TNT sensor containing molecularly imprinted sol gel-derived films
Publication date: 2007
The invention relates to a chemically-sensitive film for use in a detector for TNT, where the chemically sensitive film includes a porous, polymeric structure and a plurality of basic functional groups integral with the porous, polymeric structure, and the basic functional groups are selectively reactive with TNT. Waveguides coated with these films can be used in sensing devices that are capable of selectively detecting TNT in a sample. Methods of making the films, waveguides, and sensors are disclosed.
