“Disrupting medical care in Africa”

In the community of Gwagwa, Nigeria, Tope Agbana used his innovative diagnostics tool to screen 1,250 children. “We had already confirmed that the device works, but more data helps to improve it further and sheds light on community infection grades. Equally important, the results shock the leaders there. They now realise just how many children are ill. This tool changes mindsets.”

Main cause of death

As a post-doc researcher at the Faculty of Mechanical Engineering (ME) of TU Delft, Tope Agbana decided to explore better ways to detect malaria. It is the main cause of death amongst pregnant women and children, mostly due to poor diagnostics. “Conventional microscopy by highly trained microscopists is the standard diagnostic method. This is available in developed urban areas but not in remote impoverished areas.”

Agbana designed an automated smartphone-based optic diagnostics tool. It combined innovative optimisation of the smartphone’s optical technique with the integration of a smart algorithm. The TU Delft Global Initiative supported the concept with a PhD research position. Agbana developed the tool in cooperation with the Faculty of Industrial Design.

Impact driven

With the support of TU Delft, Agbana also started his company AiDx Medical. It shares research data and offers research opportunities for students. “And thanks to the NWO INSPiRED fund, I can still work as a part-time researcher at TU Delft.” For this, he collaborates with LUMC, the Universities of Ibadan and Lagos in Nigeria, and Cermel Gabon, a leading medical research centre.

“Our project is impact driven. My goal is to develop, produce and implement diagnostic devices to change the future of millions of children.” This entails extensive travel to Nigeria, often accompanied by TU Delft students. “You need actual boots on the ground to gather data and forge collaborations. And to talk to the people who are going to use the tool. Is this the best solution?”

Proper feeding

The screening Agbana recently conducted in Nigeria was for urinary schistosomiasis. According to WHO standards, 50 worms in a sample is evidence of a high infection load. “Many of the children had 2,000 worms or more. I wept when I saw this,” Agbana admits. He alerted a nearby NGO to start treatments. They were willing but couldn’t because, for the treatment to work, the children needed proper feeding first. So Agbana arranged for food. “Not for all of them, unfortunately: just 60 children. I cannot do research, pack my bag and go. That is not why I am here. I am here to make a difference.”
