CombiMatrix and Toppan Printing to Develop and Market Microarrays

CombiMatrix said today that it has formed a strategic alliance with Toppan Printing to develop and manufacture microarrays that use electrochemical detection.


Toppan of Tokyo, Japan, will pay CombiMatrix, a subsidiary of Acacia Research, an upfront fee of $1 million as well as additional development and milestone fees. Toppan will manufacture microarrays for CombiMatrix and its partners and share revenues and royalties on these.


The two companies plan to co-develop semiconductor microarrays for applications in research and diagnostics. Unlike microarrays that CombiMatrix has developed in collaboration with Roche, which use optical detection, these arrays will rely on electrochemical detection.


CombiMatrix said it has already tested this technology in small prototype instruments and assays for biological and chemical defense applications.
