Golden vehicle for drug delivery has hidden costs

One of the biggest ideas in treating disease involves material so small it isn't even visible. Miniscule gold particles – the size of several atoms – are being touted as vehicles to send drugs exactly where they are needed ...

Gold 'nano-drills'

Spherical gold particles are able to 'drill' a nano-diameter tunnel in ceramic material when heated. This is an easy and attractive way to equip chips with nanopores for DNA analysis, for example. Nanotechnologists of the ...

Hot nanoparticles for cancer treatments

Nanoparticles have a great deal of potential in medicine: for diagnostics, as a vehicle for active substances or a tool to kill off tumours using heat. ETH Zurich researchers have now developed particles that are relatively ...

Gold nanoparticles give an edge in recycling CO2

(Phys.org) —It's a 21st-century alchemist's dream: turning Earth's superabundance of carbon dioxide—a greenhouse gas—into fuel or useful industrial chemicals. Researchers from Brown have shown that finely tuned gold ...
