Application of porous microspheres prepared by SPG (Shirasu porous glass) emulsification as immobilizing carriers of glucoamylase (GluA)

Preparation of highly monodisperse W/O emulsions with hydrophobically modified SPG membranes

“…Moreover, W/O emulsions were applied to produce multiple emulsions [4], microcapsules for capsulizing medicines, and microspheres for packing gel permeation chromatograph (GPC) and high performance liquid chromatography (HPLC) columns [5,6], immobilizing enzymes [7] and loading protein drugs [8]. The mean size and size distribution of emulsions are of especial significance for fabrications of all these "hightech" products.…”

Effects of organic solvents on ultrafiltration polyamide membranes for the preparation of oil-in-water emulsions

“…These applications include preparation of core particles for toner application [11], preparation of liposome [12] spacers for liquid crystal displays [13] preparation of uniform silica hydrogel particles [14], and synthesis of monodisperse polymer microspheres. Such polymer spheres have been used as packings for HPLC columns [13], as immobilizing carriers of enzyme [15], and as biodegradable drug delivery systems [16].…”

Compromise between dominant polymerization mechanisms in preparation of polymer microspheres

“…Due to these features, polymer microspheres have found use in various ÿelds, such as the traditional industries of paint, ink, and paper, as well as ÿne applications in recent years, e.g. carriers for enzymes (Hayashi and Ikada, 1990;Omi et al, 1997;Tang et al, 1999;Brahim et al, 2002), separation media for proteins (Ugelstad et al, 1992;Okubo and Hatorri, 1993;Inomata et al, 1995;Feng et al, 1998;Li et al, 2000), DNAs (Uhlen, 1989;Kawaguchi et al, 1989) and cells (Ugelstad et al, 1993), carriers for protein refolding (Shimizu et al, • Immunoassay microspheres (Dolitzky et al, 1994), on which antibodies or antigens are immobilized, are used to detect or separate their complementary antigens or antibodies. These microspheres should be spherical with smooth surfaces and small enough to give large speciÿc areas.…”
