| Abstract Scope |
Diamond thin films such as nanocrytalline diamond and ultrananocrystalline diamond thin films are finding greater use in prostheses and other biomedical devices. Diamond thin films exhibit exceptional biomedical properties, including chemical inertness and wear resistance. In addition, the conductivity of diamond thin films can be altered through the incorporation of nitrogen. Ultrananocrystalline diamond-coated microneedles have been evaluated for electrochemical sensing, and nanoporous membranes have been examined for neural interface applications. We have previously demonstrated electrochemical detection of uric acid and dopamine under in vitro conditions with unmodified N-UNCD microneedles. We have also previously created free-standing nanoporous ultrananocrystalline diamond membranes with pore sizes of 100 nm by growing ultrananocrystalline diamond thin films on nanoporous silicon nitride membranes and reactive ion etching; the attachment of SK-N-SH cells on the membrane features was demonstrated. Our results suggest that diamond thin films exhibit many unique attributes that many enhance the function of medical devices.
