We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Click here for more information.

Application

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.
