. There he developed paper-based systems capable of performing molecular recognition. In particular, Badu-Tawiah looked to develop macrofluidic platforms that could analyse for specific biomarkers. Unfortunately, the enzymes required to detect biomarkers on paper-based platforms are not stable and require careful storage.

Research and career

Badu-Tawiah was appointed assistant professor at the

in 2014. His research considers new mass spectrometry techniques for the detection of disease. Mass spectrometry offers several advantages over macrofluidic platforms, as they remain stable. To achieve this he makes use of cleavable ionic probes that can be used to perform

immunoassay An immunoassay (IA) is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody (usually) or an antigen (sometimes). The molecule detected by the immunoassay ...

s. These probes can be attached to antibodies and mounted to a flexible substrate for screening without refrigeration. He made use of wax ink to trace out the outline of the channels of the device, forming a waterproof barrier that separates that safely captures and stores the blood sample. Badu-Tawiah has worked on devices that can allow the early-detection of malaria and

Zika virus Zika virus (ZIKV; pronounced or ) is a member of the virus family ''Flaviviridae''. It is spread by daytime-active ''Aedes'' mosquitoes, such as '' A. aegypti'' and '' A. albopictus''. Its name comes from the Ziika Forest of Uganda, where ...

. In 2016 he demonstrated that these simple diagnostic tests were able to accurately diagnose whether someone was infected with malaria up to one month after blood was collected, and that patients could send them by mail to research labs. Alongside malaria diagnosis, the tests are capable of identifying the cancer antigens that are markers for cancers of the large intestine. Alongside disease detection, Badu-Tawiah works on novel analytical devices for photo- and electro-catalytic screening.
