Electrochemical enzyme biosensors are extensively utilized in clinical analysis and environmental monitoring, yet achieving effective immobilization while maintaining high activity remains a challenge. In this work, we developed flow-through biosensor system using 3D-printed electrochemical cell fabricated from commercially available poly (lactic acid). After modification with thiacalixarene-functionalized oligo acids) (OLAs), the material enabled efficient of uricase on inner surface...
Voltammetric DNA sensor has been proposed on the platform of glassy carbon electrode covered with black adsorbed pillar[5]arene molecules. Electropolymerization Neutral Red performed in presence native or oxidatively damaged resulted formation hybrid material which activity depended conditions. The assembling surface layer was confirmed by scanning electron microscopy and electrochemical impedance spectroscopy. influence redox polymeric dye investigated a significant increase peak currents...
Electrochemical flow-through sensor based on pillar[3]arene[2]quinone (P[3]A[2]Q) derivative was developed. Nitrophenol determination P[3]A[2]Q redox current changes. Also, the shift of cathodic potential observed compared to nitrophenol reduction registration directly. Using carbon black (CB) as a matrix for macrocycle implementation provided stability in flow when it applied with 3D printed cell. CB and were drop casted from same aliquot providing one-step modifying layer production by...
Abstract We proposed a voltammetric DNA sensor based on glassy carbon modified with black, pillar[5]arene, and electropolymerized Neutral Red. To increase signal sensitivity, Methylene Blue in monomeric polymeric forms was introduced into the surface layer of as specific intercalator electron transfer mediator. The electrochemical characteristics coating are determined, depending composition preparation method; consistent change peak currents dyes is observed during incubation solution...
The approaches to the synthesis of newly obtained pillar[3]arene[2]hydroquinone and its derivative with functional ammonium substituents (P[3]A[2]HQae) are suggested. structures macrocycles synthesized were confirmed characterized by a complex physical methods. P[3]A[2]HQae has found application as an electron transfer mediator for determination dopamine ascorbic acid voltammetric sensor developed. For successful assembly glassy carbon electrode (GCE) was modified black (CB),...
