In this chapter we explore molecularly imprinted polymers (MIPs) as both selective recognition elements and responsive materials in a wide variety of fields, focussing on drug delivery systems, sensor development and separation/purification purposes. The effects of physical and chemical stimuli on the polymer conformation are thoroughly discussed. A brief overview of the current state of the art, current trends and a list of the main challenges those materials face is also presented. The impact of different pre- and post-synthetic modifications, the polymerisation conditions and the final shape and morphology on their final performance is taken into consideration. Special attention is paid to the fabrication of MIP-based composites to develop multi-responsive materials. Finally, some current and paradigmatic examples are selected to illustrate the response and recognition mechanisms of such polymers towards a wide variety of stimuli and target molecules of social significance.
