Description

Abstract

Herein we demonstrate the surface plasmon resonance (SPR) refractometers based on smart phone platforms. The optical element used in this system is a single disposable device, which is configures to use conditioned illumination and optical detection from smart phone cameras. The SPR sensing element is fabricated by a soda lime glass slide coated with 50 nm gold film covered by the custom made epoxy resin flow cell. The performance of the smart phone-base SPR refractometers was evaluated by detecting the ethanol/water solutions with different concentrations ranging from 0% to 40% with 10% interval. The results demonstrate that our smart phone-base SPR refractometers is feasible to measure the refractive index of liquid sample and offer an attractive possibility in many applications such as health and environment monitoring.
