This is the first comprehensive review on methods and materials for use in optical sensing of
pH values and on applications of such sensors. The Review starts with an introduction that …

The crucial recognition events of chemistry, biology, and materials science occur in a much
smaller world than the one we are accustomed to. Information about these events can be …

Because their chemical and physical properties may be tailored over a wide range of
characteristics, the use of polymers is finding a permanent place in sophisticated electronic …

Cations and anions play an important role in a wide range of chemical reactions, including
biological metabolism as well as many other processes. 1-6 For the purpose of detection …

The maturation of nanotechnology has revealed it to be a unique and distinct discipline
rather than a specialization within a larger field. Its textbook cannot afford to be a chemistry …

A new optical sensor based on covalent immobilization of a newly synthesized calcium-
selective, long-wavelength, fluorescent indicator has been constructed, with a response …

Optical fibre nanowires and microwires offer a variety of enabling properties, including large
evanescent fields, flexibility, configurability, high confinement, robustness and compactness …

Scanning Tunneling Microscopy and its Application presents a unified view of the rapidly
growing field of STM, and its many derivatives. A thorough discussion of the various …

The first sol− gel-based, ratiometric, optical nanosensors, or sol− gel probes encapsulated
by biologically localized embedding (PEBBLEs), are made and demonstrated here to …

This article provides a brief review on the development and applications of optical and fiber-
optic pH sensors in the 1990s. Various methods and materials for immobilization of pH …
