Abstract: Methods for producing glass substrates having scribed edges with straight and smooth ends substantially free of edge protrusions, and microarray glass substrates produced thereby, are provided. In certain embodiments, at least one scribe line is scribed in glass using reduced laser power at the beginning and end of each scribe line relative to the laser power used to scribe the remaining portions of each respective scribe line. In other embodiments, a heat absorbing laser element is positioned adjacent the beginning and end of each scribe line. In all embodiments, the scribed glass is singulated to produce a plurality of scribed glass pieces, each having straight and smooth ends substantially free of edge protrusions. The scribed glass can be used as substrates for biopolymeric microarrays. Also provided are biopolymeric microarrays produced from the subject methods and kits which include the subject microarrays, as well as methods for using the same.
