Innovative medical system technologies such as devices and methods used in the diagnosis and treatment of the cardiovascular system, Micro-weight meters and their applications, interactions of surface modified hollow fibers with plasma proteins are explored here. By using sensitive mass sensors, myocardial-derived proteins released in heart attack and rare tumor cells in circulation can be examined with microfluidic systems. The response of blood cells to foreign surfaces in artificial organs can be measured with mass sensitive sensors. There are ultrapure water device, biological safety cabinet, ultrasonic bath, heated mixer, multiple mixer, vortex mixer and similar basic laboratory equipment in the laboratory.
