Emerging Pathogens and an Emerging Market

A news item in Science reports on the rise of biotech in Hong Kong, which in recent years has dedicated hundreds of millions of dollars to attract translational scientists and research centers to the area. In an anecdote of an up-and-coming biotech company, Science profiles Albert Cheung-Hoi Yu and his company, Hai Kang Life, which "rolled out a novel chip that binds target DNA strands and coats them with nanoparticles for identification." The chip is currently being tested for pathogen detection. Yu is also important in the broader picture: "When he's not in the lab, Yu ... promotes biotech here as inaugural chair of the Hong Kong Biotechnology Organization," the article notes.
