Abstract :
We report the first real-time biomechanical measurement of DNA bundle degradation in stable condition when exposed to a therapeutic radiation beam and a theoretical model to describe DNA damages. The Silicon Nano Tweezers and their new microfluidic system endure the harsh environment of radiation beams and still retain molecular-level accuracy. This result paves the way for both fundamental and clinical studies of DNA degradation under radiation for improved tumor treatment.
