Claim 0:
1. An apparatus for detecting one or more target molecules comprising:
a hydrophobic substrate; and
a sensor comprising:
two or more electrodes disposed on the hydrophobic substrate and separated from one another by a gap;
a plurality of nanostructures formed on or within an upper surface of each electrode,
a plurality of binding molecules attached to the plurality of nanostructures, wherein the plurality of binding molecules are configured to bind with the one or more target molecules;
a multiplexor coupled to the two or more electrodes configured to selectively switch the two or more electrodes between inducing an alternating current electrothermal (ACET) flow and detecting the one or more target molecules; and
an alternating current power source and impedance analyzer coupled to the multiplexor;
wherein the upper surface of each electrode and the plurality of nanostructures are hydrophilic.
