From: Direct microcontact printing of oligonucleotides for biochip applications
Comparison between μCP deposition and contact deposition using metal pins. Evolution of the fluorescence intensity in arbitrary units as a function of the concentration of the solution containing the probe molecules. 60 μm diameter spots of 20-mer oligonucleotides from HSP12, were deposited using a commercial Spotter (VersArray ChipWriter Pro, BIO-RAD) and then hybridized with the complementary labeled molecules. Disks and square of the same dimension were printed by μCP and treated exactly in the same conditions.
