There is enormous potential for the analytical applications of molecularly imprinted polymers (MlPs); for example, the imprinted polymer sites can function as the molecular recognition element of sensors, immunoassays, and separation media, However, difficulties with formulation variables and the need for empirical optimization have inhibited the widespread use of MlPs by the general scientific community, While Investigating new crosslinkers for molecular imprinting, we have recently discovered a much simpler approach to MIP formation which utilizes a single crosslinking monomer, NOBE (N,Obismethacryloyl ethanolamine) in addition to template, solvent and initiator (shown in Scheme 1). We have given this molecular imprinting method the acronym "OMNiMIPs" which stands for one monomer molecularly imprinted polymers.1 This new formulation eliminates variables such as choice of functional monomer (FM) and crosslinker (XL), the ratio of functional monomer to crosslinker (FWXL), and the ratio of functional monomer to template which normally complicates MIP design. The affects of OMNiMIP performance variables toward molecular recognition indicate significant differences between these new materials and traditional MlPs formulated with ethyleneglycol dimethacrylate (EGDMA) and methacrylic acid (MAA). These differences and the utility of OMNiMIPs will be discussed. © 2007 Materials Research Society.
