Sampling devices with essentially impermeable and non-porous reservoir surfaces

Abstract

A sampling device is disclosed, including a substrate, a reservoir surface disposed on at least a portion of the substrate and configured to retain a liquid, the reservoir surface having a reservoir surface area and being formed of a reservoir surface material, and a Taylor cone emitter portion. The reservoir surface is essentially impermeable. The reservoir surface is essentially non-porous. The sampling device has a decreased loading time to target analyte saturation relative to an otherwise identical comparative sampling device having at least one of a permeable reservoir surface or a porous reservoir surface.

Dependencies are inferred from the claim text.
