    摘要: Provided herein are biocompatible scaffolds and methods of preparing such bioscaffolds. The methods provide a superior high surface area, interconnected nanomacroporous bioactive glass scaffold, by combining a sol-gel process and polymer sponge replication methods. The formation of a uniformly nanoporous and interconnected macroporous bioscaffold is demonstrated using a starting material comprising a 70 mol % SiO2—30 mol % CaO glass composition as an example. The bioscaffold includes a series of open, interconnected macropores with size from 300 to 600 μm, as desired for tissue ingrowth and vascularization. At the same time, coexisting nanopores provide high-specific surface area (>150 m2/g), which is needed for enhancing the structure's degradation rate. These bioscaffolds hold promise for applications in hard tissue engineering.

    摘要: Some embodiments in the present disclosure generally relate to fluorescent structures such as fluorescent glass, fluorescent substrates, and/or light emitting devices, which can include a gradient of fluorescent molecules across the structure, substrate, and/or light emitting device. In some embodiments, the fluorescent glass, fluorescent substrates, and/or light emitting devices can be porous and include at least one fluorescent molecule within the one or more pore. In some embodiments, this can allow for the creation of a gradient fluorescent material throughout the material.

    摘要: A process for making foamed glasses and ceramics from sol-gels is disclosed. The method includes preparing a mixture of reactants capable of forming a sol-gel with addition of a catalyst to control the condensation stage followed by foaming using vigorous agitation in the presence of surfactants. The gelled bodies are aged, dried, and thermally stabilized to obtain a consolidated macroporous material. The resulting structure comprises a three-dimensional network of spherical open pores that are thoroughly interconnected. The process may involve sol-gel systems using a mixture of metal alkoxides, and may produce glasses in unary systems (SiO2), binary systems (70% mol SiO2-30% mol CaO), and ternary systems (60% mol SiO2, 36% mol CaO, 4% mol P2O5). The macro-porous material has pores in the 10-500 μm range and has potential for use as matrix in tissue engineering, in bone repair, and in organ regeneration.
