The electric-ionic conductivity, biocompatibility, and physicochemical properties of conducting materials are crucial subjects in the field of neural interface. In this study, we reported the nanostructured natural melanin composites with multifunctional properties and electrical conductivity, produced by two nanofabrication techniques: Layer-by-layer assembly (LBL) and depletion-attraction force assisted casting method. The LBL melanin coating possesses anti-inflammatory property and unique UV-visible light absorption with the structural colors. The depletion-force casted films of melanin NPs have shown well-ordered nanostructures with unconventionally high electrical conductivity. Experiments with Zophobos Morios larvae demonstrated their edibility and biocompatibility. These results showed the potential applications of our melanin composite films in the optoelectronic devices, implantable devices, and neural interfaces with unique electrical and biological properties. |
