▎ 摘  要

NOVELTY - Preparing iron(II, III) oxide/graphene oxide (GO) composite nanomaterial comprises firstly preparing ferroferric oxide nano-microspheres by solvothermal reaction, then modifying the surface of iron(II, III) oxide nanospheres by using silicon dioxide and polyetherimide, using polyacrylic acid to modify the surface of graphene oxide, compositely preparing modified iron(II, III) oxide nanospheres and graphene oxide to obtain the finished product. USE - The nanomaterial is useful in preparing cancer cell capture kit, and preparing early screening and prognosis evaluation kit of clinical cancer (all claimed). ADVANTAGE - The method: has simple operation, short time-consuming, high sensitivity, strong broad spectrum and low material cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for iron(II, III) oxide/graphene oxide (GO) composite nanomaterial prepared by the above-mentioned method.
