The researchers are able to quickly design and create custom engineered and functionalized surfaces using the Dip Pen Nanolithography (DPN) technique to transfer nanoliter or smaller amounts over a large, environmentally controlled area.
To begin, the system provides arrays of pens to write simultaneously over areas as large as 40mm x 40mm. The pens will deliver a spot size over a broad dynamic range of 50nm up to 10s of microns. Using NanoInk’s Inkwell devices, multiple materials may be deposited in one step.
The NLP 2000 will write onto a diverse range of substrates including Petri dishes and coverslips. The use of a standard optical microscope slide makes the creation of the arrays easily portable to various standard detection systems. The large format and work area also permit the use of a variety of tissue culture plastic dishes.
This new DPN-based instrument is designed to serve the growing need for large area deposition of nanoarrays and is the first capable of fabrication of sub micron features over large areas.
