Triblock Copolymer Synthesis of Highly Ordered Mesoporous Silica for Multifunctional Fluorescent Sensor in Chemical and Biological Probing |
| 초록 |
A versatile solid-state fluorescent sensor has been designed by functionalizing large-pore mesoporous silica templated by triblock copolymer with 3-isocyanatopropyltriethoxysilane and dansylcadaverine. The functionalized mesoporous silica material exhibited highly selective Hg2+ sensing due to the fluorophore moiety grafted on its surface. Much interestingly, the Hg2+-bound mesoporous material was able to be utilized in detecting various amino acids (especially highly sensitive to phenylalanine acid) in aqueous solution. More importantly, the dansylcadaverine-functionalized large-pore mesoporous material could be applied to fluorescent turn-on sensing of bovine serum albumin, demonstrating an all-round smart sensor in chemical and biological application. |
