Abu Dhabi: Researchers at NYU Abu Dhabi have made a significant breakthrough in COVID-19 testing with the development of a new rapid testing method using an adhesive bandage. This innovative bandage relies on gold nanoparticles to quickly detect immune antibodies in the bloodstream, providing a cost-effective and user-friendly solution for identifying infected individuals and monitoring the spread of the virus.
The bandage targets two specific antibodies, IgM and IgG, which are naturally produced as a response to SARS-CoV-2 infection. By detecting these antibodies, the bandage serves as a valuable biomarker, enabling rapid and accurate diagnosis. The technology can also be easily modified in the future to detect antibodies specific to other emerging pathogens, making it highly adaptable for use in potential pandemics.
The testing process is simple and can be carried out at home. Users apply the adhesive bandage to a pinprick fingertip, similar to a regular bandage used to cover wounds. The bandage utilizes nanotechnology-based gold nanoparticles that are engineered with antigens unique to SARS-CoV-2. These antigens bind specifically to the IgM and IgG antibodies, triggering a color change within minutes. This color change indicates the individual’s infection status, whether they are not infected or have early immune, active immune, or immune response.
The affordability and disposability of the bandage make it a promising solution for large-scale detection and screening. It can be used in various settings, including homes, public facilities, and rural regions with limited access to sophisticated testing facilities.
The NYU Abu Dhabi research team, led by Associate Professor of Mechanical Engineering and Bioengineering, Mr. Mohammad Qasaimeh, detailed the testing technology in a paper published in the journal Microsystems and Nanoengineering. This breakthrough has the potential to revolutionize COVID-19 testing and contribute to more efficient and accessible healthcare solutions in the fight against the pandemic.
