Chemoresponsive and Bioresponsive Polymers

There are numerous examples of polymer surfaces that react with a change of their properties when brought into contact with certain species. These trigger species can be low molar mass molecules (chemoresponsive) or complex biomolecules like DNA or proteins (bioresponsive). Both types of responsive surfaces exist in several varieties depending on their mode of action and the parameter that they affect. 

One way of obtaining chemically responsive polymer surfaces relies on the concept of structural color. In this case, the color of an object is not generated by selective absorption of light, but by interference and Bragg reflection induced by
