Single-cell fluorescence intensity of E. coli BW25113 expressing mScarlet red fluorescent protein under the control of the tolC promoter upon exposure to copper, NsARC and stainless steel under (A) UV light, (B) visible light, (C) ambient light and (D) dark. The violin plots show the distribution of the single-cell fluorescence within the cell population. The bar in the box depicts the median and the box shows the 25% and 75% quartiles
