1. A surface enhanced Raman spectroscopy (SERS) calibration curve generating system, comprising: a SERS sensor, including: a substrate; and a plurality of sensing members formed on the substrate, each of the sensing members including a plurality of SERS signal amplifying structures; an inkjet dispensing device to dispense different concentrations of a solution including a known analyte of interest onto the respective sensing members to form a concentration dependent array; an unknown solution to be introduced to at least partially cover at least some of the plurality of SERS signal amplifying structures prior to forming the concentration dependent array; a Raman spectrometer to interrogate the concentration dependent array; a processor operatively connected to each of the inkjet dispensing device and the Raman spectrometer; and computer-readable instructions embedded on a non-transitory, tangible computer-readable medium and executable by the processor, the computer-readable instructions to automatically generate an intensity profile as a function of concentration for the concentration dependent array.
