The invention relates to an oxynitride glass fiber for composite products which has a surface cladding formed from a composition containing a silane coupling agent. This fiber is excellent in strength, elastic modulus, adhesion and wetting property with respect to matrix resin. A composite product comprising the above clad oxynitride glass fiber and a thermaplastic or thermosetting resin matrix is also disclosed. This composite is excellent in strength, elastic modulus, toughness and interlaminar shear resistance.

An oxynitride glass, a process for preparing same and a fiber thereof, in the glass which has Si--M.sub.1 --M.sub.2 --O--N system and contains SiO.sub.2, Si.sub.3 N.sub.4 and M.sub.1 O in amounts which, as mole %, satisfy the following equations (a) and (b):

Oxynitride glass and the fiber thereof

Peptide-containing compounds such as enzymes, antibodies and antigens are immobilized on metal hydroxy gels formed by hydrolysis of metal alkoxides in an aqueous solvent while evaporating off the solvent. Preferably, hydrogen fluoride is present in the solvent during hydrolysis to provide a fluoride-substituted metal hydroxy gel. Water containing lower alcohol is a preferred solvent. The gel is treated with a coupling agent and a peptide-containing compound is chemically bonded to the gel.
