Abstract

Abstract : Inside Front Cover In article number 2100277, Lee, Jung, and co‐workers develop an ultrasensitive molecule detection platform for surface‐enhanced infrared absorption spectroscopy. Based on using a metamaterial absorber with 10 nm‐thick vertical nanogap processed via nanoimprint lithography and isotropic dry‐etching, a record‐high reflection difference detection signal for a 1‐octacanethiol monolayer molecule is achieved.
