Motorized molecules driven by light to cut into cancer cells

Researchers have developed a novel technique where molecules would be motorized using light and these would be used to drill holes in the membranes of individual cells such as the cancer cells. This could bring the treatment molecule into the cancer cell directly and cause them to die.

Nanomaterial wrap for improved tissue imaging

Researchers at Tokai University describe in Advanced Materials how wrapping biological tissue in a nanosheet of a particular organic material results in high-quality microscopy images. Application of the wrap prevents the sample from drying out, and hence from shrinking, enabling larger image-recording times.

Potentially harmful nanoparticles found to be present in infant formula products

The study commissioned by Friends of the Earth (FoE) has found that six out of six infant formula samples tested contained nanoparticles, which are believed by FoE to be harmful. However the potential health risks of nanoparticles are disputed by others, who claim there is insufficient evidence to support this.
