| 中文摘要 | a new type of eco-friendly molecularly imprinted polymer (mip) was synthesized through an efficient one-pot room-temperature sol-gel polymerization and applied as a molecular recognition element to construct dopamine (da) fluorescence (fl) optosensor. highly luminescent carbon dots (cds) were firstly synthesized via a one-step reaction in organosilane, and their surface were anchored with mip matrix (cds@mip). the resulting composite of a synergetic combination of cds with mip showed high photostability and template selectivity. moreover, the composite allowed a highly sensitive determination of da via fl intensity decreasing when removal of the original templates. the new mip-based da sensing protocol was applied to detect da concentration in aqueous solution, the relative fl intensity of cds@mip decreased linearly with the increasing da in the concentration range of 25-500 nm with a detection limit (3 sigma) of 1.7 nm. furthermore, the proposed method was successfully intended for the determination of trace da in human urine samples without the interference of other molecules and ions.
