Researchers from the International Islamic University Malaysia (IIUM) have developed a tumor biosensing chip that can help determine the optimal chemotherapy dosage required for a cancer patient.

Developed by Prof. Anis Nurashikin Nordin and her team, the miniature chip uses cells derived from cancer patients to screen reactions to different drugs and dosages. The sensor measures the growth and death of the cancer cells electronically and the results are transmitted wirelessly in real time.

Currently, the chip is being tested with lung cancer patients and the research team hopes that it can be used to help cancer patients in the near future.

The chip is one example of the team's efforts to develop precise medical devices for personalized medicine and improving patient outcomes.

Anis and her team have also developed an ultra-sensitive biosensor for early dengue detection. The dengue sensor can detect the mass and electrochemical presence of non-structural protein, NS1, using a low-cost, portable and miniature sensor array. The ability to detect NS1 allows physicians to have an earlier diagnosis for dengue patients and thus prescribe immediate treatment.
