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.

Nanopillars, Nanowires and Nanoballs for DNA and Protein Analysis

2016
Recent development of nanofluidic devices using nanopillars, nanowires, and nanoballs for high-performance biomolecules analysis are reviewed in this chapter. Two approaches, “top-down” fabrication techniques and “bottom-up” self-assemble techniques, were applied to construct nanospace inside microchannels, and various biomolecules including DNA, RNA ...

Protein Recognition via Surface Molecularly Imprinted Polymer Nanowires

Analytical Chemistry, 2005
In this paper, we present a technique for the preparation of polymer nanowires with the protein molecule imprinted and binding sites at surface. These surface imprinting nanowires exhibit highly selective recognition for a variety of template proteins, including albumin, hemoglobin, and cytochrome c.

Proteins and Peptides as Biological Nanowires: Towards Biosensing Devices

2013
The current landscape of nanotechnology is such that attention is being given to those materials that self-assemble, as a mode of "bottom-up" fabrication of nanomaterials. The field of nanotubes and nanowires has long been dominated by carbon nanotubes and inorganic materials.

Electron microscopy imaging of proteins on gallium phosphide semiconductor nanowires

Nanoscale, 2016
We have imaged GaP nanowires (NWs) incubated with human laminin, serum albumin (HSA), and blood plasma using both cryo-transmission electron microscopy and synchrotron based X-ray photoemission electron microscopy. This extensive imaging methodology simultaneously reveals structural, chemical and morphological details of individual nanowires and the ...
