Porphyrins and related macrocycles have been intensively exploited as sensing materials in
chemical sensors, since in these devices they mimic most of their biological functions, such …

Dissolved oxygen is an important index to evaluate water quality, and its concentration is of
great significance in industrial production, environmental monitoring, aquaculture, food …

The past, present, and future of the application of self-assembled monolayers (SAMs) in
electroanalytical chemistry is reviewed. SAMs for electroanalytical applications have been …

Terrestrial life may be carbon-based, but most of its mass is made up of water. Access to
clean water is essential to all aspects of maintaining life. Mainly due to human activity, the …

A sensitive electrochemical sensor has been fabricated to detect ultratrace nitroaromatic
explosives using ordered mesoporus carbon (OMC). OMC was synthesized and …

The ever-increasing demand for accurate, miniaturized, and cost-effective gas sensing
systems has eclipsed basic research across many disciplines. Along with the rapid progress …

Dissolved oxygen (DO) usually refers to the amount of oxygen dissolved in water. In the
environment, medicine and fermentation industries, the DO level needs to be accurate and …

The determination of oxygen concentration plays a crucial role in many fields, such as
industrial production, environmental monitoring, food and drug safety, and clinical medicine …

The application of porphyrin metal–organic frameworks (MOFs) as a ratiometric
electrochemical sensing platform is still unexplored. In this paper, we report a ratiometric …

Conventional electrochemical dissolved oxygen (DO) sensors are expensive as they use
platinum in their construction. In addition, these sensors biofoul when used in natural or …
