SEM images showing the dependence of the particle coverage on the footprint of the droplet, using a constant total volume. Results of manual spotting (1 μL) the sample onto a a SiO2 - PDDA surface (CA < 20°), b Si-PDDA (CA = 50°), and c Si-FDTS-PDDA (CA = 85°). Results of microspotting a series of droplets (468 nL/deposit) on the Si-FDTS-PDDA (CA = 85°) surface are also shown, comparing the footprint and particle coverage on a surface held d at room temperature and e at 50 °C on a hotplate. f A plot showing the relationship between particle coverage with the footprint of the droplet
