我们报告了沉积的纳米结构柱状空隙硅薄膜的各种生物医学应用，包括呼吸监测、蛋白质组学快速质量分析和细胞附着。这些应用利用了我们的纳米结构硅材料的某些独特属性，这些属性是块状硅所不具备的，例如分子固定、与电磁辐射的增强耦合、高表面积和明显的疏水性。根据我们的最新了解，还对形态和薄膜生长进行了简要回顾。我们能够通过改变薄膜生长条件来控制柱状分离和孔隙率，从而可以定制薄膜的性能以及优化应用中的性能。这些薄膜可以沉积在塑料等低加工温度基材上，这一事实进一步增强了它们的多功能性。
We report on various biomedical applications of our deposited nanostructured column-void Si films including respiratory monitoring, quick mass analysis for proteomics, and cell attachment. These applications exploit certain unique attributes of our nanostructured Si material that are not present for bulk Si, such as molecular immobilization, enhanced coupling with electromagnetic radiation, high surface area, and pronounced hydrophobicity. A brief review of morphology and film growth is also given according to our latest understanding. Our capability of controlling columnar separation and porosity by varying film growth conditions allows the tailoring of the properties of our films as well as the optimization of the performance in an application. The fact that these films can be deposited on low processing temperature substrates such as plastics further enhances their versatility.
