US Patent 7998415 - Functionalized particles for composite sensors


This patent is from the Michigan Molecular Institute and includes some basic claims with priority going back to 2003 which may be very relevant to nanocomposite sensors. Claim 1 reads:

1. A chemical sensor comprising:

a transducer element; and

a layer of a composite material disposed on a surface of the transducer element, the composite material comprising a polymer matrix and a solid particulate filler dispersed in the polymer matrix, in which the particulate filler is comprised of functionalized particles having at least one sensory moiety capable of interactions with an analyte.
