    A convenient photochemical method to immobilize enzymes (1984)
    New York : Wiley-Blackwell

    Notes: A method to immobilize enzymes photochemically with use of photocrosslinkable poly(vinylalcohol) bearing stilbazolium groups is described. Irradiation of a film of the photosensitive polymer containing enzyme gave water-insoluble, cellophane-like transparent film demonstrating high enzyme activity. The dissolution of enzymes from the film was dependent upon the molecular weight of the proteins and the content of the photocrosslinking unit. It was found that various enzymes are sufficiently entrapped in the photocrosslinked polymer matrix when the content of the photosensitive group is more than about 1.0 mol%.

    Immobilization of enzymes with use of photosensitive polymers having the stilbazolium group (1980)

    Notes: Reaction of the homopolymer of 2-chloroethyl vinyl ether and the copolymer of N-vinylpyrrolidone with stilbazole produced photosensitive polymers. The photocrosslinking mechanism is discussed. Irradiation of a film of the water-soluble photosensitive polymer yielded insolubilized material in which the enzymes were entrapped. The activity of entrapped invertase, glucoamylase, and catalase was 30, 60, and 35%, respectively.

    Notes: The reaction of PVA with 2,2-dialkoxyethoxystyrylpyridinium or quinolinium salts is described. The resultant water-soluble polymers, which contain small amounts of the styrylpyridinium- or quinolinium group, exhibited high photosensitivity. Among the polymers prepared PVA-bearing 4-oxystyrylquinolinium group was photoinsolubilized with visible light that corresponded to an argon laser.

    Preparation and characteristics of photocross-linkable poly(vinyl alcohol) (1982)

    Notes: The reaction of poly(vinyl alcohol) with styrylpyridinium and quinolinium salts which contain formyl group produced water-soluble photosensitive polymers. The sensitivity was high, although the content of the styryl groups was extraordinarily low. Spectroscopical studies revealed that the high sensitivity is due to the aggregation of photofunctional group in the polymer matrix which leads to cyclodimerization on exposure to ultraviolet (UV) light.
