Directing drug treatment to tumors is a hit-or-miss activity. Considerable research efforts are going into improving targeted drug delivery. A new approach centers on nanotechnology.

Bubble pen paves the way for improved technology

Austin - Scientists have created a "bubble pen," and the technique of bubble-pen lithography, to inscribe nanoparticles onto a surface.

Bones self-repair thanks to nanotechnology

University of Michigan researchers have created a polymer sphere capable of delivering a molecule directly into bone wounds. The molecule instructs cells at the injury site to repair the damage.

Nanotechnology creates new, super strong magnesium

Scientists have invented a new, super-strong and structurally light metal that possess extremely high specific strength.

Catch the dust, real gold as light as air

Zurich - A new type of gold has been created and it is as light as air. The new material takes the form of a foam and it is one thousand times lighter than mined gold, making the material the lightest form of the metal ever produced.

New method for treating pancreatic cancer

Oxford - Scientists may have found a new method for treating pancreatic cancer, and one which could lead to improved survival rates. The research is, so far, based on animal models.

New super glue only becomes sticky when crushed

Researchers in Japan have invented a new type of glue that is dry and non-sticky until it is crushed. Once broken up the substance acts like any other adhesive.

Nanoparticles used to boost tomato growth

Food scientists are keen to find ways to boost food production, and one way to create novel foods is through the use of nanotechnology. One area under review is tomatoes.
