Patent ID: 8535500

Claim:
A surface acoustic wave sensor device comprising: a surface acoustic wave sensor comprising a receptor, wherein the receptor binds to a target biomolecule of a sample; and an isolation component connected to the surface wave sensor, wherein the isolation component separates biomolecules having a size the same as or similar to the target biomolecule or separates biomolecules by excluding biomolecules having a size considerably different from the target biomolecule, through an electrophoresis process; and wherein the isolation component comprises a first chamber to contain a first buffer, and a first electrode positioned to contact the first buffer; a second chamber to contain a second buffer, and a second electrode positioned to contact the second buffer; a channel fluidly connecting the first and second chambers; a blocking wall at an end of the channel and between the channel and the first chamber or between the channel and the second chamber, wherein the blocking wall comprises a material that passes a current but does not pass ions and/or gases generated from the buffer; and a sample chamber at an entry of the channel and into which a sample is loaded.
