Disposable Clorimetric Array on a Petri Dish

Caption

A colorimetric sensor array is placed in an Petri dish for culturing bacteria and scanned with an ordinary flatbed photo scanner kept inside a lab incubator. The dots change color as they react with gases the bacteria produce, identifying specific strains through their aromatic "fingerprints."
