Directed self-assembly of artificial amyloid proteins for supramolecular electronic applications


Published on 2 February 2018



Abstract
A major challenge in nanotechnology is bottom-up manufacturing of useful devices and materials via self-assembly at room temperature in environmentally benign solvents. Biological systems provide numerous examples of self-organisation of in aqueous environment in the guise of protein structures such as microtubules, viral capsids, and amyloid fibrils. The latter are self-assembled supramolecular polymers possessing extraordinary chemical and physical properties (high structural regularity, high persistence length, intrinsic photoluminescence…). This project endeavors to use artificial amyloid proteins as building blocks for the rational design of functional nano-filaments suitable for various (opto)electronic applications. Supramolecular polymerization of the starting proteins will be investigated both in homogenous solution and on solids supports - such electrodes or semi-conductor chips - previously decorated by nanolithography. The resulting nano-filaments will then be characterized to elucidate their structure, morphology, connectivity and (photo)electronic behavior.
