Research summary

 On the medical, pharmaceutical and public health area, it is necessary to measure biological samples including proteins, saccharides, pathogenic materials and bacteria. However, traditional measurement methods include complex steps and need sophisticated expertise, expensive devices and long measurement time.
 To solve this problem, Professor Iida developed the microflow-mediated light-induced acceleration system (LAC-SYS). It uses the phenomenon that the irradiation of light on the photoresponsive material (like substrates and particles) induces the accumulation of biological material including proteins around the focal point. It has dozens or hundreds of times higher sensitivity than the conventional methods and can quantify the femtograms※ of protein in only a few minutes.
This technology is expected to apply on the wide range of fields including medical and food areas. For example, it may accelerate and simplify screening process in the pharmaceutical development and diagnosis of individual patient in the personalized medicine.
