Top down imaging is used to extract the contact angle, θ, of drops on surfaces greatly relaxing the requirements and limits demanded by side imaging. The method is compared between two standard lateral measurement techniques (the tangent method and the height/diameter method) for the hydrophilic contact angle of a droplet of water (20 drops of 2 l each) on borosilicate slide: θ = (52 ± 7)° and (52 ± 6)°, respectively, and (53 ± 8)°, for the proposed method, agreeing within experimental error. This technique can be applied on multiple contact angle measurements, depression, between electronic components and on concave surfaces. The top down method has the potential to revolutionize diagnostics by making contact angle measurements ubiquitous and accessible to low cost imaging.

The dynamic surface wetting kinetics of sessile water and ethylene glycol droplets deposited on ink-jet papers was studied. The hydrodynamic and molecular-kinetic models were used for data analysis and the results were compared with each other. Hoffman-Tanner plots gave good linear fits with experimental data, but only the low velocity linear data fit correlated well with experimentally determined pseudo-equilibrium contact angles. The molecular-kinetic model gave a good non-linear fit with experimental data and produced physically meaningful values for the molecular parameters. A high rate wetting phase was found for some liquid-paper sample systems, which was correlated to capillary flow in 'micro-crack' surface structures. Deviation in low rate wetting behaviour from the hydrodynamic and molecular-kinetic models cannot solely be explained by surface structure and roughness. Consequently, it can be assumed that surface chemistry has a significant effect on wetting dynamics.
