University of Illinois researchers create DNA NanoGripper to combat deadly viruses

In Champaign, Illinois, a team of scientists from the University of Illinois Urbana-Champaign has developed an innovative tool known as the DNA NanoGripper. This groundbreaking technology aims to assist in the detection and isolation of viruses, including SARS-CoV-2, which is responsible for COVID-19. The NanoGripper is a minuscule device crafted from a single strand of DNA, designed to mimic the gripping capabilities of the human hand and bird claws. It employs flexible fingers equipped with DNA aptamers that specifically bind to molecular targets, such as the spike proteins found on the SARS-CoV-2 virus. The project was spearheaded by Xing Wang, a professor in bioengineering and chemistry. He and his team aimed to create a nanoscale robot that could perform functions previously unseen in the biomedical field. This involved the innovative use of DNA for its strong, flexible properties, allowing for a unique design that minimizes complexity while maximizing utility. The researchers believe their design can lead to new methods for highly-sensitive rapid detection of viral particles, providing further insights into the behavior of viruses and their interactions with human cells. In terms of potential applications, the NanoGripper technology transcends COVID-19 detection. Researchers advocate that, with further development, it might also be used to target other viruses such as HIV and could even extend to applications in cancer treatment. The prospect of utilizing nanoscale robotics in medicine signifies a promising future, as current methods may be limited in sensitivity and efficacy, particularly in the rapid detection and treatment of viral infections. The possibility of targeted drug delivery through such innovations represents a significant advancement in the biomedical sciences. Overall, the DNA NanoGripper developed by the University of Illinois teams not only showcases an exciting scientific achievement but also opens avenues for future research in virus detection and medical advancements. As the research techniques improve, the implications for health technology and virology may be profound, leading to improved detection methods and treatment strategies for viral infections.
