Abstract

This article reviews commercially available instrumentation for inkjet printing of polymer micro‐arrays for combinatorial materials research, and requirements thereof. These include a print head positioning accuracy better than 10 μm and a minimum drop volume of 100 pL. Commercially available instruments that fulfill these requirements can be divided into two categories, depending on whether they receive ink from a reservoir (dispense mode) or through fluid aspiration (pipette mode). Instruments belonging to the first category are restricted to the preparation of polymer blend micro‐arrays. These consist of a few substances mixed in various ratios. The other instruments can be used for the preparation of both micro‐arrays of large numbers of different pure polymer compounds and polymer blend micro‐arrays. Moreover, ways to mix compounds are discussed.
