Liberian Scientist Dougbeh Nyan granted US patent for rapid diagnostic test

LIBERIA –Africa’s renowned Infectious Disease Scientist Dr. Dougbeh Christopher Nyan has been awarded a second patent by the United States Patent and Trademark Office (USPTO) for inventing a rapid diagnostic test that detects multiple infections in less than an hour.

Dr. Dougbeh Christopher Nyan has been issued a patent for his scientific invention dubbed “Methods for Rapid Detection and Identification of Viral Nucleic Acids” of infectious pathogens that is viral-specific and applicable to other pathogens in detecting genetic materials such as the RNA and DNA.

He also discovered an innovative Rapid Multiplex Real-Time Isothermal Amplification Method that specifically detects and simultaneous identifies multiple viral infections in less than an hour using one test.

Dr. Nyan received his first patent from the United States Patent and Trademark Office in 2018 for his invention of the rapid multiplex isothermal amplification diagnostic test which relates to the simultaneous detection and identification of pathogens.

Dr. Dougbeh Chris Nyan’s Multiplex Diagnostic Test is easy to perform, portable and can be used globally as well as affordable for resource challenged settings around the world.


In addition, the test can detect and differentiate infections causing infectious diseases since several infectious diseases may have similar clinical symptoms like HIV, Ebola, Malaria, the Coronaviruses, Dengue, Hepatitis viruses and many more.

Chief Medical and Scientific Officer of Shufflex Biomed Dr. Nyan acknowledged that the new patent is a milestone achievement of his scientific team’s hard work and innovation in diagnostics.

The second patent adds to Shufflex Biomed’s portfolio and ultimately increases the value of the start-up to a multimillion-dollar company as the Shufflex diagnostic kits are at the pre-production stage.

He said that the second patent by the United States Patent and Trademark Office adds to team’s arsenal of tools in detecting and combating infectious diseases, epidemics and pandemics on the African continent as well as the world at large.

I am very thankful to the governments of the US and Germany for my medical education, scientific training, and urge African governments to create an enabling environment that will utilize and promote science and technology on the continent,” he added.

Earlier on, he was honored with the 2017 African Innovation Special Prize for Social Impact winner and his scientific works have been published in reputable scientific journals such as Nature, the International Journal of Infectious Disease, Clinical Infectious Diseases and Neuropeptides
