Melanin-based Organic-inorganic Structures for Sensor Application

Abstract

Melanin-silicon structures are promising organic-inorganic materials that combine the benefits of biopolymer and conventional semiconductors. In diode-like mode, the rectification factor is up to 500 and depends on melanin deposition time. Melanin-silicon structures could be used for glucose and volatile organic compounds vapors detection with sensitivity up to 18 mA/% and 0.23 A∙g/cm-3 respectively.
