Cambridge, MA – Scientists at the Massachusetts Institute of Technology (MIT) have made a significant breakthrough in affordable healthcare by developing a disposable DNA sensor that can quickly detect diseases such as cancer and HIV within minutes.
Costing only 50 cents, the sensor utilizes the CRISPR Cas12 enzyme to recognize disease-specific genetic markers from non-invasive samples like saliva, urine, or nasal swabs. Upon detecting the target DNA, the device produces a real-time electrical signal, removing the need for complicated lab equipment.
Made from gold leaf and DNA strands, the compact device requires no refrigeration and remains stable for up to two months, even in warm environments. These qualities make it especially useful for low-resource areas and at-home testing.
MIT’s researchers are preparing to start field trials, aiming to transform early diagnosis and monitoring of critical diseases worldwide. If successful, this innovation could revolutionize personal and global health by providing fast, affordable, and dependable testing directly at home.
