Applicazioni

Immobilization of antibodies for use in ultrasensitive electrochemical immunosensors using the abundant amine groups and a large electroconductive surface area of reduced graphene oxide-tetraethylene pentamine (rGO-TEPA).
Amount of NH2 groups: In order to estimate the amount of NH2 groups in rGO-TEPA a reaction with tetrabromophthalic anhydride was performed and the Br amount was quantified by the Schöniger flask test. The value obtained corresponds to 1.1 mmol NH2/g.
