We have demonstrated a fluorescent functional monomer instead of the traditional functional monomers for molecularly imprinted sensors. The sensors were firstly used to selectively detect 2,4,6-trichlorophenol (2,4,6-TCP) by solid fluorescence detection without a dispersion solution. Moreover, the selectivity and anti-interference ability of the SiO@dye-FMIPs sensor meet the requirements of a fluorescent sensor. The novel fluorescent monomer introduced into MIP is no longer just a fluorophore without recognizing ability. The fluorescence intensity of SiO@dye-FMIPs showed a linear response to 2,4,6-TCP concentration in the range of 0-100 nM with a detection limit of 0.0534 nM. We could also demonstrate that such a system can not only get rid of the confines of traditional functional monomers and detection manner, but also improved the applications of MIPs sensors in sensing systems.
我们已经展示了一种用于分子印迹传感器的荧光功能单体，而非传统功能单体。这些传感器首先被用于通过无分散溶液的固体荧光检测来选择性检测2,4,6-三氯苯酚（2,4,6-TCP）。此外，SiO@dye-FMIPs传感器的选择性和抗干扰能力满足荧光传感器的要求。引入到分子印迹聚合物（MIP）中的新型荧光单体不再仅仅是没有识别能力的荧光团。SiO@dye-FMIPs的荧光强度在0-100 nM范围内对2,4,6-TCP浓度呈线性响应，检测限为0.0534 nM。我们还可以证明，这样的系统不仅可以摆脱传统功能单体和检测方式的限制，还能改善分子印迹聚合物传感器在传感系统中的应用。
