Synthesis and characterization of Iron Oxide, rare earth Erbium Oxide, and Erbium Oxide blended Iron Oxide nanocomposites for biomedical activity application

In this report, we intend to synthesize iron oxide (Fe2O3), erbium oxide (Er2O3), and a composite of erbium oxide/iron oxide (Er2O3/Fe2O3) nanoparticles (NPs) by a microwave irradiation technique. After the synthesis, we explore the various physicochemical properties of the sample with the help of various systematic characterization techniques. First, the prepared sample has been subjected […]

Hydroxyapatite – starch nano biocomposites synthesis and characterization

Bone like hydroxyapatite (nHAp) was synthesized via an in situ biomimetic process in presence of wheat starch. The effect of polymer concentration alteration on the final structure of nHAp was investigated. Formation of the nHAp at room temperature was confirmed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Size and morphology of the […]

The effect of substrate temperature on fabrication of one-dimensional nanostructures of Tellurium

Tellurium nanostructures have been prepared by physical vapor deposition method in a tube furnace. The experiments were carried out under argon gas flow at a pressure of 1 mbar. Tellurium powder was evaporated by heating at 350°C and 430°C and was condensed on substrates at 110–250°C, in the downstream of argon gas flow. The products […]

Nanobiosensors and fluorescence based biosensors: An overview

A biosensor can sense biological elements after interaction with the recognition element. The signal produced due to interaction of the analyte with its biochemical element is transduced by a transducer and detected by appropriate modes. The miniaturization of these biosensors at the nano level using nanostructures as a platform for sensing the analyte or its […]
