Abstract: Abstract: The concept used to realize the modulation of molecular recognition in a molecularly imprinted polymer is presented. Creating a thermal phase transition within the binding framework, the imprinted material was prepared using Boc-phenylalanine as the template and pNIPAM as the sensitive unit. The results indicate that such a transition causes a clear modulation in the recognition behavior of the prepared polymer which depends on the operation temperature. At a relatively low temperature, the prepared polymer acts like a traditionally imprinted one, showing a highly specific recognition for the imprint species. However, the prepared polymer does not present any notable resolution at 40 ŚC. This recognition behavior is comparable to a process that can be switched on and off, thus making modulated recognition feasible
