RESEARCHERS USE DNA TO BUILD TOOL THAT MAY SHINE LIGHT ON CANCER

摘要

The researchers' nanosensor measures pH variations at the nanoscale determining how acidic (a higher pH level) or alkaline (a lower pH level) it is. Many biomolecules such as enzymes and proteins are strongly regulated by small pH changes. These changes affect in turn biological activities such as enzyme catalysis, protein assembly, membrane function and cell death. There is also a strong relation between cancer and pH.
