Nanotechnology research finds a way to treat tumors with green tea

Delivering a drug to a targeted site in the body requires a ‘carrier’ — a compound that encases the drug. However, optimizing the drug-to-carrier ratio can be a major challenge. “This ratio is a stumbling block in carrier design because the carrier itself provides no therapeutic effect,” explains Jackie Ying. “Furthermore, high quantities of the carrier...

Sputtering start for flat materials

Two-dimensional materials have a whole host of exotic properties because they are just one atom thick. A*STAR researchers have now developed a method for creating large areas of atom-thin material for use in electronic devices ("Growth of wafer-scale MoS2 monolayer by magnetron sputtering"). Graphene, a single layer of carbon atoms arranged into a...

Lanthanide-organic framework nanothermometers prepared by spray-drying

A work in Advanced Functional Materials shows how spray-drying prepared MOF nanoparticles containing lanthanide metals may be used as nanothermometers operative over a wide range of temperatures, in particular, in the cryogenic range. The work was coordinated from the University of Aveiro (Portugal)...
