Fig. 3From: Silica nanoparticles with encapsulated DNA (SPED) to trace the spread of pathogens in healthcareResults of the ‘Explorative experiments’. Explorative experiment 1: Transmission of SPED deployed to subgluteal human skin to inanimate objects such as the toilet seat or the door handle through a standardized toilet sequence; Explorative experiment 2: Transmission of SPED deployed on Participant-A’s subgluteal skin to Participant-B’s subgluteal region through successive use of the same toilet. The concentrations of SPED as measured by qPCR are displayed on a logarithmic scale. The baseline corresponds to the background concentration, meaning any positive value in the diagram corresponds to a signal above the baseline samples taken before SPED deployment.
