Surfacefunctionalization is the act of modifying the surface of a material by bringing physical,chemical or biological characteristics different from the ones originally found on the surface of a material.The modificationis ableto altering a wide range of characteristics of the surface,such as: hydrophilicity,surfacecharge,biocompatibility andchemicalreactivity.

In the first section,I will introduce our work on functionalization of mesoporous silica (MS) materials for drug loading and heavy metal adsorption.MS materials (with pore sizes of 2 to 50 nm) are well-known for their high specific surface areas which confers a high loading ability by simple physical adsorption.It is demonstrated that through surface modification,the drug loading capacity could be significantly improved and the drug release profile could be well controlled.Similarly,the removal capacity and selectivity for heavy metals on MS could be improved via suitable surface modification.

In the second section,the surface modification of graphene with polydopamine is reported.The polymer modification provides an ideal interface for in situ growth of other functional nanomaterials on graphene with various morphology and functionalities such as metal nanoparticles.The application of these graphene composites are given on areas such as electrocatalysis,biosensing,and Raman SERS.
