Attaching biomolecules to carbon nanotubes

Among the many potential biology-related applications proposed for carbon nanotubes (CNTs) are high-sensitivity biosensors and bio-fuel cells. In order to create the synergy between the biomolecules and CNTs required to realize these applications, biomolecules, such as proteins and DNAs, must be connected to the CNTs.

Towards single-particle laboratories

Researchers at Cornell University have developed a novel quantitative nanoparticle-based sensor of chemical concentrations based on organic dye molecules covalently integrated into the matrix of silica nanoparticles. This is the first work that implements an optimized core-shell architecture for such sensor particles.

Humidity sensing by glass-ceramic nanocomposites containing silver

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.

Carbon/copper nanocomposites as novel, low-cost sensor materials

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.
