| 英文摘要 | this work presented a novel strategy for the synthesis of the hybrid structure silica/cdte/molecularly imprinted polymer (si-np/cdte/mip) to recognize and detect the template bovine hemoglobin (bhb). first, amino-functionalized silica nanoparticles (si-np) and carboxyl-terminated cdte quantum dots (qds) were assembled into composite nanoparticles (si-np/cdte) using the edc (1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride) chemistry. next, si-np/cdte/mip was synthesized by anchoring molecularly imprinted polymer (mip) layer on the surface of si-np/cdte through the sol-gel technique and surface imprinting technique. the hybrid structure possessed the selectivity of molecular imprinting technique and the sensitivity of cdte qds as well as well-defined morphology. the binding experiment and fluorescence method demonstrated its special recognition performance toward the template bhb. under the optimized conditions, the fluorescence intensity of the si-np/cdte/mip decreased linearly with the increase of bhb in the concentration range 0.02-2.1 mu m, and the detection limit was 9.4 nm. moreover, the reusability and reproducibility and the successful applications in practical samples indicated the synthesis of si-np/cdte/mip provided an alternative solution for special recognition and determination of protein from real samples. |
