▎ 摘 要
NOVELTY - A fluorescence quenching method involves synthesizing iron oxide/gallium oxide composite material by hydrothermal synthesis. USE - Fluorescence quenching method for graphene oxide/graphene oxide quantitative analysis method used in biomedical applications such as preparation of magnetic fluorescent composite nano material and biomedical application. ADVANTAGE - The Fe3O4/GO composite material provides fluorescence quenching with fluorescence modified substance, which is sensitive and reliable. The method uses in situ analysis method, without the pre-processing of fussy time, convenient and efficient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a FeO/GO quantitative analysis method.
