This Gold Nanoparticle Paint Changes Color Based on Touch

A team of chemists at the University of California, Riverside, recently had a happy accident. While experimenting with stringing gold nanoparticles together, they noticed that the gold kept changing colors from a bright blue to purple to red. Indeed, the more they touched it, the more the color changed. » 5/02/14 2:40pm 5/02/14 2:40pm

Gold Nanoparticles Give Plastic Skin Life-Like Senses

Human skin may very well be one of the world's most impressive sensor arrays. Able to detect temperature, pressure, touch and pain simultaneously, your skin's sensory receptors feed you a constant data stream about the environment around you. Now, researchers have given much of that sensing ability to plastic e-skin. » 7/09/13 11:23am 7/09/13 11:23am

Scientists Create Flat Breasts on a Chip for Breast Cancer Research

That's a breast on a chip. Why? Because though it looks like a slide, it actually accurately mimics the branching mammary duct system of a breast, where most breast cancers begin. That's key for cancer research since scientists can now test new approaches for treatment, like magnetic nanoparticles. It sounds insane: » 2/23/11 9:20pm 2/23/11 9:20pm
