Abstract
Systems and methods for detection of biological agents are generally described.
Claims23
A device for sensing a chemical and/or biological analyte, comprising:
- a nanosensor, wherein at least a portion of the nanosensor is functionalized with a chemical and/or biological detector species;
- and
- a source of an alternating electric field, wherein the source is configured such that the electric field produced by the source is incident upon the nanosensor.
(canceled)
A method of sensing a chemical and/or biological analyte, comprising:
- applying an alternating electric field to a nanosensor functionalized with a chemical and/or biological detector species such that the Debye length of an analyte associated with the chemical and/or biological detector species is altered.
21-24. (canceled)
A method of sensing a chemical and/or biological analyte, comprising:
- applying an alternating electric field to a nanosensor functionalized with a chemical and/or biological detector species in the presence of a sample comprising an analyte;
- applying an electrical potential across the nanosensor;
- collecting a first set of data, based on the applied electrical potential, at points in time at which the alternating electric field is at a first power to provide a background signal;
- and
- collecting a second set of data, based on the applied electrical potential, at points in time at which the alternating electric field is at a second power that is different from the first power to provide a signal indicative of a property of the analyte, the detector species, and/or an interaction between the analyte and the detector species.
