MICROSPHERES MAGNETISABLES A BASE DE POLYSILOXANE, LEUR PROCEDE DE PREPARATION ET LEUR APPLICATION EN BIOLOGIE |
摘要 |
Magnetisable microspheres, as they are or in aqueous dispersions, consisting of a matrix of at least one organopolysiloxane optionally bearing Si-vinyl groups or reactive and/or ionogenic units and, encapsulated in said matrix, magnetisable particles less than 300 ANGSTROM in size. …<??>They are prepared by homogenisation of a solution of the said organopolysiloxane and a magnetic fluid in the presence of water and a surfactant, removal of the solvent of the organopolysiloxane and of the carrier liquid of the magnetic fluid and at least partial removal of the water. …<??>They may be used in biology. |
