DNA nanotechnology clamping down on cancer-causing mutations

An international research team has built molecular 'clamps' out of DNA that offer a powerful new tool for identifying individuals with an increased risk of cancer. The clamp is capable of detecting genetic mutations, associated with cancer and other genetic diseases, with better specificity and affinity than more traditional techniques.

Graphene chemical sensor could unlock anesthesia's secrets

Researchers created an artificial chemical sensor based on one of the human body's most important receptors - one that is critical in the action of painkillers and anesthetics. In these devices, the receptors' activation produces an electrical response rather than a biochemical one, allowing that response to be read out by a computer.

Nanocellulose sponges to combat oil pollution

A new, absorbable material from Empa wood research could be of assistance in future oil spill accidents: a chemically modified nanocellulose sponge. The light material absorbs the oil spill, remains floating on the surface and can then be recovered.
