Controlled Evaporative Self-assembly of Molecularly Imprinted Polymers (MIPs) and PMMA blend solution for Highly Sensitive Detection of 2,4-D |
| 초록 |
Molecularly imprinted polymers (MIPs) have amassed the attention of researchers as a recognition element in chemo/biosensors, chromatography and bio-analysis due to specifically bind a chemical species. Herein, we report highly ordered MIPs and polymethyl methacrylate (PMMA) via controlled evaporative induced self-assembly for the detection of 2,4-dichlorophenoxyacetic acid (2,4-D) in an aqueous solution. When a droplet was loaded within a sphere-on-flat geometry, the evaporative induced pinning-depinning (i.e., "stick-slip") motion of solution at the droplet periphery lead to the spontaneous formation of well-organized concentric rings. This facile non-photolithographic approach of stick-slip guided surface patterning of MIP blend solution at room temperature and pressure provides a realistic alternative avenue towards constructing sensing devices for the determination of herbicides in a simple, robust, and cost-effective manner. |
