the molecules. As seen in the schematic representation, the substrate is coated with
a protein to be patterned and is mounted on a xyz translation stage. The stage is then
moved in a predetermined pattern and speed. Exposure to focused UV laser causes
denaturation or removal of the protein and a desired pattern of functional protein is
formed [68] (Figure 5.13).
5.3.4.2 Inkjet Printing
Inkjet printing is a form of noncontact patterning technique that is based on the work-
ing principle of a desktop printer, where numerical data from a computer are trans-
lated to printing patterns on sub ...
