Test Structure (image) DOE/Sandia National Laboratories Caption This tiny test structure was fabricated from the same photo-crosslinkable PDMS material which has been implanted into rats as part of the MD Anderson Cancer Center-University of New Mexico-Sandia collaboration. The test structure helps researchers characterize the performance of their microprojection lithography system.
