SBIR Phase II: Universal Nanoparticle Taggants

这个小企业创新研究（SBIR）第二阶段项目将提供一个能够轻松标记文件的系统，该系统具有数百万种独特的光学签名，可以将这些文件与其他类似对象区分开来。由于没有合适的商业替代品，因此将构建和评估扫描光谱仪和高光谱成像系统。开发的材料与当前筛选技术的兼容性，以及大量不同的可解析光学代码，提供了难以复制或解密的认证级别。由于对文件、物品或人员进行鉴定和核实的需求强烈而持续，因此这项技术的好处将是广泛的，并将影响文件、药品或生物样品等许多物品的鉴定、分类和鉴定。用于光学编码技术的商业上可用的多路复用级别（可区分的光学签名数）目前限制在100，因此迫切需要一种技术来提供一种光学区分非常大量相似物体的方法。

This Small Business Innovation Research (SBIR) Phase II project will provide a system that is capable of easily labeling documents, with millions of unique optical signatures that provide a means of distinguishing these documents from other similar objects. Since there are no suitable commercial alternatives, both a scanning spectrometer and hyperspectral imaging system will be constructed and evaluated. The compatibility of developed materials with current screening technology, and the large number of distinct resolvable optical codes available, provides a level of authentication that will be difficult to replicate or decrypt.Since there is a strong and continuing need to authenticate and verify documents, objects or people, the benefits of this technology will be broad-based and will influence authentication, sorting and identification of many items such as documents, pharmaceuticals or biological samples. The commercially available multiplexing level (number of distinguishable optical signatures) for optical encoding technology is currently limited to 100, so there is immediate need for a technology to provide a means of optically distinguishing very large numbers of similar objects.
