Microfluidic Integration of Aperiodic Gold Nanoparticle Arrays for Local Refractive Index Sensing

Not Accessible

Your library or personal account may give you access

Abstract

We present microfluidic integration of a novel optical sensing technique based on distinctive structural color modifications in aperiodic nano-structures. The liquid-induced index sensitivity of the proposed devices is quantified by autocorrelation analysis in the visible spectral range.
