Caption : Figure S1: PWV Dependence on Bulk Refractive Index. Reflection spectrum (left) and label-free images of a PC surface with distilled water (upper left) and isopropyl alcohol (upper right) covering its surface. The PWV shifts from 620.52nm for water to 625.02 nm for isopropyl alcohol.

Caption : Figure S2: Time-stability of PC Resonant Wavelength. The average peak wavelength value (PWV) of background medium and the standard deviation. F-12 media was deposited in a PDMS well and incubated on the sensor surface. Minimal PWV shifting of .12 nm was observed over a period of 12 hours, with a standard deviation of .09 nm over the .9 m2 measured area.
