Abstract:
A method for forming a microarray of biological materials on a substrate, comprising:providing a plurality of sample reservoirs which contain samples; providing a sampling device; positioning the sampling device adjacent to the sample reservoirs; using the sampling device to draw a selected sample into the sampling device from the sample reservoirs; delivering the selected sample to an ejector through a conduit; providing a substrate; positioning the ejector adjacent to the substrate using a transport mechanism for moving both the substrate-holding support and the ejector relative toward each other; delivering the sample from the ejector to a predetermined location on the substrate; repeating the above steps after cleaning the sampling device the conduit and the ejector such that multiple samples are delivered to the substrate at predetermined locations to form a microarray of biological materials.
