Scientists create “smart” DNA drug that targets cancer cells with extreme precision

Scientists have created a programmable drug system that can zero in on cancer cells with unprecedented accuracy. Built from synthetic DNA, it only activates when it detects a precise combination of tumor markers, preventing damage to healthy tissue. The system can also deliver multiple drugs at once, potentially overcoming resistance. This marks a step toward medicines that behave more like smart, responsive machines inside the body.
