Abstract

During the last decades the development of sensors has been the subject of much attention due to an increased demand for sensor platforms and biosensors for environmental monitoring and clinician safety. Current efforts have focused on the search for sensors that are economically viable, highly sensitive and selective.Recently, smart polymer thin films activated by external stimuli have attracted considerable interest in the development of sensors for use in chemical and biochemical systems. These materials have a high sensitivity to physical or chemical changes occurring in the interface, and respond selectively to these changes to adapt to the environment. A material which meets these requirements is polymer brushes, which have been used in numerous applications such as protein binding and enzyme immobilization, chromatography supported, and functionalized membrane. Despite their interesting properties and numerous reports describing the potential of the polymer brush as sensitive surface, its use in real applications of sensing received little or no attention so far.
