Not Accessible

Your library or personal account may give you access

Abstract

A novel optical sensing technique based on distinctive colorimetric signatures and spectral shifts of deterministic aperiodic arrays is demonstrated by protein monolayer sensing in the visible spectral range using inexpensive dark-field spectroscopy and autocorrelation analysis.
