for biology have motivated the emergence of new interfacing concepts for direct communication between biological and electronics.

DREAMS proposed to study and fabricate novel types of nanotransducers, which are based on artificial nanocrystalline diamond (NCD). Their final report describes how the project partners studied and fabricated these novel types of nanotransducers, which are based on synthetic NCD and epitaxial single crystal CVD diamond thin films. The key objectives of the project were to take advantage of both the biocompatibility and the semiconducting properties of diamond in order to explore the feasibility of fabrication of novel artificial retina implants.
