Using PDMS Plasma Cavity SERS Substrate for the Detection of Aspartame

<div>Curve of relationship between concentration (0.005–0.05 mg/L) of aspartame aqueous solution and characteristic peak intensity. The error bars represent the standard deviation of measurements for 12 concentrations in three separate sample runs (<i>n</i> = 36).</div>
