Our history traces back to 2014, when a research team composed of postdoctoral fellows and scientists from multiple prestigious universities and institutions in the United States, including two postdoctoral fellows from the Lawrence Berkeley National Laboratory, a postdoctoral fellow from the California Department of Public Health, a professor from McMaster University, as well as Dr. Joshua Robinson and Academician Hongjie Dai from the U.S. National Academy of Sciences, was established in Joinn Innovation Park, located in the heart of Silicon Valley, California, USA.In November of same year, we had research cooperation with Nirmidas and StartX (Stanford’s Accelerator) on Personal and Portable Health Diagnostic Testing. In the following year, our first colloidal analyzer passed the test from DCN, the authorized device test organization in the US.
