ABSTRACT:
Arrays of electro-mechanical dispensers are used to form extremely small drops of fluid and locate them precisely on substrate surfaces in miniature arrays. The printed arrays may consist of DNA, immunoassay reagents or the like. A positioning support such as an X-Y table moves the dispensing devices and substrate surfaces relative to each other to locate the drops on the substrates in predetermined patterns. Arrays of probes as dense as one thousand per square centimeter with center-to-center spacing as small as twenty-five micrometers are formed.
