Claim Text:
1. A sensor for detecting particulates in a sample, comprising: a first electrical contact for connecting to a variable voltage source; a second electrical contact for connecting to a current measuring device; and a plurality of nanotip sensors, each nanotip sensor in the plurality of nanotip sensors electrically connected to the first electrical contact and to the second electrical contact, and the each nanotip sensor comprising: a cathode, an anode, and a gap between the cathode and the anode, wherein the gap of at least one nanotip sensor is configured to be bridged by a one or more of a specific particulate to form an electrical circuit having a corresponding current versus voltage (I-V) characteristic, the specific particulate consisting of an antigen bound to an antibody, and the corresponding I-V characteristic identifying the antigen, and wherein the sensor for detecting particulates in a sample is operative to detect two or more different specific particulates.
