This Small Business Innovation Research Phase I project seeks to develop nanomanufacturing methods for producing metal-oxide composites for biomedical implants. Homogeneous, mixed metal-oxide composites are extremely difficult to prepare by existing processes, and although of great utility, mixed-oxides have found limited applications in markets outside of biomedicine due to cost constraints. We have obtained preliminary data demonstrating a new, highly-efficient and low-cost approach to the manufacture of these materials which uses precise flow and mixing control to assemble the individual components of the mixed-oxides at the nanoscale. The process utilizes inexpensive nanomaterial components (e.g., colloids) that are readily available. The process produces complex "core-shell" nanomaterials that are then further processed to produce a mixed-oxide with greatly increased functionality. We anticipate that these materials will exhibit the commercially important properties of radiopacity (aiding diagnostic capabilities) and bioactivity (for better implant integration).The broader impact/commercial potential of this project is to provide bio-medical implants that better integrate into the human body, speed the healing process, improve durability, extend the use-life and aid diagnosis. This will ultimately reduce the rate of revision surgery and improve patient outcomes. The process has many significant advantages over existing methods of manufacturing, including increased functionality, dramatically improved product yield (leading to lower cost), and significantly improved performance. This process provides a significant manufacturing cost advantage over existing materials and can be further leveraged to expand market opportunities into adjacent segments where cost constraints have limited the adoption of advanced composites.

该小型企业创新研究第一阶段项目旨在开发纳米制造方法，用于生产生物医学植入物用金属氧化物复合材料。均质的混合金属氧化物复合材料极难通过现有工艺制备，尽管具有很大的实用性，但由于成本限制，混合氧化物在生物医学以外的市场中的应用有限。 我们已经获得了初步数据，证明了一种新的、高效且低成本的材料制造方法，该方法使用精确的流动和混合控制来在纳米尺度上组装混合氧化物的各个成分。 该过程利用容易获得的廉价纳米材料成分（例如胶体）。 该过程产生复杂的“核-壳”纳米材料，然后进一步加工以产生功能大大增强的混合氧化物。 我们预计这些材料将表现出不透射线（帮助诊断能力）和生物活性（更好的植入物集成）等商业上重要的特性。该项目更广泛的影响/商业潜力是提供更好地融入人体的生物医学植入物，加速愈合过程，提高耐用性，延长使用寿命并帮助诊断。 这最终将降低翻修手术的发生率并改善患者的治疗效果。 与现有的制造方法相比，该工艺具有许多显着的优势，包括增加功能、显着提高产品产量（从而降低成本）以及显着提高性能。 与现有材料相比，该工艺具有显着的制造成本优势，并且可以进一步利用将市场机会扩大到成本限制限制了先进复合材料采用的邻近领域。
