Microgel adsorption onto solid/liquid or liquid/liquid interfaces is discussed. We address the modification of electrodes by microgels. Chargeable poly(N-isopropyl acrylamide)-based (PNIPAM) microgels can have rather different adsorption properties toward graphite or noble metal surfaces. In addition to the well-known electrostatic adsorption of microgels to oppositely charged surfaces, we propose here and adsorption of PNIPAM-based microgels to graphite driven by hydrophobic interactions. Hence, a stimulated adsorption can be used to deposit enzymes for biosensoric applications. We also demonstrate that electrochemical impedance spectroscopy can be suitable tool to detect adsorption. Further, we address polymers adsorbed to liquid/liquid interfaces. Here, the structure and properties of microgels at interfaces will be highlighted. We focus on different techniques, like Langmuir trough experiments and microscopic mathods. Finally, we demonstrate how an interface can promote the complexation between weakly interacting polymers.
