Nucleic Acid Integrated Technologies for Electrochemical Point-of-Care Diagnostics: A Comprehensive Review

The need for routine and immediate healthcare monitoring has inspired near-patient testing or in other words point-of-care testing (POCT). Therefore, POCT can be defined as laboratory tests that are performed at the patient's bedside or in the immediate vicinity of the incident. Among many POCTs, nucleic acid-based testing has attracted enormous attention for the diagnosis of important genetic, inherited and infectious diseases such as cancer and coronavirus. In this review, we outline the integration of nucleic acids into the remarkable electrochemical point-of-care diagnostics including microfluidic, paper and smartphone-based approaches, CRISPR/Cas and liquid biopsy related systems and DNA damage monitoring.
