From: Adsorption of a water-soluble molecular rotor fluorescent probe on hydrophobic surfaces

Adsorption of 4-daspi on hydrophobic glass decreases with glycerol concentration (a) Schematic representation of how reduction of energetically unfavourable contacts for molecules close to the glass-solution interface may drive the adsorption of 4-daspi to hydrophobic glass. (b) Adsorption of 4-daspi to the hydrophobic surface (\(\sigma _{\textrm{O}}\)) as deduced from confocal intensity z-scans, corrected for artefacts as described in the text. Error bars 1 s.d. for data collected at \(z_{\hbox {F}}=5,7,10,20,30\) \(\upmu\)m. The black dashed line is just to guide the eye.
