METHOD TO IMPROVE QUALITY OF MICROARRAYS BY CONTROLLING EVAPORATION

Methods and compositions described here minimize loss due to evaporation during the process of preparing gel-element microarrays; maintain uniform gel density; minimize irregular spontaneous polymerization; and provide conditions to obtain reproducible and consistent gel-array elements. The materials and methods described herein present techniques for restoring the original composition of the droplets dispensed on the microarray substrates prior to and during the step of ultraviolet light polymerization.
