    摘要： The present invention is a method of producing porous beads, which comprises the steps of providing a first liquid phase comprising a bead matrix material and essentially edgy templating particle(s), said particle(s) being treated with a surface modifying agent; providing a second liquid phase which is immiscible with the first liquid phase; contacting the first phase and the second phase under conditions resulting in an emulsion of droplets comprised of the first liquid phase dispersed in the continuous second liquid phase; transforming the droplets to mesoporous beads by solidification of the liquid; and removing the templating particle(s) from the beads without causing any essential change of the surrounding bead, whereby hierarchical networks of pores are provided in the beads.

    摘要： The present invention relates to a microcarrier onto the surface of which a cationic compound has been immobilised via a guanidine group. The microcarrier is capable of attachment of cells, e.g. via charge-based interaction, and is advantageously used as a support in the culture of cells. Said compound may comprise one or two amino acids, such as arginine (Arg) or a dipeptide. The invention also relates to a method of preparing a polycationic microcarrier, which method comprises to immobilise a compound that comprises at least one guanidine group to an epoxide-activated substrate.
