The detection of molecules at an ultralow level by Surface-Enhanced Raman Spectroscopy (SERS) has recently attracted enormous interest for various applications especially in biological, medical, and environmental fields. Despite the significant progress, SERS systems are still facing challenges for practical applications related to their sensitivity, reliability, and selectivity. To overcome th...

Efficient solar driven photoelectrochemical (PEC) response by enhancing charge separation has attracted great interest in the hydrogen generation application. The formation of one-dimensional ZnO nanorod structure without bundling is essential for high efficiency in PEC response. In this present research work, ZnO nanorod with an average 500 nm in length and average diameter of about 75 nm was ...

Heteronanostructured zinc oxide nanorod (ZnO NR) array are vertically grown on polydimethylsiloxane (PDMS) through a hydrothermal method followed by an in situ deposition of silver nanoparticles (Ag NPs) through a photoreduction process. The Ag-ZnO heterostructured nanorods on PDMS are measured with an average diameter of 160 nm and an average length of 2 μm. ZnO NRs measured by high-resolution...

A multilayer TiO(2) nanorod-assembled cloth/nanorod array based electrode was fabricated by transferring different layers of TiO(2) nanorod-assembled cloth (TNRC) onto nanorod array grown on the conducting FTO substrate (titania nanorod, TNR). Combining the superior electron transport characteristics of TNR and outstanding optical properties of TNRC, the nanostructured electrode composed of two...

A multicomponent nanostructure comprising of gold nanorod-nanoparticle (AuNR-AuNP) composites was fabricated to detect thrombin at subnanomolar concentrations in diluted human blood serum. Simulation and experiments revealed that the strong electromagnetic coupling resonance at the nanorod-nanoparticle junction of these probes can be used to construct highly sensitive SERS aptasensors.

(001)-oriented monoclinic nanorod and microplate WO3 films are fabricated on commercial FTO-coated glass substrates by a rubbing seed layer and a spin-coating seed layer assisted by hydrothermal reactions. The nanorod film obtained by the rubbing seed layer assisted by hydrothermal reactions is more regular and perpendicular to the substrate.

Dental enamel is the outermost layer of teeth and the hardest mineralized tissue in the human body. It consists of nanorod-like hydroxyapatite (HA) crystals arranged into a highly organized micro-architectural unit called an enamel prism. These special units play an important role in determining the unique physicochemical properties of dental enamel. Cells (ameloblasts) and enamel proteins are ...

Superparamagnetic Fe₃O₄ nanoparticles on hydroxyapatite nanorod based nanostructures (Fe₃O₄/HAp) were synthesized using hydrothermal techniques at 180 °C for 12 h and were used as drug delivery nanocarriers for cancer cell therapeutic applications. The synthesized Fe₃O₄/HAp nanocomposites were characterized by X-ray diffraction analysis (XRD), Field emission scanning electron microscopy (FESEM)...

Static bone scan was performed in 46 patients for evaluation of ocular Hydroxyapatite Vascularization. Study Findings indicated that bone scan, with TC-99m MDP is an appropriate method for evaluation of Hydroxyapatite Vascularization and for estimating the time For peg insertion into the Hydroxyapatite implant. Our study showed proper Hydroxyapatite Vascularization when the ratio of activ...
