Responsive material could be the ‘golden ticket’ of sensing




A new responsive material ‘glued’ together with short strands of DNA, and capable of translating thermal and chemical signals into visible physical changes, could underpin a new class of biosensors or drug delivery systems.

Researchers from the University of Cambridge have developed a new self-assembled material, which, by changing its shape, can amplify small variations in temperature and concentration of biomolecules, making them easier to detect. The material, which consists of synthetic spheres ‘glued’ together with short strands of DNA, could be used to underpin a new class of biosensors, or form the basis for new drug delivery systems.
