Molecularly imprinted polymer decorated nanoporous gold for highly selective and sensitive electrochemical sensors
Electrochemical nanosensors based on nanoporous gold leaf (NPGL) and molecularly imprinted polymer (MIP) are developed for pharmaceutical analysis by using metronidazole (MNZ) as a model analyte. NPGL, serving as the loading platform for MIP immobilization, possesses large accessible surface area with superb electric conductivity, while electrochemically synthesized MIP thin layer affords selec...
متن کاملFabrication of a Selective and Sensitive Electrochemical Sensor Modified with Magnetic Molecularly Imprinted Polymer for Amoxicillin
A modified electrochemical sensor for the determination of amoxicillin (AMX) was reported in this paper. The magnetic molecularly imprinted polymer (MMIP) were suspended in AMX solution and then collected on the surface of a magnetic carbon paste electrode (CPE) via a permanent magnet, situated within the carbon paste electrode and then the voltammetry signals were recorded. It was confirmed th...
متن کاملA nanoporous gold membrane for sensing applications.
Design and fabrication of three-dimensionally structured, gold membranes containing hexagonally close-packed microcavities with nanopores in the base, are described. Our aim is to create a nanoporous structure with localized enhancement of the fluorescence or Raman scattering at, and in the nanopore when excited with light of approximately 600 nm, with a view to provide sensitive detection of b...
متن کاملA Microfluidic Device for Opto-Electrochemical Sensing
A microfluidic device that contains a silica film as optical transducer and electrochemical electrode was used to monitor how ferricyanide ion behaves within nanoporous matrix. This prototype device allows UV-VIS absorption spectroscopy and cyclic voltammetry to be performed at the same time. Significant reducing in leaching of redox molecules proved this device integrated with silica film can ...
متن کاملCO2-Selective Nanoporous Metal-Organic Framework Microcantilevers
Nanoporous anodic aluminum oxide (AAO) microcantilevers are fabricated and MIL-53 (Al) metal-organic framework (MOF) layers are directly synthesized on each cantilever surface by using the aluminum oxide as the metal ion source. Exposure of the MIL53-AAO cantilevers to various concentrations of CO2, N2, CO, and Ar induces changes in their deflections and resonance frequencies. The results of th...
