A bio-nano-engineered platform fabricated from cerium oxide-carbon nanoparticles stabilized with chitosan for label-free sensing of a lung cancer biomarker.

Herein, we report a label-free cancer biosensor designed for carcinoembryonic antigen (CEA) detection using a nanohybrid comprising CeO nanoparticles, carbon nanoparticles (CNPs), and chitosan (Ch). CeO nanoparticles were prepared using a simple green synthesis process. A thin film of the CeO-CNPs-Ch nanohybrid was formed on indium tin oxide (ITO)-coated glass plates that endowed a high surface area, excellent stability, and good adsorption for the efficient loading of CEA antibodies.

Effect of Zn Doping on Structural/Microstructural, Surface Topography, and Dielectric Properties of BiFeO Polycrystalline Nanomaterials.

In the present research work, bismuth ferrite mullite type BiFeZnO (0.0 ≤ ≤ 0.05) nanostructures are prepared by a chemical coprecipitation method and the effect of Zn doping concentration on the structural, surface topography, and dielectric properties is reported.

Dielectric study of Clove oil.

Dielectric properties of clove oil were determined using an impedance gain phase analyzer (HP 4194 A) at discrete frequencies between 10 kHz and 3 MHz and a range of temperature between 25 °C and 45 °C. A micro processor controller based temperature controller (Julabo F-25) was used for keeping the temperature of clove oil constant. Dielectric constant of the sample is found to decrease with increase in frequency and temperature, while dielectric loss decreases with increase in frequency but increases with increase in temperature.
