UNIGE DNA System Targets Cancer with Logic Gate Precision

Researchers at the University of Geneva (UNIGE) have developed a programmable drug-delivery system using synthetic DNA ^[1]. This "smart" technology identifies specific combinations of tumor markers to release medication directly into cancer cells ^[2]. The breakthrough ensures that powerful drugs are only activated upon contact with malignant tissue, leaving healthy cells unharmed ^[3]. The delivery system operates using "AND gate" logic, similar to a computer processor ^[1]. It requires multiple markers to be present before the drug is released, which increases the accuracy of the treatment ^[2]. Experts believe this method could significantly improve precision cancer therapy by reducing side effects ^[3].
