Abstract (EN)

Biotemplating of nanoelectronic structures is emerging as one of the most promising strategies for advancing the self-assembly of nanoscale electronic components, driven by the need to overcome scaling costs and energy demands in modern semiconductor fabrication while increasing circuit complexity. In this realm, DNA origami and microtubules provide attractive platforms that combine small dimensions with structural rigidity, enabling precise nanoscale fabrication of metallic components. Here, we demonstrate that nanoparticle-hybridized biotemplates can be electroless reduced to yield metallic nanowires and, in an alternative way, can be manipulated via dielectrophoresis to form highly conductive metallic structures. A millisecond scale field-induced pulses trigger atomic-scale rearrangements, revealing a novel resistive switching mechanism to encode logical states. In addition, a novel dielectrophoretic assembly process, termed fusion mechanism, drives the formation of Au wires that maintain a consistent low resistance (161 Ω) independent of length over micrometer scales. These findings report advances in supracolloidal structures, demonstrating how structural dynamics within quasi-1D metallic lattices can be engineered to program electronic functionality. By combining biotemplated precision with field-tunable reconfigurability, this work establishes a blueprint for solution-processed, reconfigurable and self-organized nanoelectronic interconnectors for the next-generation of information processing technologies.
