Biomedical electrochemical sensors for resource-limited countries

High-performance, low-cost point-of-care (POC) biomedical electrochemical sensors integrated with digital mobile technologies have emerged as the most promising innovations for quick and accurate diagnosis of the diseases that plague resource-limited countries. This work is a short review on key developments in the field of biomedical electrochemical sensing in the last two years with a special focus on four priority diseases (malaria, tuberculosis (TB), human immunodeficiency virus (HIV) infection and human papillomavirus (HPV) infections).
