Thin films of conducting molecularly imprinted polymers (MIPs) were prepared for simultaneous chronoamperometry (CA) and piezoelectric microgravimetry (PM) determination several explosive nitroaromatic compounds (NTs) including 2,4,6-trinitrophenol (TNP), 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitrobenzene (TNB), 2,4-dinitrotoluene (DNT). For that, the bis(2,2'-bithienyl)-(4-aminophenyl)methane 1 functional monomer allowing π-π stacking recognition NTs was designed synthesized. Both...
A molecularly imprinted polymer (MIP) film based electrochemical sensor for selective determination of tyramine was devised, fabricated, and tested. Tyramine is generated in smoked fermented food products. Therefore, it may serve as a marker the rottenness these Importantly, intake large amounts by patients treated with monoamine oxidase (MAO) inhibitors lead to "cheese effect", namely, dangerous hypertensive crisis. The limit detection at S/N = 3 chemosensor, both differential pulse...
Preparation and electrochemical behavior of new hybrid materials composed multi-walled carbon nanotubes (CNTs) that were derivatized with poly(diallyldimethylammonium) chloride modified vanadium-mixed addenda Dawson-type heteropolytungstate, [P2W17VO62]8−, is described here. These nanostructured composite systems exhibited fast dynamics charge propagation. They characterized by the transport (effectively diffusional) kinetic parameter approximately 8 × 10−8 cm−2 s−1/2 specific capacitance 82...
A new strategy of simple, inexpensive, rapid, and label-free single-nucleotide-polymorphism (SNP) detection using robust chemosensors with piezomicrogravimetric, surface plasmon resonance, or capacitive impedimetry (CI) signal transduction is reported. Using these chemosensors, selective a genetically relevant oligonucleotide under FIA conditions within 2 min accomplished. An invulnerable-to-nonspecific interaction molecularly imprinted polymer (MIP) electrochemically synthesized probes...
A chemosensor with a molecularly imprinted polymer (MIP) film as the recognition unit selective to carnosine biomarker was engineered, devised and fabricated. The molecular structure of pre-polymerization complex template carboxy 18-crown-6 ether derivatives bis(2,2'-bithien-5-yl)methane functional monomers thermodynamically optimized by density theory (DFT) at B3LYP/6-31g(d) level. calculated high negative Gibbs free energy change, ΔG = -227.4 kJ mol-1, indicated formation very stable...
A new conducting polymer of biotinylated bis(2,2'-bithien-5-yl)methane was prepared and applied as the recognition unit two different biosensors for selective oligonucleotide determination using either electrochemical impedance spectroscopy (EIS) or piezoelectric microgravimetry (PM) label-free analytical signal transduction. For preparation this unit, first, a functional monomer designed synthesized. Then, potentiodynamically polymerized to form films on surface glassy carbon electrode...
