In the field of organic thin film transistor, many organic or polymeric semiconductors has been introduced for an application of biocompatible electronics. Recently, indigo and its derivatives materials, which are natural pigments, have been continuously adopted for biosemiconductor applications. In addition, melanin also has been steadily reported as a biomaterial-based conductor. Here, in this study, a new biosemiconductor or biopolymer material synthesized by recombinant DNA based Escherichia coli was produced with a combination of indigo and melanin, which was named as melanindigo. Electrical properties and serveral bandgap analysis demonstrated that the Melanindigo have semiconductic behavior. Through this research, it was possible to confirm the feasibility of a new biosemiconductor made from eco-friendly synthesis rather than artificial synthesis. Futhermore, the melanindigo will be a biocompatible or implantable material that can be used as wearable and implantable TFT. |
