Nanotechnology in dentistry - applications, hazards, benefits

There appears to be many potential benefits to patient outcome from using nanotechnology in dentistry. The benefits include new materials for preventative health care using dentifrices that are either antimicrobial and/or have some restorative properties for the enamel and dentine. A new review paper in ("Review of Nanomaterials in Dentistry: Interactions...

Scientists establish the source of the peculiar stability of the structures forming carbon nanotubes

The source of the peculiar stability of the structures forming carbon nanotubes has been established by researchers from the RIKEN Elements Chemistry Laboratory ("n-Plane Aromaticity in Cycloparaphenylene Dications: A Magnetic Circular Dichroism and Theoretical Study"). Carbon nanotubes are made of hoop-like macrocycles called cycloparaphenylenes (CPPs),...

Frst successful demonstration of the biomedical use of gold nanotubes in human cancer model

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. The study, published today in the journal ("Engineering Gold Nanotubes with Controlled Length and Near-Infrared Absorption for Theranostic Applications"),...
