Rather than having to use a mold for nanocontact printing, one may also directly write features onto an appropriate substrate using a molecular ink, via the ultra-fine tip of an atomic force microscope (Figure 4.75). The use of such a nanofountain pen is known as dip-pen nanolithography (DPN), first demonstrated by Mirkin and... 

Essentially two implementation strategies of this concept were developed and named "nanofountain pen" (NFP). "In both cases, microchannels with typical sections of 300-500 nm by 2-10 pm were fabricated in the cantilever and its support using...
