Abstract: In one aspect, there is provided a method for preparing a biocompatible coated substrate. The method generally includes: depositing nucleation amorphous calcium phosphate sites on at least a portion of an outer surface of a substrate by: exposing at least the portion of the outer surface to a mixture having a favorable Ca/P molar ratio, and irradiating with microwave energy; and, stabilizing the deposited nucleation amorphous calcium phosphate sites on the portion of the outer surface. In another aspect, there is provided herein a method for preparing a biocompatible coated substrate.

Abstract: Compositions of, methods of making, and methods of using alkaline earth phosphate bone cements are disclosed. A bone cement composition includes a powder comprising a basic source of calcium, magnesium, or strontium, a setting solution comprising H3PO4 and a buffer, and a biocompatible polymer that is incorporated into the setting solution. The powder is mixed with the setting solution to form a bone cement paste that either (a) sets into a hardened mass, or (b) is irradiated with electromagnetic radiation to form dry powders, the dry powders then being mixed with a second setting solution to form a radiation-assisted bone cement paste that sets into a hardened mass.
