A novel photo‐responsive drug carrier that doubles as a photothermal agent with a nanocookie‐like structure is constructed by coating amorphous carbon on a mesoporous silica support self‐assembled on a sheet of reduced graphene oxide. With a large payload (0.88 mmolg−1) of a hydrophobic anticancer drug, (S)‐(+)‐camptothecin (CPT), nanocookies simultaneously provide a burst‐like drug release and intense heat upon near‐infrared exposure. Being biocompatible yet with a high efficiency for cell uptake, nanocookies have successfully eradicated subcutaneous tumors in 14 days following a single 5 min NIR irradiation without distal damage. These results demonstrate that the nanocookie is an excellent new delivery platform for local, on‐demand, NIR‐responsive, combined chemotherapy/hyperthermia for tumor treatment and other biomedical applications.

“…In this method pristine or expended, intercalated or surface modified graphene is first swollen within the liquid monomer and after the diffusion of a suitable initiator, polymerization is initiated either by heat or radiation (Kuilla et al, 2010). A number of thermoplastic polymers/gaphene nanocomposites with much improved mechanical, thermal and electric properties were prepared by this method, e.g PMMA/graphene (enhanced storage moduli , glass transition temperatures and thermal stability (Kuilla et al, 2011)), PP/graphene (effective dispersion and high electic conductivity (Huang et al, 2010)), Nylon/graphene (increased Young's modulus (Xu & Gao 2010)) and PS/graphene (improved thermal properties (Patole et al, 2010)), etc. Solution intercalation, not so common, is based on the adsorption of polymer or pre-polymer onto graphene layers.…”

“…The attachment of PMMA composite microspheres to the graphite becomes possible and does not cause the selective anchoring of all PMMA composite microspheres. 19,20 The unanchored PMMA latex was removed by successive washing in methanol to get the PMMA/graphite composite microspheres. Finally, ULW proppants were obtained after being dried and sieved.…”

Ultra-lightweight heat resisting poly(methyl methacrylate) (PMMA)/graphite microspheres were successfully prepared via in situ suspension polymerization. The Fourier transform infrared and X-ray powder diffraction results confirmed the successful preparation of the composite microspheres. Field emission scanning electron microscope analysis illustrated that the graphite particles were dispersed in microspheres and the PMMA/graphite composite microspheres had good sphericity and roundness. Furthermore, density analysis indicated that the apparent density of composites microspheres was about 1.055-1.135g/cm 3 which was suitable for the transmission with water carrying. The results from thermodynamic test revealed that the thermal stability of the composite was significantly improved with increasing graphite content, which could be used as ultra-lightweight proppant in deep underground. In addition, the crushing rate decreased to 0.5% with graphite ratio of 3.0% at the pressure of 69 MPa. Therefore, PMMA/Graphite composite microspheres exhibit a promising application in petroleum or gas exploitation as water carrying fracturing proppants.
