1. DNA samples can be covalently
attached onto a treated glass
surface.
2.
glass is a durable material that sustains high temperatures and
washes of high ionic strength.
3. it
is non-porous so the hybridization volume can be kept to a
minimum, thus enhancing the kinetics of
annealing probes to
targets.
4. as a consequence of its low fluorescence, it does
not
significantly contribute to background’noise’.
