AbstractChemical sensors utilizing immobilized enzymes and proteins are important for monitoring chemical processes and biological systems. Glucose oxidase (GOx) from Aspergillum Niger is a flavoenzyme that has been used to determine glucose. Among the conventional methods of enzyme deposition the main strategy consists in its entrapment in an inert matrix adsorbed on the electrode surface. We report here the synthesis and physical – chemical characterization of a new bionanocomposites obtaine...

Abstract Molecular imprinting is a versatile and ecological method for obtaining polymeric materials with a lot of applications in the field of pharmacy, medicine and biosensor assays. In this work, a new method of alternative molecular imprinting to design imprinted poly (vinyl alcohol) films has been proposed. Glycyrrhizinic acid has been used as template molecule. To demonstrate the obtaining of the molecular imprinted poly (vinyl alcohol) and its selectivity, studies of glycyrrhizinic and...

The metal sensitivity and selectivity of two fluorescent proteins was investigated. The studied proteins are mutant forms of the red fluorescent protein (DsRed); according to our results, both proteins showed sensitivity to the presence of copper[II] and nickel ions. The fluorescence intensity of the proteins has decreased significantly in the presence of copper ions in the micromolar range. Metal binding by these proteins is a reversible process, as addition of a chelating agent liberates the b...

The enzyme-based biosensor stability and its analytical performance depend on both the immobilization process and the matrix used for immobilization of the enzyme into a stable layer. In this paper, the development and evaluation of an optimal enzymatic layer for stable encapsulation of the acetylcholinesterase enzyme (AChE) through the sol-gel method onto mediated carbon-ink screen-printed electrodes was performed, obtaining electrochemical enzyme-based biosensors. The enzyme was immobilized on...
