Bio-templated syntheses of various nanomaterials have received increasing attention for functional applications. This approach is justified by the unique abilities of biological systems to guide sophisticated organization of molecules and materials into distinctive nano-morphologies that exhibit physicochemical properties highly desirable for specific purposes. Herein, we present a high-performance and flexible piezoelectric nanogenerator (NG) using anisotropic BaTiO3 nanocrystals synthesized on a M13 viral template through genetically programmed self-assembly of metal ion precursors. Even without the usage of additional structural stabilizers such as CNTs, our virus-enabled flexible NG exhibits a high electrical output up to ~ 300 nA and ~ 6 V by bending motion, which are two times higher than our previously reported NG. This work shows a new possibility of bio-templating approach as a facile method to design and fabricate nanostructures particularly suitable for energy harvesting. |
