Molecular inks

In order to improve the stamping resolution of the elasomeric stamp, there have been recent improvements in both the stamp and molecular inks e.g., alkylthiols, silanes). In particular, traditional PDMS exhibits a relatively high elasticity that limits possible relief linewidths on the other hand, small molecular weight inks exhibit diffusion during patterning. Hence, the following complementary strategies have been employed ...

Molecules are transferred by diffusion from the interface to a substrate and a water meniscus is formed by capillary condensation ii. ink from the reservoir is... 

SAMs [297]. Alkanethiols can play a critical role in SPL on SAMs. Alkanethiols are often called molecular inks, the idea of which has been already recognized as reactive chemical ink of microcontact printing (pCP) [9j. 

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...
