Porous glass fibers with immobilized biochemically active material

Biochemically active material is immobilized on porous silica-rich glass fibers having a diameter of about 3 to 150 microns, a length of about 0.03 inch to continuous fiber length, a mean pore diameter in the range of about 10 to 3000 angstroms, a pore volume of about 0.5 to 1.5 cc/gm and a surface...

Beschreibung
Zusammenfassung:	Biochemically active material is immobilized on porous silica-rich glass fibers having a diameter of about 3 to 150 microns, a length of about 0.03 inch to continuous fiber length, a mean pore diameter in the range of about 10 to 3000 angstroms, a pore volume of about 0.5 to 1.5 cc/gm and a surface area of about 10 to 600 m2/gm. The porous glass fibers are preferably formed from a composition containing greater than 35 up to 60 weight percent B2O3, about 1 to 10 weight percent alkali metal oxides, about 30 to 65 weight percent SiO2, up to about 5 weight percent ZrO2, and up to about 4 weight percent Al2O3. Fibers having the composition are heated to cause phase separation into a boron-rich phase and a silica-rich phase, and are then treated by water and acid leaching to produce the porous glass fibers. A biochemically active material is attached to the fibers by absorption or by covalent bonding with a linking agent.
