A novel bovine serum albumin(BSA) imprinted Mn-doped ZnS quantum dots(Mn:ZnS QDs) is firstly reported.The molecular imprinted polymer(MIP) functionalized Mn:ZnS QDs(Mn:ZnS@SiO_2@MIP) include the preparation of Mn:ZnS QDs,the coating of silica on the surface of Mn:ZnS QDs,and the functional polymerization by sol-gel reaction using 3-aminophenylboronic acid as the functional and cross-linking monomer in the presence of BSA(Mn:ZnS@SiO_2@MIP-BSA),and then the elution of the imprinted BSA on the surface of Mn:ZnS@SiO_2 QDs.The results showed that the phosphorescence of Mn:ZnS@SiO_2@MIP is stronger quenched by BSA than that of non-imprinted one(Mn:ZnS@SiO_2@NIP),indicating that the selectivity of the imprinted Mn:ZnS quantum dots toward BSA is superior to that of non-imprinted one.
