The paper reports on the charge transport in sandwich-like graphene / Co nanoparticles structure (G/CoNPs/G). It is fabricated by combining electrochemical deposition of onto a single layer CVD and their capping with another layer. isolated semi-spherical, surface oxidized NPs 250 nm diameter serve as support for top provide its suspended state confirmed atomic force microscopy revealing period...

The biocompatible surface modification of metal oxide nanoparticles via surface functionalization technique has been used as an important tool in nanotechnology and medicine. In this report, we have prepared aqueous dispersible, trivalent metal ion (samarium)-doped cerium oxide nanoparticles (SmCNPs) as model redox altered CNPs of biological relevance. SmCNP surface modified with hydrophilic bi...

Abstract We investigated the interaction of As(III) with As(III)-binding DNA aptamers (Ars-3). The binding Ars-3 to was using an sequence and a few control sequences. As result, we conclude that cannot bind can adsorb onto gold nanoparticles selectivity. However, concentration could be determined by simple analysis method Ars-3, measured As(V) concentrations separately in As(III)/As(V) mixed sa...
