Additionally, GO was chosen as the second ...Particularly, graphene oxide (GO), graphene's water-soluble derivative, has been found important potential applications in drug delivery [26-28] and enzyme immobilization due to their large specific surface area and abundant functional groups (epoxide, hydroxyl, and carboxylic groups).For carboxymethyl cellulose/reduced graphene oxide film preparation, sodium borohydride was used as a chemical reducing agent. The carboxymethyl cellulose films were prepared by using a solvent casting method, followed by an acid treatment to decrease the water solubility (98%) while enhancing the tensile strength (15%) and elastic modulus (32% ...We prepared graphene oxide by oxidizing graphite using a modified Hummer's method. 3, 11 The resulting GO (single layered and few-layered, Supp Info. Fig.S1) was soluble in water but aggregated in solutions rich in salts or proteins such as cell medium and serum ( Fig. 1a ).Apr 08, 2020 · View 2 Images. 1 / 2.
