Patent number: 6358531Abstract: A method is provided for preparing shells, concentric shells or porous, homogenous gels from alkali borate glass particles at low temperatures (i.e. room temperature or less than above 100° C.). The alkali borate glass particles contain one or more cations such as aluminum which react with an aqueous solution containing an anion such as hydroxide to form an aqueous insoluble material having a solubility limit of less than about 0.01 wt. percent. The resulting shells or gels may be used in many different applications such as a filler in resins, as filters, precursors for nano-sized powders, as thin surface films or catalyst support media. The resulting shells or gels may also have a chemotherapeutic drug added thereto, following which the resulting product is administered to a mammal and the insoluble material is dissolved form the product in vivo through administration of chelating agent.Type: GrantFiled: February 1, 1999Date of Patent: March 19, 2002Assignee: The Curators of the University of MissouriInventors: Delbert E.
