Fig. 6From: Real-time monitoring of bacterial biofilms metabolic activity by a redox-reactive nanosensors arrayBacterial biofilm was monitored over three cycles of glucose consumption; untreated biofilm (blue), short-term exposure to ampicillin (red), and long-term exposure (black). The long-term treatment slows the metabolic cycle and, in the end, the glucose signal shows ~ 40% remaining of the original amount. At the beginning of each cycle, the glucose medium contains 1.8 mM glucose. Inset: trend lines of the three glucose-consumption cyclesBack to article page
