Published: March 6, 2025

In the past decades, conjugated polyelectrolytes (CPEs) have become prominent in sensing applications due to their unique properties, including strong and tunable light absorption, high sensitivity, water solubility, biocompatibility. Inspired by mammalian olfactory gustatory systems, CPE-based sensor arrays made significant strides discriminating structurally similar analytes complex mixtures for various applications. This review consolidates recent advancements arrays, highlighting rational design, controllable fabrication, effective data processing methods. It covers fundamentals of CPE fluorescence sensing, emphasizing design strategies array units techniques. The broad applicability is demonstrated across diverse domains, environmental monitoring (e.g., detecting metal ions explosives), medical diagnostics disease markers analyzing biological samples), food safety assessing freshness, quality, source products). Further, challenges future directions field are discussed inspire further research development this area.
