A researcher from Kirinyaga University, Dr. Dickson Mwenda Kinyua from the School of Pure and Applied Sciences, working in collaboration with scientists Pietro Cucuta’s from the University of Cambridge, United Kingdom the team have developed a method that combines polarized light and a magnetic field to detect malaria parasites in blood samples. Unlike conventional microscopy, the new approach is label-free and does not require staining or chemical treatment, making it faster and easier to use significantly improving malaria diagnosis.
The technique relies on hemozoin crystals produced by Plasmodium parasites. When exposed to a magnetic field, these crystals align and alter how they interact with polarized light, producing measurable changes in image intensity and contrast. This enables not only detection but also precise measurement of parasite concentration and location in the sample.
Findings published in Biomedical Optics Express show that the method can reliably detect and quantify malaria signals in laboratory tests.
This breakthrough offers a more objective and consistent alternative to traditional methods, with strong potential to enhance early diagnosis, guide treatment decisions, and support large-scale screening, particularly in low-resource settings.
The research team is now preparing for clinical trials and working to simplify the system further, including integrating automated image analysis to improve accuracy and reduce reliance on expert interpretation. This remarkable achievement reflects excellence in research, innovation and global impact.
On behalf of the entire Kirinyaga University (KYU’s) fraternity, the office of the Vice Chancellor, and that of the Deputy Vice-Chancellor in charge of Academic, Research and Student Affairs, congratulate Dr. Dickson Mwenda Kinyua for his outstanding contribution to groundbreaking malaria detection research.
