Groundbreaking improvement for early diagnosis of significant diseases

Report Post

South Korea – Sogang University Department of Mechanical Engineering Lee Jungchul – Kim Dong Choul joint research team developed hollow micro tube resonator mass sensor based on self–assembled silicon by using migration phenomenon of silicon surface molecules, which arose when annealing in 1,150 degrees Celsius.

This achievement has been announced on January 27, 2016 in Nano Letters, a significant academic journal in the Nano field.

The research team has investigated the fundamentals that are inside the silicon wafer which can materialize the cavity by running parallel to experiments of silicon surface molecule migration phenomenon and numerical value calculation. By using these manufactured joints and through oxidation of the surface inside, materialize the oxide shell within the scale of tens or even hundreds of nanometers to the desired thickness, and then developed hollow micro tube resonator mass sensor by using the method to remove surrounding silicones. Hollow micro tube resonator mass sensor that was developed made it possible to measure from a single level to high speed of nanoscaled body structures such as various nanoparticles and viruses/exosome that exist in liquid.

Professor Lee Jungchul said: “From the result of this research, by using label–free method, measured microscopic particles that circulate in the patient’s vain with specific disease so it is expected to make great deal of groundbreaking contribution towards early diagnosis of various important diseases” and added that “this suggested method can possibly be utilized infinitely for energy, environment, and fields of optics beyond precise physics-based sensor areas.”
