Abstract
A method of detecting a substance, wherein the method includes functionalizing a plurality of sensors, wherein the functionalizing the plurality of sensors comprises depositing a first material using a piezoelectrically actuated pipette system, wherein the first material includes a polymer, a receptor, and a solvent, wherein the solvent comprises dimethylformamide. The method further includes evaporating a solution of the first material wherein a residue after the evaporation comprises a functionalized chemical. Additionally, the method includes introducing a control material to a first set of sensors of the plurality of sensors using the piezoelectrically actuated pipette system. Further, the method includes introducing a test material to a second set of sensors of the plurality of sensors using the piezoelectrically actuated pipette system, wherein the test material comprises an analyte. Moreover the method includes determining a difference between a first resonant frequency shift in the first set of sensors of the plurality of sensors and a second resonant frequency shift in the second set of sensors of the plurality of sensors.
