BACKGROUND The development of DNA biosensor has attracted considerable attention due to their potential applications, including gene analysis, clinical diagnostics, forensic study and more medical applications. Using electroactive daunomycin as an indicator, the hybridization detection was measured by differential pulse voltammetry in this study. RESULTS Electrochemical DNA biosensor was deve...

How graphene oxide (GO) with its step edges and wrinkles (∼1-2 nm) acts as a catalyst in hydrothermal nucleation and growth is demonstrated. TiO2 whiskers were prepared by using GO as a support, while TiO2 nanograss was prepared without using GO.

Carbon microelectrodes are being used extensively in numerous applications due to their intriguing and promising material properties. Here, we present the optimized fabrication of carbon nanograss (CNG) electrodes with a single-step UV lithography SU-8 photoresist followed by maskless reactive-ion etching pyrolysis. This simple method provides nanostructured high surface area suitable for elect...

A novel BDD nanograss array has been prepared simply on a heavily doped BDD film by reactive ion etching for use as an electrochemical sensor, which improved the reactive site, promoted the electrocatalytic activity, accelerated the electron transfer, and enhanced the selectivity.

Using high resolution focused ion beam scanning electron microscopy (FIB-SEM) we study the details of cell-nanostructure interactions using serial block face imaging. 3T3 Fibroblast cellular monolayers are cultured on flat glass as a control surface and on two types of nanostructured scaffold substrates made from silicon black (Nanograss) with low- and high nanowire density. After culturing for...

the water deficit is the most important limiting non-biological factor to achieve the potential yield of crops. to evaluate the effect of silicon application on yield of millet under drought stress in field an experimental was carried out. treatments were included three irrigation regimes after 60 (non-stress), 90 (moderate stress) and 120 (severe stress) mm evaporation from evaporation pan, cl...
