Organo-silane coated substrates for DNA purification

► Thermally grown silicon oxide, silicon oxide by PECVD and Pyrex were silanized. ► DNA capture and elution by AEEA- or APTES-treated surfaces were evaluated. ► AEEA-surface releases more DNA than APTES. ► APTES-treated PECVD or Pyrex is the best for DNA purification. ► Possible use to purify DNA from blood or short DNA fragments from longer ones.
