Humidity is a measure of the moisture content of an environment. Control of humidity is thus essential for maintaining the desired level of moisture in an enclosure be it in a hospital or in a semiconductor-processing unit or in a laboratory. For humidity control an efficient sensor is an absolute necessity.
Researchers in Switzerland succeeded in the large-scale production of carbon-coated copper nanoparticles. These carbon/copper nanocomposites could be used as novel, low-cost sensor materials and offer a metal-based alternative to the currently used brittle oxidic spinels or perovskites.
A comprehensive overview of the main concepts behind the development of nanosensors and the most relevant applications in the field of environmental analysis.
