Research on Capitol Hill


With current demands for implantable electrical devices increasing, the need for a more stable and biocompatible source of power is becoming increasingly necessary. Several battery types and materials were evaluated. Ultimately, an abiotic biobattery was designed with the goal of implantation in the human body. Nafion, single-walled carbon nanotubes (SWCNTs), and gold were used to create an abiotic biobattery that is powered by glucose.

The SWCNTs were used to create the cathode, the gold was used to fabricate the anode, and the Nafion acted as the separator between the cathode and anode. A thin Nafion membrane was evaluated for overlaying the SWCNT cathode to prevent biofouling. A biofouling resistant membrane should allow the biobattery to continue to operate with greater efficiency without the surface area effectually decreasing over time as a result of biofouling.
