Researchers use nanoscale zinc oxide structures to detect anthrax
A new approach promotes the use of zinc oxide nanomaterials as signal enhancing platforms for rapid, multiplexed, high-throughput, highly sensitive, DNA sensor arrays. Engineered nanoscale ZnO structures can be effectively used for the identification of the biothreat agent, Bacillus anthracis, by successfully discriminating its DNA sequence from other genetically related species.
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.
