The development of nanomaterials for imaging and drug delivery has been of great interest to the field. Here, the authors synthesized multifunctional enzyme-responsive hydrogels with self-assembling quantum dots for nucleic acid and drug delivery as well as having imaging capability.
DNA origami nanostructures were utilized to replicate a seed pattern that resulted in the growth of populations of nanostructures. Exponential growth could be controlled by environmental conditions depending on the preferential requirements of each population.
This month marks ten years since the general principles of DNA origami were established, a technique that changed the field of DNA nanotechnology and that promises new physical and biomedical applications.
