<p>The method of making borosilicate glass with a surface having reactive SiOH groups on it includes preparing a borosilicate glass melt and dissolving at least 30 mMol per liter of water in the borosilicate glass melt. The borosilicate glass contains from 70 to 87 percent by weight, SiO<SUB>2</SUB>; from 7 to 15 percent by weight, B<SUB>2</SUB>O<SUB>3</SUB>; from 0 to 8 percent by weight, Al<SUB>2</SUB>O<SUB>3</SUB>; from 0 to 8 percent by weight, Na<SUB>2</SUB>O and from 0 to 8 percent by weight of K<SUB>2</SUB>O. The borosilicate glass with the easily modified reactive surface can be used as a substrate for chemically covalent immobilization of reactive substances. This substrate can be used to make a biochemical chip, such as a DNA or gene chip, or dirt-proof window glass.</p> |
