Fig. 5From: Silica nanoparticles with encapsulated DNA (SPED) to trace the spread of pathogens in healthcareResults of the ‘Mobile device experiment’. Quantitative results of experiment mimicking a mobile device use scenario. The concentrations of SPED as measured by qPCR from individual swab sites 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 deploymentBack to article page
