An antibody-functionalized gold nanorod array enables the realization of a reusable early-warning system for detecting harmful pathogens dispersed in drinkable water.

BACKGROUND AND METHODS Various methods have been used to modify titanium implant surfaces with the aim of achieving better osseointegration. In this study, we fabricated a clustered nanorod structure on an acid-etched, microstructured titanium plate surface using hydrogen peroxide. We also evaluated biofunctionalization of the hybrid micro/nanorod topography on rat bone marrow mesenchymal stem ...

An amperometric biosensor was constructed by using ZnO nanorod clusters as platforms for immobilizing tyrosinase on the nanocrystalline diamond (NCD) electrodes. The results showed that ZnO nanorod clusters provided an advantageous microenvironment due to their favorable isoelectric point (IEP) for tyrosinase loading; immobilized tyrosinase generally retained its activity. The tyrosinase/ZnO/NC...

Uniform GaN nanorod arrays are grown vertically by selective area growth on (left angle bracket 0001 right angle bracket) substrates. The GaN nanorods present six nonpolar {1⁻100} facets, which serve as growth surfaces for InGaN-based light-emitting diode quantum well active regions. Compared to growth on the polar {0001} plane, the piezoelectric fields in the multiple quantum wells (MQWs) can ...

In this paper, we provide a complete analytical description of the alignment kinetics of magnetic nanorods in magnetic field. Nickel nanorods were formed by template electrochemical deposition in alumina membranes from a dispersion in a water–glycerol mixture. To ensure uniformity of the dispersion, the surface of the nickel nanorods was covered with polyvinylpyrrolidone (PVP). A 40–70 nm coati...

Nanoscaled WO3 particles coated on ZnO nanorod composites were fabricated through combining hydrothermal technique with chemical precipitation process. The configuration, crystal structure and element composition of the as-prepared WO3/ZnO nanorods were characterized by field-emission scanning electron microscopy (FESEM), transmission electron microscope (TEM) along with a high resolution trans...

Vancomycin functionalized silver nanorod arrays substrates were used to obtain the surface enhanced Raman scattering (SERS) signals of six foodborne pathogenic bacteria in mung bean sprouts samples using both a portable and a handheld Raman system. The silver nanorod arrays substrates were optimized to facilitate quantitative, rapid, and sensitive detection of Salmonella enterica serotype Anatu...

Well-defined CdS nanograin-sensitized one-dimensional (1D) Zr:α-Fe2O3 nanostructured arrays with enhanced photoelectrochemical performance are synthesized directly on F-doped SnO2 (FTO) using the hydrothermal method. Owing predominantly to the appropriate photogenerated electron-hole separation and charge collection in 1D Zr:α-Fe2O3 nanorods, hydrothermally deposited CdS/1D Zr:α-Fe2O3 samples e...

It is well known that the optical properties of spherical metal particles can be described with Rayleigh approximation or rigorous Mie theory. But for single metallic nanorods, a theory capturing fundamental resonance and scattering features still absent. In this study, an analytical model developed nanorod, considering longitudinally non-uniform conduction current surface charges. With circuit...
