cell-based biosensors have become a research hotspot in biosensors and bioelectronics fields. the main feature of cell-based biosensors is the immobilization of living cell on the surface of transducers. different types of polymers which are used as scaffolds for cell growth should be biocompatible and have reactive functional groups for further attachment of biomolecules. in this work, the cel...

in order to examine the effects of silver, zinc, nickel, zinc- copper nanoparticles on germination, seedling establishment, and enzyme activity of alfalfa seeds, a factorial experimental was conducted in a randomized complete design with three replications in the seed laboratory, college of agriculture and natural resources, university of tehran in karaj. the objective of this study was to dete...

Nanotechnology represents a new and enabling platform that promises to provide a range of innovative technologies for biological applications. ZnO nanoparticles of controlled size were synthesized, and their cytotoxicity toward different human immune cells evaluated. A differential cytotoxic response between human immune cell subsets was observed, with lymphocytes being the most resistant and m...

We prepared two types of cholesterol hydrophobically modified pullulan nanoparticles (CHP) and carboxyethyl hydrophobically modified pullulan nanoparticles (CHCP) substituted with various degrees of cholesterol, including 3.11, 6.03, 6.91 and 3.46 per polymer, and named CHP-3.11, CHP-6.03, CHP-6.91 and CHCP-3.46. Dynamic laser light scattering (DLS) showed that the pullulan nanoparticles were 8...

Faraday Discussions are unique international meetings that focus on miscellaneous areas of chemistry and have been held for over 100 years. The format of these meetings is distinctive because delegates submit their papers in advance and these are distributed to all the participants prior to the meeting. During the meeting, the presenting authors are given fi ve minutes to summarise the key poin...

The interaction of a nanoparticle with light is affected by nanoparticle geometry and composition, as well as by focused beam parameters, such as the polarization and numerical aperture of the beam. The interaction of a radially focused beam with a prolate spheroidal nanoparticle is particularly important because it has the potential to produce strong near-field electromagnetic radiation. Stron...

The endothelial phenotype of tumor blood vessels differs from the liver and forms an important base for endothelium-specific targeting by antibody-coated nanoparticles. Although differences of shear stress and ligand avidity can modulate the nanoparticle binding to endothelium, these mechanisms are still poorly studied. This study analyzed the binding of antibody-coated nanoparticles to tumor a...

Abstract—This paper deals with the theoretical and numerical investigation of magneto hydrodynamic boundary layer flow of a nanofluid past a wedge shaped wick in heat pipe used for the cooling of electronic components and different type of machines. To incorporate the effect of nanoparticle diameter, concentration of nanoparticles in the pure fluid, nanothermal layer formed around the nanoparti...

BACKGROUND We study the human serum albumin (HSA) protein-CuO nanoparticle interaction to identify the specific binding site of protein with CuO nanoparticles by molecular docking and compared it with HSA-TiO2 nanoparticle interaction. METHODS The protein structural data that was obtained using Autodock 4.2. RESULTS In case of CuO np-HSA interaction, the distances from the centre of Subdoma...
