| 摘要 |
A surface modified nanoparticle includes a nanoparticle and a phenol compound used for modifying the nanoparticle. The phenol compound has a formula of (a) or (b), wherein n=1˜9, X is selected from the group consisted of NH2, OH, PH4, COOH and SH, R1 is selected from the group consisted of C1-C5 alkyl group, aryl group, alkenyl group, alkynyl group, alkylamino group and alkoxy group. Each carbon atom of the phenol group may be independently substituted or non-substituted. The substituent of the carbon atom of the phenol may be selected from the group consisted of halogen, C1-C5 alkyl group, cyano (CN), trifluoromethyl (CF3), alkylamino group, amino and alkoxy group. The present invention may be used for anti-oxidant and/or decreasing the toxicity of the nanoparticle. A preparation method of surface modified nanoparticle is also herein provided. |
