Why It Matters

Analytical Chemistry and Sensors enables precise detection in environmental monitoring, medical diagnostics, and industrial processes through technologies like fluorescent nanosensors and potentiometric sensors. Fujishima and Honda (1972) demonstrated electrochemical photolysis of water at a semiconductor electrode, achieving 32,912 citations and laying foundations for photoelectrochemical sensors used in oxygen measurement and energy applications. de Silva et al. (1997) reviewed signaling recognition events with fluorescent sensors, cited 6,887 times, supporting developments in ultrasensitive cancer detection via peptide-based sensors as noted in recent news. Wearable smart chemical sensors, developed by TDA Research, Inc. for the Department of Homeland Security, provide inexpensive detection of chemical threats. CRISPR-based sensing highlighted in ACS Sensors special issues advances biosensors for rapid pathogen detection.
