Interest in the use of engineered nanomaterials (ENMs) as either nanomedicines or dental materials/devices in clinical dentistry is growing. This new review paper details the ultrafine structure, chemical composition, and reactivity of dental tissues in the context of interactions with ENMs, including the saliva, pellicle layer, and oral biofilm; then describes the applications of ENMs in dentistry in context with beneficial clinical outcomes versus potential risks.
Scientists have shown that gold nanotubes have many applications in fighting cancer: internal nanoprobes for high-resolution imaging; drug delivery vehicles; and agents for destroying cancer cells. A new study details the first successful demonstration of the biomedical use of gold nanotubes in a mouse model of human cancer.
Scientists used supercomputers to find a new class of materials that possess an exotic state of matter known as the quantum spin Hall effect. The researchers propose a new type of transistor made from these materials.
Atom probe tomography, a powerful atomic-scale microscopy and micro-analysis technique, allowed researchers to make out the enamel's nanoscale composition and structure. This research identified never-before-seen amorphous biominerals and how they contribute to both mechanical hardness and the resistance of enamel to acid dissolution.
New research looks at how to create various non-spherical particles by releasing droplets of molten wax into a cool liquid bath. The physics behind this research shows how a range of non-spherical shapes can be produced and replicated with many possible industrial applications.
The hand-held Raman spectroscopy probe enables surgeons, for the first time, to accurately detect virtually all invasive brain cancer cells in real time during surgery. The probe is superior to existing technology and could set a new standard for successful brain cancer surgery.
Imagine thousands of copies of a single protein organizing into a coat of chainmail armor that protects the wearer from harsh and ever-changing environmental conditions. That is the case for many microorganisms. In a new study, researchers have uncovered key details in this natural process that can be used for the self-assembly of nanomaterials into complex two- and three-dimensional structures.
Scientists present the synthesis and characterization of a new inorganic nanostructured functional material, BOA, comprising gold nanoparticles and oxoborates. It has the form of small building blocks composed of gold nanoparticles embedded in a polyoxoborate matrix.
