We have recently described the development of a printed cyanobacterial biobattery with potential application as a biodegradable power supply for low-power devices including biosensors and printed bioelectronics (Sawa M, Fantuzzi A, Bombelli P, Howe CJ, Hellgardt K & Nixon PJ (2017): Electricity generation from digitally printed cyanobacteria. Nature Commun. 8, 1327). The biobattery is conveniently fabricated by a scalable inkjet method to print both cyanobacterial cells and carbon nanotube electrode surfaces on which the cells grow as a biofilm. In the light, the printed device acts as a biophotovoltaic cell producing electrical current from electrons released from the cell during photosynthetic electron transport. Importantly, the biobattery can also produce electricity in the dark from the breakdown of stored products of photosynthesis, such as carbohydrate. The aim of this project is to improve the power output of the first-generation solar biobattery so that it can meet the power requirement for use in printed bioelectronics, as defined in collaboration with ARM PLC. Areas for investigation include the development of novel cyanobacterial strains (Nixon), the testing of novel electrode materials for improved conductance and biocompatibility (Shaffer), the development of robust printing techniques and composite design (Hellgardt) and the testing of devices in printed electronic devices (ARM PLC). Ultimately, we aim to fabricate a semi-living electronic device powered by sunlight using cyanobacterial cells - the 'solarbiochip'.

我们最近描述了印刷蓝藻生物电池的开发，该电池具有作为低功耗设备（包括生物传感器和印刷生物电子学）的可生物降解电源的潜在应用（Sawa M、Fantuzzi A、Bombelli P、Howe CJ、Hellgardt K 和 Nixon PJ (2017) ：数字印刷的蓝细菌发电。Nature Commun 8, 1327）。该生物电池可以通过可扩展的喷墨方法方便地制造，打印蓝藻细胞和碳纳米管电极表面，细胞在其上生长为生物膜。在光下，印刷设备充当生物光伏电池，在光合电子传输过程中利用电池释放的电子产生电流。重要的是，生物电池还可以在黑暗中通过分解储存的光合作用产物（例如碳水化合物）来发电。该项目的目的是提高第一代太阳能生物电池的功率输出，使其能够满足与 ARM PLC 合作定义的印刷生物电子产品的功率要求。研究领域包括新型蓝藻菌株的开发（Nixon）、测试新型电极材料以提高电导率和生物相容性（Shaffer）、开发稳健的印刷技术和复合材料设计（Hellgardt）以及印刷电子设备中的设备测试（ARM PLC）。最终，我们的目标是使用蓝藻细胞制造一种由阳光供电的半生命电子设备——“太阳能生物芯片”。
