Abstract

In this paper, the implementation of an automated real-time spotting system is discussed. It is intended for high density, high yield microarray fabrication to facilitate diagnostic and research effort in genomics and proteomics. The method is based on a self-sensing, fully automated aspiring/dispensing pin. System performance is evaluated by several batch runs with de-ionized water solution of 0.3% fluorescent Cy-3 dye which has similar physical properties to the deoxyribonucleic acid (DNA) probe materials. Experiment results show that this system is capable of fast and robust DNA/protein microarray fabrication in high volume while keeping spot size as small as 60um consistently. Based on the laser scanned images and experimental data of the spotted microarrays, it is also verified that this system can recognize and prevent the formation of abnormal spots. ©2007 IEEE.
