Claim 16:
17. A method for delivering a molecule encapsulated in a water-soluble carbon nanoparticle, the method comprising:
providing a water-soluble carbon nanoparticle, having 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, the carbon nanoparticle having a first open form having a size of about 40 nm to 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;
encapsulating the molecule in the carbon nanoparticle at a pH of 6.8 or lower;
delivering the carbon nanoparticle and encapsulated molecule; and
releasing the encapsulated molecule from the carbon nanoparticle at a pH of 7.4 after delivery.
