Holographic Molecularly Imprinted Polymers for Label-Free Chemical Sensing (Adv. Mater. 4/2013)

A new material combining a molecularly imprinted polymer for specific analyte recognition, and a holographic structure for optochemical sensing is described by Karsten Haupt, Olivier Soppera, and co-workers on page 566. The material is obtained in one step through photo-polymerization with interfering laser beams, resulting in a holographic molecularly imprinted polymer film that is hierarchically structured at four length scales. Specific binding of the target analyte testosterone is measured by diffraction analysis.
