DNA origami: the future of delivery system

A group of researchers from Arizona state university has mastered the art of making origami using DNA. It is not as easy as folding papers, as the DNA backbone is negatively charged and structural constraints must be considered in designing a feasible model.

DNA origami: the future of delivery system

It is fascinating to see how DNA can now interact to form unreal structures. This finding shed light on how it can be used to deliver drugs as a DNA cage. But how would the immune system see the foreign DNA lying around in the cytosol?
