Resumo

Nitric oxide (NO) plays a crucial role in various physiological processes, making its detection and controlled release significant for both therapeutic and environmental contexts. Electrochemical sensors are widely used for NO detection due to their high sensitivity and real-time monitoring capabilities. However, challenges such as interference from other gasotransmitters, sensor degradation, and calibration difficulties-especially in complex biological matrices-hinder accurate NO measurement. This review discusses recent advancements in electrochemical NO detection, with a focus on the impact of complex biological matrices, calibration strategies, and sensor designs. The release of NO from nanoparticles, such as S-nitrosoglutathione (GSNO)-encapsulating chitosan nanoparticles, is used as a case study for improving NO detection accuracy. Future innovations in sensor technology and nanoparticle design are expected to expand the applicability of NO detection in personalized medicine and environmental monitoring. (AU)
