A robot that reads bacteria by touch, without staining or chemical labels

Fast identification of bacteria is important in health care, food safety, environmental monitoring and infection control. One of the most common first steps is gram classification, which separates bacteria into gram-positive and gram-negative groups. This information can help guide early treatment decisions and safety responses. However, conventional Gram staining requires several chemical steps, trained personnel and manual interpretation.
