Abstract: Disclosed herein is a healthcare system and method for analyzing a biological sample having a data acquisition unit, a field unit for obtaining and storing visualized biomarkers; an optical lens adapter configured to adapt to an imaging device capable of taking images of the visualized biomarkers; a data analysis unit having an analyzing unit to receive and evaluate the image to determine the presence or absence of preset values that are above or below an arbitrarily set threshold level; and an output device providing a graphic or textual output according to the presence or absence of the preset values.

Abstract: An array of electrodes for use in a flat panel display includes a plurality of electron emitters formed of polycrystalline or single crystalline silicon which has been selectively etched to form pores in the emitters. The electrode array is then electroplated in a methane plasma to deposit a carbon compound such as silicon carbide on the surfaces of the emitters and in the pores of the emitters. Each emitter has a generally flat electron emitting surface which facilitates a longer life for the electrode array, the porous structure of the emitters increasing the electron emission efficiency of the emitters in relatively low electric fields. The electrode array can be integral with a support substrate by anisotropically etching the substrate to form the emitters. A layered interconnect structure can be formed on a surface of the silicon substrate for providing the interconnect structure for the electrode array.
