Claim 0:
1. A graphene oxide composition comprising water soluble carbon nanoparticles, each carbon nanoparticle including a plurality of carboxylic groups and hydroxyl groups such that the carboxylic groups comprise at least about 20% of the total weight of the carbon nanoparticle,
wherein the carbon nanoparticle is reversibly convertible between a first open form having a size of about 40 nm to about 200 nm and a second closed form having a diameter of about 40 nm to about 120 nm, wherein the open form can be converted to the closed form at a pH of about 6.8 or lower and the closed form can be converted to the open form at a pH of about 7.2 or higher.
