This review highlights the integration of electrochemical methods and nanomaterials for water quality monitoring, improving PFAS detection using microfluidic networks and aptamers.
MXenes achieve picomolar affinity and rapid preconcentration of PFAS through biomimetic binding architectures. It also details the mechanism by which CRISPR-Cas12a, guided by PFAS-specific aptamers, enables single-molecule discrimination with attomolar sensitivity. Finally, this review paper demonstrates how microfluidic networks orchestrate this synergy, miniaturizing the entire assay into a portable, multiplexed platform that reduces analysis time from hours to minutes. Synergistically unifying breakthroughs in nanomaterials, synthetic biology, and lab-on-a-chip design, this work provides both a methodological blueprint for ultrasensitive PFAS sensors and a relevant roadmap for implementing proactive, decentralized water quality monitoring.
