Abstract: A molecularly imprinted polymer sensor device for detecting the presence of a taggant molecular structure in a fluid is disclosed. The molecularly imprinted polymer sensor device comprises a molecularly imprinted crosslinked polymer having a crosslinked core and a plurality of polymer arms attached to the core, wherein the core has molecular sized cavities adapted to selectively receive and bind displacement molecules having the taggant molecular structure and a colorimetric indicator, said displacement molecule being selectively removed from the molecularly imprinted crosslinked polymer and replaced with the taggant molecular structure upon exposure to the fluid containing the taggant molecular structure therein, thereby indicating the presence of the taggant molecular structure in the fluid.
