Caltech Engineers Build Smart Petri Dish


Electrical engineering graduate student Guoan Zheng, working with Professor Changhuei Yang and Professor Michael Elowitz, has built a platform for a "smart" petri dish, dubbed ePetri. "Our ePetri dish is a compact, small, lens-free microscopy imaging platform. We can directly track the cell culture or bacteria culture within the incubator," explains Zheng, "the data from the ePetri dish automatically transfers to a computer outside the incubator by a cable connection... this technology can significantly streamline and improve cell culture experiments by cutting down on human labor and contamination risks."
