    摘要： The present invention provides a method for making porous bodies of magnetic glass and/or crystal-containing materials having magnetic crystals incorporated therein with dimensions less than about 1000A. Preferably, the crystals have dimensions less than 500A such that the porous bodies demonstrate essential superparamagnetic behavior. The method involves preparing a body which, upon heat treatment, will separate into at least two vitreous phases and at least one crystal phase. One of the vitreous phases is etched away leaving a structure remaining which contains said magnetic crystals. When present as fine particles, the porous magnetic bodies are especially suitable for use in biological assays.
