California Institute of Technology News
Smart petri dish analyzes cell growth
PASADENA, Calif. — Built from a smartphone, a commercially available cell phone image sensor and some Lego blocks, ePetri isn’t like other petri dishes. The compact, lens-free microscopy imaging platform can track cell cultures and bacteria as they incubate. Petri dishes have been used primarily to grow cells and to help identify bacteria at the center of infections such as tuberculosis. Their conventional use with cultures requires cells to be placed in an incubator. As a sample grows inside the...
Smart Petri Dish Provides Lensless Imaging
PASADENA, Calif., Oct. 14, 2011 — Using a smartphone and some Lego blocks, engineers at California Institute of Technology have created a new way to analyze cell cultures on the fly. Because the phone’s imaging chip is used as a quasi petri dish, the Caltech team has...
