Wetting Conical Tip, Nanoneedle and Carbon Nanotube at Liquid-Air Interfaces

2 Wetting Conical Tip, Nanoneedle and Carbon Nanotube at Liquid-Air Interfaces 

Because the study of liquid interfaces by scanning probe microscopy [SPM] requires using specific tips usually milled with FIB or else using high-aspect-ratio tips grown at the apex, micro- and nanofluidics using SPM has started only recently. When a standard pyramidal tip is put in contact with a liquid surface, a large meniscus is created and is detrimental to any measurement. Noncontact
