A nano-sized hydrogel is made of a water-soluble chain containing carboxylic acid moieties and polyethylene side chains. Such a nanogel is applicable as a cancer-drug delivery agent or an imagining agent, where either a cancer drug, such as cisplatin, or an imaging agent, such as Gd3+. The complexation of the cancer drug or the imaging agent with the carboxyl moieties leads to the hydrogel formation.
