From: Rapid in situ assessment of Cu-ion mediated effects and antibacterial efficacy of copper surfaces
Correlation between Cu biosensor induction by copper surfaces and Cu content or dissolution of the surface material. Linear correlation between raw and corrected bioluminescence induction of the Cu biosensor on copper and copper alloy surfaces and Cu content of those surfaces (a) or copper release from these surfaces (b) after 60 min. Arrows indicate the difference between raw and corrected bioluminescence induction. All experiments were performed in LB medium in three replicates. (c) Copper content and release of Cu from the different copper surfaces in LB medium. Mean and standard deviation of three replicates are shown.
