Advanced health informatics is a grand challenge for 21st century medicine. The aim is to develop devices to enhance personalised healthcare. Part of such devices is selecting materials that can interface between biology and computers, i.e. bioelectronics. One promising material is the skin pigment melanin, since it is bio-compatible and sustains electrical current. Recently we performed a series of electrical measurements on melanin that apparently confirms the dominance of redox chemistry in driving its electrical current. However, we need to confirm our observations with an independent technique. Muon spin resonance provides the ideal alternative. The key objective is to obtain (as a function of hydration, chemical energy and temperature) muon relaxation rate behaviour and correlate it to our result. This should then open the muSR technique to a new user base in bioelectronics.
