The accurate placement of extremely small volumes of fluids can enable both multistep in situ synthesis on a substrate surface and deposition of {HEAD ~ an intact molecule} within {TAIL ~ an extraordinarily small zone} without the need to mask, pre activate surface sites, or otherwise modify a predetermined region of a surface
