Microcontact printing allows us to mark specific areas of a surface with chiral molecules similar to a self-assembled monolayer, a SAM. These areas can be visualised as zones of a certain handedness. Imagine that you have huge patterned areas, separated but on a single support. They are surrounded by an environment that repels water like wax and they are hydrophilic points which mean they attract water and other polar chemicals. Each of the points is designed to catch one type of molecule specifically or in our story different coloured gloves. The microcontact printing technique is the procedure that enables you to create all kinds of patterns of enantiomers with varied designs. Resolve employed microcontact printing to pattern surfaces with chiral molecules in order to promote the growth of specific enantiomers. We manage to create unique surface layers with different shapes that have varying ability to make crystals grow. This kind of localised crystallisation is useful for the purification of enantiomers.
