Professor Lee Jung-chul developed a precision balances that can measure live cells
- With simple process, expects widely spread the use in industry fields-
Department of Mechanical Engineering Professor Lee Jung-chul’s research team developed ‘glass capillary resonator’ which is a delicate scale that can measure mass of single cell or micro particle living inside the solution. Glass capillary is made up of thin pipe shape made up of glass, resonator means an equipment or system that induces phenomenon to vibrate with structure with external force on natural frequency.
Glass capillary resonator which the research team developed shows outstanding degree of accuracy similar to the level of MEMS Sensor with just general process without semiconducting process. MEMS Sensor is a sensor that measures force, vibration, temperature, weight and so on through micromachining similar to the micro level. Therefore, with the development of this resonator can solve the problem of complex operation, overhead costs and expensive manufacturing facilities. Professor Lee Jung-chul said, “We developed glass capillary resonator that can precisely measure the weight of single cell or fine micro particle as the size of a millionth of a particle. And explained the meaning of research, “Due to inexpensive and simple production method, it is expected to widely spread to not just in life science research but also in overall industry.
This research was carried out with the support from Ministry of Science and ICT Basic Research Project(Individual research), and as the result, published in Scientific Reports which is an international academic journal.
