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

DNA-templated Assembly of Nanowires and Protein-functionalized Nanocontacts

Supramolecular Chemistry, 2005
We describe the use of DNA to template the assembly of gold nanowires between conventionally patterned gold contacts on a silicon wafer substrate. We also describe the use of DNA to template the assembly of protein-functionalized gold nanocontacts on a silicon wafer substrate.

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.

Surface molecularly imprinted nanowire for protein specific recognition

Chemical Communications, 2008
A surface molecularly imprinted nanowire is designed by chemical polymerization of dopamine in neutral aqueous solution, which shows high binding capacity and acceptable specific recognition behavior towards template proteins.

Bioelectronic protein nanowire sensors for ammonia detection

Nano Research, 2020
Electronic sensors based on biomaterials can lead to novel green technologies that are low cost, renewable, and eco-friendly. Here we demonstrate bioelectronic ammonia sensors made from protein nanowires harvested from the microorganism Geobacter sulfurreducens.

Deformation behavior and mechanical properties of amyloid protein nanowires

Journal of the Mechanical Behavior of Biomedical Materials, 2013
Amyloid fibrils are most often associated with their pathological role in diseases like Alzheimer's disease and Parkinson's disease, but they are now increasingly being considered for uses in functional engineering materials. They are among the stiffest protein fibers known but they are also rather brittle, and it is unclear how this combination of ...

Immobilization of proteins on semiconductor nanowires for biosensor development

2011 International Semiconductor Device Research Symposium (ISDRS), 2011
Silicon (Si), silicon carbide (SiC), gallium nitride (GaN), zinc oxide (ZnO) and other semiconductor nanowires (NWs) show great promise as sensing elements for the electrical detection of biomolecules [1–3]. In order to enable chemiresistor-type NW devices that utilize direct electronic sensing of biomolecules, one must first develop an analyte ...

Power generation from ambient humidity using protein nanowires

Nature, 2020
Harvesting energy from the environment offers the promise of clean power for self-sustained systems1,2. Known technologies-such as solar cells, thermoelectric devices and mechanical generators-have specific environmental requirements that restrict where they can be deployed and limit their potential for continuous energy production3-5.

Electrochemical Template Synthesis of Multisegment Nanowires:  Fabrication and Protein Functionalization

Langmuir, 2006
Multisegment nanowires represent a unique platform for engineering multifunctional nanoparticles for a wide range of applications. For example, the optical and magnetic properties of nanowires can be tailored by modifying the size, shape, and composition of each segment.
