In a groundbreaking development, scientists at the University of Illinois Urbana-Champaign have engineered a microscopic “arm” made entirely from coiled DNA, capable of capturing COVID-19 virus particles. Dubbed the NanoGripper, this innovative tool holds immense potential for rapid virus detection, prevention, and even targeted drug delivery.
A Microscopic Defender against Viruses
Details of the NanoGripper and its capabilities were published in the prestigious journal Science Robotics on November 27. This remarkable device, resembling a tiny hand with four fingers and a palm, is designed to latch onto virus particles, including the COVID-19 adhesion protein. “The NanoGripper can perform rapid tests to detect the virus and prevent it from entering healthy cells,” the researchers explained.
Adding to its impressive capabilities, the NanoGripper is equipped with a unique sensor that can detect the virus within a mere 30 minutes. This rapid detection method boasts accuracy comparable to traditional molecular qPCR tests, offering a significant advantage in timely diagnosis.
From Nasal Spray to Cancer Treatment
The researchers envision a future where the NanoGripper is incorporated into an antiviral nasal spray, effectively preventing inhaled viruses from interacting with cells in the nasal passages. This innovative approach could revolutionize how we combat respiratory infections.
The potential applications of the NanoGripper extend far beyond COVID-19. Scientists believe it can be adapted to detect and capture other viruses, including HIV, influenza, and hepatitis B. Moreover, they envision using the NanoGripper for targeted drug delivery, a revolutionary approach to treating various diseases.
In the realm of cancer treatment, the NanoGripper could be programmed to capture cancer cells and deliver anticancer drugs directly to the tumor site, minimizing damage to healthy cells. “We hope to use this technology to treat cancer by programming the fingers to capture cancer cells and deliver anticancer drugs,” the researchers stated.
The development of the NanoGripper marks a significant advancement in nanotechnology and its potential applications in medicine.This tiny but powerful tool promises to revolutionize how we diagnose, treat, and prevent a wide range of diseases.

**World Today News Exclusive interview with Dr. [lead Researcher Name], University of Illinois Urbana-Champaign**
**World Today News:** Dr. [Lead Researcher Name], congratulations on the groundbreaking publication of your work on the NanoGripper in *Science Robotics*. This tiny DNA “arm” capable of capturing COVID-19 virus particles is truly remarkable. Could you tell our readers a bit more about how it works?
**Dr. [Lead Researcher Name]:** Thank you. We’re incredibly excited about the potential of the NanoGripper. Essentially, we’ve harnessed the power of DNA origami, a technique that allows us to fold DNA strands into complex three-dimensional shapes.
The NanoGripper resembles a tiny hand with four “fingers” and a “palm,” all made from these folded DNA strands. We’ve engineered these “fingers” to specifically latch onto the spike protein used by the COVID-19 virus to attach to human cells.
**World Today News:** This sounds like it might very well be a game-changer for COVID-19 detection and treatment. How could the NanoGripper be used in real-world applications?
**Dr. [Lead Researcher Name]:** Absolutely. We envision several potential applications.
Firstly, the NanoGripper could be incorporated into rapid diagnostic tests, offering significantly faster and more accurate COVID-19 detection compared to existing methods. Imagine a simple,at-home test that uses the nanogripper to identify the virus within minutes.
Moreover, we believe it might very well be used to prevent infection. Imagine coating masks or surfaces with NanoGrippers that capture virus particles, effectively creating a barrier against infection.
the NanoGripper could be used for targeted drug delivery. By attaching medications to the “palm” of the NanoGripper, we could deliver them directly to infected cells, increasing efficacy and reducing side effects.
**World Today news:** This is truly revolutionary. What are the next steps in your research?
**Dr. [Lead Researcher Name]:** We’re currently focusing on several key areas.
Firstly, we need to test the NanoGripper’s effectiveness in real-world settings.We’re collaborating with clinicians to explore its potential in diagnostic tests and antiviral therapies.
Secondly,we’re working on making the NanoGripper even more efficient and adaptable.We’re exploring ways to target other viruses and bacteria, and to refine the “gripping” mechanism for even greater precision.
we’re investigating the scalability of NanoGripper production so that it can be widely accessible and affordable.
**World Today News:** dr. [Lead Researcher Name], thank you for your time and for sharing this exciting breakthrough with our readers. The NanoGripper holds immense promise for a healthier future.
**Dr. [Lead Researcher Name]:** Thank you. It’s our hope that this technology can truly make a difference in the fight against infectious diseases.
