Short summary
Dry and wet aerosol deposition modes are commonly used to collect particles on a solid substrate for experiments. We demonstrate, using single-particle microscopy and bulk methods, how the substrate-deposited particles with two components can yield the same core–shell morphology but different shell thicknesses depending on the deposition method. Thus we strongly advise future works to use wet deposition when possible to obtain accurate assessment of the single-particle organic volume fraction.
