Example text

One of the first investigations into the flow of conducting liquid through a charged tube with a counterelectrode some distance away was conducted by Zeleny [17]. A great deal of these experiments used aqueous electrolyte solutions with high electrical conductivity and low viscosity. The addition of a charge to this solution caused it to form a fine spray of charged droplets that were attracted to the counterelectrode. These droplets quickly evaporated in the air; this process was later called electrospraying.

Soft lithography techniques are not subject to the limitations set by optical diffraction, as discussed earlier (the edge definition is set by van der Waals interactions and the properties of the materials used) [4]. They offer procedurally simple, less expensive alternatives to the production of nanoscaled structures through photolithography. 4 Dip Pen Lithography Dip pen lithography is a type of scanning probe lithography. In this lithographic technique, the tip of an atomic force microscope (AFM) is used to create micro- and nanoscaled structures by depositing material onto a substrate.

This approach is distinct from the mechanical transfer of micropatterns of a die into a polymer, as well as conventional photolithography. The limitations of the former are that the polymer has to be a thermally stable thermoplastic material and the surface chemistry cannot be modified. In the latter case, the surface and bulk chemistry are difficult to modify simultaneously while applying a specific pattern. 3 MICRO/NANOMACHINING OF ‘‘SOFT’’ POLYMERIC BIOMATERIALS Polymers have enjoyed widespread use in many biomedical applications, ranging from contact lenses, intraocular lenses, dental implants, vascular grafts, artificial hearts, breast implants, biodegradable sutures, pacemakers, artificial skin, and joint replacements.
