The primary objective of this project is to develop a device to screen for substandard anti-malarials and antibiotics, thereby improving adverse maternal and neonatal health outcomes with respect to malaria and sepsis. To date, there is no device to test counterfeit and substandard drugs in the field thoroughly. To this end, we propose PharmaCheck, a user-friendly, cost-effective, contextual and high-throughput device capable of quantitatively measuring active ingredient concentration and drug release profiles to quickly and accurately screen for spurious medicines.
