Setup of the ‘Mobile device experiment’. Scenarios plot: (1) Researcher deploys SPED on neck (A. carotis), chest (Erb’s point), and wrist (A. radialis) of Patient-A′; (2) Doctor-A listens to heart sounds and takes radial pulse of Patient-A′; (3) Phone rings, Doctor-A takes the call for 30 s, then leaves the experiment scene; (4) Phone rings again, Doctor-B takes the call for 30 s; and (5) listens to heart sounds and takes radial pulse of Patient-B′. Star symbols indicate SPED swabbing sites. SPED silica nanoparticles with encapsulated DNA.
