Description

Application

P-Benzoquinone along with tetrathiafulvalene (TTF) was used as mediators, in an experimental study based on different parameters affecting the preparation of enzyme electrochemical biosensors using self-assembled monolayer (SAM)-modified electrodes is reported. It may be used for spectrophotometric determination of cysteine and/or carbocysteine in a mixture of amino acids, shampoo, and pharmaceutical. It may also be used as an effective cogent in peroxide-initiated crosslinking of polypropylene.
