    • Chemical and biosensors are disclosed. An optical waveguide is used to conduct electromagnetic radiation by total internal reflection in parallel through a reference waveguide portion and at least one analyte waveguide portion. The electromagnetic radiation is then converged into an exit beam. The external surface of at least the analyte portion is covalently modified, or functionalized, relative to the reference portion. Resulting interaction of the functionalized surface with molecules comprising an analyte causes a phase change in the electromagnetic radiation passing through the analyte portion relative to the reference portion sufficient to generate a corresponding and measurable interference pattern in the exit beam. A waveguide surface is functionalized by exposure to a reagent, having molecules each comprising a nitrenogenic group and a functionalizing group, in the presence of energized charged particles such as electrons and ions, photons, or heat, which transform the nitrenogenic reagent to a nitrene intermediate. The resulting reaction causes the functionalizing groups to covalently bond to the surface. The functionalizing groups can then participate in downstream chemistry whereby any of a large variety of functional groups, including biological molecules, can be covalently bonded to the surface. Thus, the waveguide surface can be made selectively responsive to a wide variety of analytes, including cells and other biological structures.

    • A molecularly imprinted substrate and sensors employing the imprinted substrate for detecting the presence or absence of analytes are described. One embodiment of the invention comprises first forming a solution comprising a solvent and (a) a polymeric material capable of undergoing an addition reaction with a nitrene, (b) a crosslinking agent (c) a functionalizing monomer and (d) an imprinting molecule. A silicon wafer is spincoated with the solution. The solvent is evaporated to form a film on the silicon wafer. The film is exposed to an energy source to crosslink the substrate, and the imprinting molecule is then extracted from the film. The invention can be used to detect an analyte by forming films which are then exposed to a reaction energy to form a crosslinked substrate. The imprinting molecules are extracted from the crosslinked substrate. The film is exposed to one or more of the imprinting molecules for a period of time sufficient to couple the imprinting molecules to the film. The presence of the molecules is then detected. The invention also provides a molecularly imprinted polymeric material and sensors employing the molecularly imprinted polymeric material.

    • Methods for covalently modifying surfaces of various substrates are disclosed, along with various substrates having surfaces modified by such methods. Candidate surfaces include various polymeric, siliceous, metallic, allotrophic forms of carbon, and semiconductor surfaces. The surfaces are exposed to a reagent, having molecules each comprising a nitrenogenic group and a functionalizing group, in the presence of energized charged particles such as electrons and ions, photons, or heat, which transform the nitrenogenic reagent to a nitrene intermediate. The nitrene covalently reacts with any of various chemical groups present on the substrate surface, thereby effecting nitrene addition of the functionalizing groups to the substrate surface. The functionalizing groups can then participate in downstream chemistry whereby any of a large variety of functional groups, including biological molecules, can be covalently bonded to the surface, thereby dramatically altering the chemical behavior of the surface. Such functionalizations of the surface can be done in a single reactive step or in multiple reactive steps.
