Our team has developed a number of massively parallel, cantilever-free scanning probe lithography instruments that can be used for large-area, low-cost, arbitrary surface patterning. These tools are the first of their kind and enable one to study the chemical consequences of materials miniaturization, opening avenues for nanocombinatorial studies in fields such as cell biology and heterogeneous catalysis, not possible with other methodologies..
POLYMER PEN LITHOGRAHY (PPL) ENABLED M series
Polymer-Pen Lithography (PPL), combines the advantages of DPN with micro-contact printing while eliminating many of the limitations of the two techniques. A typical PPL array is made from an elastomer, which is cured in a Si mold fabricated by photolithography and then mounted on a flat, transparent substrate (glass or quartz). The array is then coated with an ink of interest and used in a TERA-fab instrument for large area nanopatterning. A typical array is 2.0 x 2.0 inches, and is comprised of as many as 2.80 million pens.
In a PPL experiment, tip-substrate contact force is used to control feature size, thus allowing rapid generation of micro and nanoscale features by varying tip compression. By using the Si master as an inkwell, each of the tips within the array can be coated with different inks allowing for multiplexing.
