High‐Precision Multiplex Chemical Sensors with Pattern‐Recognition Capability via a Letter Printing‐Inspired Transfer Method

ABSTRACT Graphene‐based chemical sensors offer high sensitivity owing to exceptional charge transport and a large surface‐to‐volume ratio, yet reliable discrimination across diverse analytes remains challenging. In this study, a letterpress‐inspired, one‐step transfer‐printing st...
