Abstract
Systems and methods for the detection of one or more target molecules, such as benzene, are described. The systems and methods may include a molecularly imprinted polymer film; a sensing material, wherein the molecularly imprinted polymer film comprises a polymer host with one or more binding sites for one or more target molecules. The molecularly imprinted polymer film may be coated upon the sensing material.
Claims14
A system for the detection of benzene, the system comprising:
- a polymer film molecularly imprinted with a template molecule to form cavities complementary in shape to benzene, each of the cavities forming a binding site specific for benzene;
- a sensing material for detecting binding of benzene to the polymer film, the polymer film being coated upon the sensing material, wherein the template molecule is benzene.
A method for producing a molecularly imprinted polymer film for detection of benzene, comprising:
- dissolving a polymer, including a structural component and a reporting component, in a first solvent to form a first solution;
- mixing a template molecule into the first solution to form a second solution, the template molecule being benzene;
- coating the second solution onto a sensing material to form a first polymer film;
- and
- removing the template molecule from the first polymer film to form a molecularly imprinted polymer film.
