Sensors for the detection of analytes

The subject invention provides materials and methods of fabricating and using an electrochemical biosensor for continuous detection of biological analytes. In a specific embodiment, the biosensor detects a given analyte when the analyte binds with a molecularly imprinted polymer (MIP) matrix immobilized atop a sensing substrate eliminating the need for a redox probing agent commonly found in electrochemical biosensors. Furthermore, the detection sensitivity of the biosensor is enhanced by modifying the electrode surface with a plurality of nanoscopic metallic structures. Advantageously, technologies provided herein can be used in a variety of low-power electronics for wearable applications.

Molecularly imprinted carbon

Preparation of a molecularly imprinted carbon is described. The molecularly imprinted carbon has a surface that is imprinted on the molecular level for a specific template molecule of interest, making it highly selective for analytes corresponding to at least a portion of the template molecule. Devices including the molecularly imprinted carbon and their use in methods of detecting analytes are also described. As an example, dibutyl butylphosphonate (DBBP), a surrogate for chemical warfare agents, was used as a template molecule. Electrospun molecularly imprinted SU-8 and pyrolyzed polymer (PP) solid-phase microextraction (SPME) devices were prepared; their ability to preferentially extract DBBP from an aqueous matrix, with and without interferences present, was evaluated via comparison with non-imprinted SU-8 and PP SPME fibers. The electrospun devices demonstrated a higher selectivity for DBBP, as evidenced by their extraction time profiles. The MI-SPME fibers tested extracted at least 60% more DBBP than their non-imprinted counterparts.
