Researchers at Pennsylvania State University have demonstrated a new technique for nano-manufacturing that could make it significantly easier to create high-precision components for nanoscale electronics, sensing devices and the like.
Known as microdisplacement printing, the new technique is based on a widely used patterning method known as microcontact printing--a simple way of fabricating chemical patterns that does not require clean rooms and other kinds of special and expensive environments.
Both methods involve "inking" a patterned rubber-like stamp with a solution of molecules, then applying the inked stamp to a surface. "But the new microdisplacement technique gives us more control over the precision with which the patterns are placed and retained, and also allows us to use a wider range of molecules," says principal investigator Paul Weiss.
Weiss and his colleagues were funded in part by the National Science Foundation, and will describe their new technique in the 14 September issue of the journal Nano Letters.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
