Synthetic Biological Protein Nanowires with High Conductivity

Small, 2016
Genetic modification to add tryptophan to PilA, the monomer for the electrically conductive pili of Geobacter sulfurreducens, yields conductive protein filaments 2000-fold more conductive than the wild-type pili while cutting the diameter in half to 1.5 nm.

Customization of Protein Single Nanowires for Optical Biosensing

Small, 2015
An all-protein single-nanowire optical biosensor is constructed by a facile and general femtosecond laser direct writing approach with nanoscale structural customization. As-formed protein single nanowires show excellent optical properties (fine waveguiding performance and bio-applicable transmission windows), and are utilized as evanescent optical ...

Attenuation of Protein Adsorption on Static and Oscillating Magnetostrictive Nanowires

Nano Letters, 2005
The research described here investigates the hypothesis that nanoarchitecture contained in a nanowire array is capable of attenuating the adverse host response generated when medical devices are implanted in the body. This adverse host response, or biofouling, generates an avascular fibrous mass transfer barrier between the device and the analyte of ...

One‐Dimensional Magnetic Nanowires Obtained by Protein Fibril Biotemplating

Chemistry - A European Journal, 2011
AbstractMagnetic nanowires were obtained through the in situ synthesis of magnetic material by Fe‐controlled nanoprecipitation in the presence of two different protein (human serum albumin (HSA) and lysozyme (Lys)) fibrils as biotemplating agents. The structural characteristics of the biotemplates were transferred to the hybrid magnetic wires.

Optical Regulation of Protein Adsorption and Cell Adhesion by Photoresponsive GaN Nanowires

ACS Applied Materials & Interfaces, 2013
Interfacing nanowires with living cells is attracting more and more interest due to the potential applications, such as cell culture engineering and drug delivery. We report on the feasibility of using photoresponsive semiconductor gallium nitride (GaN) nanowires (NWs) for regulating the behaviors of biomolecules and cells at the nano/biointerface. The

Metallic nanowires on a new protein template

SPIE Proceedings, 2007
Exploiting the concepts learnt from nature to build new nanomaterials from the bottom-up is critical for the efficient design of complex nanodevices. We demonstrate for the first time that the capacity of the a-synuclein protein to assemble into nanofibers can be used for the synthesis of metallic nanowires.
