Fig. 1From: Silica nanoparticles with encapsulated DNA (SPED) to trace the spread of pathogens in healthcareFloor plan of the ‘Patient experiment’ ward with room assignments. The floorplan shows the study ward three times (once for each study run) and the localisation of the two-bed patient room, shared restroom, nurses’ and doctor’s office in the study ward. In Run-1 the doctor’s office was situated on another floor and does therefore not appear in the floor plan. The plus signs indicate rooms with one or more positive SPED swabbing results at 8-h follow-up. Detailed swabbing sites s. Table 1. SPED silica nanoparticles with encapsulated DNABack to article page
