US Patent Issued to Liberian Scientist for Multiplex Infectious Disease Test

Dr. Dougbeh Christopher Nyan, M.D. (Scientist, Inventor, Medical Doctor and Activist)

The United States Patent and Trademark Office (USPTO) has issued US Patent No. 10,072,309 to Dr. Dougbeh Chris Nyan for his invention of a rapid multiplex pathogen diagnostic test that detects and identifies many infections in less than an hour.

Nyan is a Liberian medical doctor and scientist with expertise in infectious diseases and developing simple diagnostic tests for hard-to-reach settings and the global healthcare community.

This proprietary technology is applicable to developing pathogen diagnostic test kits for simultaneous detection and differentiation of multiple infectious such as HIV/AIDS, Hepatitis B, C, and E, West Nile virus, Ebola, Malaria, Dengue, Lassa and Yellow fever viruses, West Nile virus, Zika, and a variety of other infectious. The technology was published in Nature-Scientific Reports and the International Journal of Infectious Diseases.

Accordingly, the Nyan-Test is capable of detecting at least 3-7 pathogens in less than an hour, thus enabling healthcare workers to identify infections and carry out specific treatment. The test is affordable, portable, cuts down detection time, and applicable to settings in the developing countries and vulnerable communities of the developed world. It can be used in early diagnosis, monitoring of the safety of blood products, and surveillance to prevent epidemics.

Nyan, a Mano name for second boy in a family, has intimated that his “invention will be produced to serve suffering humanity and contribute to the global fight against infectious diseases.”

His career in medicine and research spans over twenty-five years. He studied Zoology and Chemistry at the University of Liberia from where he was expelled by the military government of Samuel Doe in 1988 for his advocacy for democracy, press freedom, and human rights. He was arrested and imprisoned by the military government for his pro-democratic advocacy and later exiled and lived in Germany where he studied human medicine at the Charité Medical Faculty of the Humboldt University of Berlin.

He worked as scientist in infectious diseases at the US National Institutes of Health, the University of Pennsylvania School of Medicine, Naval Medical Research Center, the US Food and Drug Administration and in the biotechnology industry.

Dr. Nyan testified before the US Congress on September 17, 2014, during the Ebola outbreak in West Africa. He advocated for a sustained and coordinated support to the Ebola-affected countries of Liberia, Sierra Leone, Guinea, and Nigeria. He requested the U.S. Government to send health experts and technical personnel to the affected region.

He also advocated for the establishment of an African Center for Diseases Control and Prevention, now in Addis Ababa, Ethiopia.

In recognition of his invention, Dr. Nyan has received numerous awards and recognition including the prestigious 2017 African Innovation Award Special Prize for Social Impact, the Lifetime Achievement Award in Science and Medical Research form the Ward Fund, and the Science and Research Award from the Liberian Award.

Nyan’s multiplex test was also recognized as one of Top 3 Innovations by the Africa 2017 Business Forum in Egypt and recently exhibited as one of Top 50 Innovations at the Africa Innovation Summit 2018 in Kigali, Rwanda.

Nyan’s patented technology comes amid the rise of infectious diseases in vulnerable settings in Africa, Asia, and South America and disease re-emergence in neglected communities of the United States and other developed countries.

The Nyan-Test projects to be life-saving and contribute to quality healthcare globally, while providing a multi-billion dollar investment opportunity to the global business community. Dr. Nyan’s biotech startup, Shufflex Biomed, is now raising funds to produce version 2.0 of the test and carry out field studies in Africa and South America.


  1. When will all this by-election stop. It is a waste of the people’s money. $1.2 million dollars can be used to patch up the holes in the streets of central Monrovia, especially, from Vai Town to st. Paul bridge or renovate some section of JFK hospital, or provide funding for the extension of the power line from V.P junction on Robertsfield Highway towards Marshall. We could use that money to put street lights on the Robertsfield highway or put people on the electric grid. I can go on and on about what to do with that money. My suggestion about filling vacant seats in the House or Senate is to have the Superintendent appoint someone to finish the term for that person who created the vacant seat. Let’s amend the Constitution to this effect. I don’t know why those Representatives were allowed to run for the office of Senators when they had not completed their terms as Representatives in the first place? What will we do , “God forbid” if something happens to 2 or more members of either the Senate or the House of Representative? Are we going to have another bi-election to fill those seats? Let us please put a stop to this.

  2. My heart lifts; yes we can. Just some opportunity and the Liberian is just as capable. Thanks Dr. Nyan, you make us proud.

  3. Did anyone from this publisher know the timeline of Doe’s administration? Was Liberia ever under a Military Government in 1988? I appreciate Dr. Nyan’s work. However, allowing the publisher to twist historical facts defeats and overshadows his lifetime achievements. They must be very shame and uneducated!

  4. After decades, Liberia has positively impacted the globe; thanks 🙏🏾 doctor NYAN, your effort and dream are a monumental success for both You and Mama Africa at large.


  5. Hats off Dr. Nyan for your great contribution to mankind and for making Africans, particularly Liberians,
    proud. What a great man you are !!!!!

  6. It is with pride and honor I pen down these words in admiration of a Celebrated Liberian Doctor. It is not only because you hail from Liberia, but because you have used your God-given Talent and Wisdom to directly improve the Health Sector of Africa.
    Doctor Nyan, we appreciate you greatly and are very proud of your achievements. You have started a trend of great Liberian Scientists and Inventors.
    We the student reading the sciences will forever look up to you as a Role Model and beacon of hope for the Health Care Delivery Service in Liberia and Africa at-large.
    Hats off to you Doc.

  7. Nyan, your contribution to humanity has earned you a place in the hearts of all people, especially Liberians. You deserve the recognition fo using your gift to benefit man you will not only receive the monetary that you invention brings but also the blessings of God for your help.

  8. Dr. Nyan:

    You are one bright spot in the sea of all of us, Liberians. You have done something very very Special to make us proud.

    Nobody likes to get sick but when the inevitable happens and I find myself in a hospital, I will ask for the Nyan-Test or recommend it for friends and family members.

    My way of being proud and showing appreciation for your invention.

    Thank you!

  9. Wow!

    It brings great joy and pride to my heart indeed to read this impressive recital about a Liberian.
    Though not many, I know Liberians always excel in whatever they do.
    I wish Liberia had the infrastructure and fund to fully benefit from all incentives to be derived from this invention. The USA will again reap most of the benefits, and Dr. Nyan and some members of his family will singularly benefit.

    Proud of you Doc! Let the sky remain your limit.

  10. Read a little bit about Nyan. Nyan’s invention was almost snatched away from him because he’s a black guy. A little over two years ago, a US Congressman had to get involved in order for Nyan to be internationally recognized. Enter his full name in your browser.

  11. Like most of the black inventors, like Granville T. Woods who spent most of his life fighting to patent his invention to no avail until he died poor, leaving the white guys to take the credit for things they did not invent.

    When are we going to learn to development and customize of technologies?
    We can start by voting in good leaderships in Africa, not the puppets we have ruling us in nearly all African countries except for a few like Ghana, Nigeria, Rwanda, etc.

  12. Or try Arthur Lewis, the first full-time black Economics professor at a British university. He died before he received his Nobel Prize in Economics. Very unusual one might say, yes indeed! Just read about him briefly. Enter his name in your browser.
