BACKGROUND
Enzymes are biocatalysts that play a vital role in the production of biomolecules. Plants can be a valuable and cost‐effective source for producing well‐structured recombinant enzymes. Glucose is one of the most important biological molecules, providing energy to most living systems. An electrochemical method for immobilization of enzyme is promising because it is economic, generates less...
A potentiometric sensor for studying charge based adsorption of proteins was created using a single‐piece polyaniline‐PVC ion‐selective electrode (ISE). Three different ISEs, two for Na+ and one for Cl− ion determination, were studied. The Na+‐ISEs consisted of a neutral calixarene‐based ionophore and one with a charged carrier dinonylnapthalenesulfonic acid (DNNSA) whereas for the Cl− ISE, an anion...
Electrochemical detection is a promising technique for bio-analytes sensing because of rapid analysis, good selectivity, reusability, thermal stability, linearity and relatively low cost. There have been consistent efforts to improve the performance of the electrochemical biosensors which include functionalization of the working electrode surface by polymer or nanomaterials. In this work, a cholesterol...
