The tweezers grab a piece of target DNA and release it on-demand using a controlled series of hydrogen bonding and pH changes. The process of getting the tweezers to grasp and release. This is the first one that can grasp and release, as there have been other developments in this area. I’m not exactly sure on how the technology will be used, but the fact that it can be done is amazing, protein tweezers. BD
Researchers in China writing in Journal of the American Chemical Society are reporting development of a new DNA "tweezers" that are the first of their kind capable of grasping and releasing objects on-demand. The microscopic tweezers could have several potential uses, the researchers note. Those include microsurgery, drug and gene delivery for gene therapy, and in the manufacturing of nano-sized circuits for futuristic electronics. Zhaoxiang Deng and colleagues note that other scientists have developed tweezers made of DNA, the double helix molecule and chemical blueprint of life. Those tweezers can open and close by responding to complementary chemical components found in DNA's backbone. However, getting the tweezers to grasp and release objects like real tweezers has remained a bioengineering challenge until now.
