doi: 10.1021/acs.langmuir.3c03709
Figure Lengend Snippet: Photos showing the shape of 6 μL water drops and images using laser scanning confocal microscopy of a water drop labeled with fluorescent dye (1 mg L –1 ) (cyan color) resting on the superhydrophobic surfaces prepared with (a) one coating cycle, (b) two coating cycles, (c) three coating cycles, (d) four coating cycles, and (e) five coating cycles. The reflection from the substrate-coating interface is shown in red.
Article Snippet: The instrument utilized for imaging and force measurements is specially designed and consists of an inverted LSCM coupled with a JPK NanoWizard AFM (JPK Instruments AG)., , For surfaces showing attractive forces exceeding 15 μm, the force range exceeded the range of the internal AFM piezo scanner.
Techniques: Confocal Microscopy, Labeling
