Abstract Click to copy section linkSection link copied! Artificial solid-state nanochannels have attracted significant interest as promising nanofluidic tools for ion/molecule detection, DNA sequencing, and biomimetic applications. In this work, we designed an aspartic acid-rich peptide, KD5 (Lys-Asp5, KDDDDD), via a green tag-assisted approach.

Abstract Click to copy section linkSection link copied! Nanochannel-based sensors offer exceptional sensitivity, selectivity, and real-time response for ionic analysis, yet achieving advanced recognition of heavy metal ions remains challenging due to the limitations of conventional single-layer surface modification.
