Mechanism of Liquid Transfer

The mechanism of liquid transfer from the reservoir to the surface through the aperture is rather complex. It involves both a flow of the liquid in the nanochannel and the spreading of the liquid on the

The mechanism of liquid transfer from a tip to the surface is rather complex and involves a large number of parameters, which are related to liquid properties, tip and surface geometrical, or chemical aspects or to the deposition procedure itself. In the following sections the influence of these parameters is reviewed. 

The time of contact between the tip and the surface is an interesting control parameter since it allows changing the size of the spots for a given system. It can also give insights into the mechanism of liquid transfer, a better understanding of which is crucial to optimize the technique.
