Brighter future for carbon dots

A variety of approaches have been used to make C-dots, but most require coating of the particles with other molecules to achieve useful luminescence. Now, work led by Amita Pathak at the Indian Institute of Technology has produced water-soluble C-dots that selectively emit light across the entire visible range without any surface coating.

Under-twisted DNA origami delivers cancer drugs to tumours

Scientists at Karolinska Institutet in Sweden describe in a new study how so-called DNA origami can enhance the effect of certain cytostatics used in the treatment of cancer. With the aid of modern nanotechnology, scientists can target drugs direct to the tumour while leaving surrounding healthy tissue untouched.
