The present contribution reports a novel electrode based on an ITO substrate surface-modified with nanofilm of nickel tetrasulfonated phthalocyanine (NiTsPc) cerium oxide nanoparticles (CeO2) for the effective differential pulse voltammetric detection acetaminophen, which is contaminant emerging concern (CEC). optimized ITO/NiTsPc/CeO2 responds linearly (r2 > 0.99) to acetaminophen in range ...

In this paper, a label-free aptamer based detection system (apta-DS) was investigated for detecting colon cancer cells. For this purpose, we employed an aptamer specific to colon cancer cells like HCT116 expressing carcinoembryonic antigen (CEA) on their surfaces. Capture aptamers were covalently immobilized on the surface of gold nanoparticles (GNPs) through self-assembly monolayer of 11-merca...

Indium tin oxide (ITO) is an important electrode material in electrochemical studies. However, it presents some chemical and limitations, which are often underestimated. In this work the behavior of ITO investigated under opto-electrochemical monitoring a scanning cell microscopy, SECCM, configuration during hydrogen evolution reaction (HER) 5 mM H2SO4, concentration for remains stable. The sit...

In this report, poly(1,8-diaminonaphthalene) as a molecularly imprinted polymer (MIP) coated on gold nanoparticles (nano Au) dispersed ITO electrode was prepared. While nano Au strongly enhance the Raman signal of analyte, MIP layer allows to selective trap and enrich analyte molecules close surface. fact, by building matrix around target molecules, in case is rhodamine B then extraction we can...

In this paper, we describe a method for the growth of gold nanowires and nanoplates starting from a bilayer array of gold seeds, anchored on electrically conducting indium tin oxide (ITO) substrates. This is based on a seed-mediated growth approach, where the nanoparticles attached on the substrate through molecular linkages are converted to nanowires and nanoplates at certain cetyltrimethylamm...

The first experimental results on the functioning of liquid crystal cells doped with CoFe2O4 nanoparticles are presented. Transmission spectra in visible and near-infrared range, dynamic parameters Fredericks effect, refractive characteristics, as well wetting angles mesophase sensitized surfaces have been obtained. measured were K8 Crown glass, conductive ITO treated a surface electromagnetic ...

A modified aqueous sol-gel route was developed using ultrasonic power for the silica coating of indium tin oxide (ITO) nanoparticles. In this approach, organosilane with an amino functional group was first used to cover the surface of as-received nanoparticles. Subsequent silica coating was initiated and sustained under power ultrasound irradiation in an aqueous mixture of surface-treated parti...
