This Small Business Innovation Research (SBIR) Phase I project will develop and test a series of covert, nanoscale taggants based on Surface Enhanced Raman Scattering (SERS) for use in the authentication of printed documents and packages. SERS nanotags consist of a gold core, an organic label molecule and a glass coating. These 50 nm diameter particles generate unique fingerprint like spectral signatures, with a readout based on surface enhanced Raman scattering. The tasks carried out during this project will: (1) determine the feasibility of adding SERS nanotags to paper and inks, as covert tags, (2) define the instrument parameters needed for a commercially successful hand held detection system and (3) develop novel software algorithms to enable tag identification. The successful combination of nanotechnology, optical engineering, and software design proposed in this work present a new solution for product authentication in the commercial markets, and have the potential to act as a covert tag in matters of national security. Commercially SERS nanotags will have a broad impact across many commercial and government sectors, because counterfeiting affects such a wide variety of products. The protection of packaging on retail products can save corporations, and hence the economy, millions of dollars. In addition, counterfeiting threatens the security of our country as terrorist groups are increasingly turning to counterfeiting as a method to fund their activities. The protection of currency against counterfeiting can save governments millions (if not billions) of dollars (or Euros). The protection of pharmaceuticals against counterfeiting can save the legal pharmaceutical industry millions of dollars and protect consumers against the consumption of ineffective drugs. The protection of travel documents, including passports and visas, can safeguard national security.

这项小型企业创新研究（SBIR）I阶段项目将根据表面增强的拉曼散射（SER）（SER）开发和测试一系列秘密的纳米级标签，以用于对印刷文档和包装的身份验证。 SERS纳米塔由金芯，有机标签分子和玻璃涂层组成。 这50 nm直径的颗粒会产生独特的指纹，例如光谱特征，其读数基于表面增强的拉曼散射。 该项目期间执行的任务将：（1）确定将SERS纳米塔添加到纸张和油墨中的可行性，作为掩护标签，（2）定义商业上成功的手持手持式检测系统所需的仪器参数，以及（3）开发新型软件算法以启用标签标签。 这项工作中提出的纳米技术，光学工程和软件设计的成功组合为商业市场中的产品身份验证提供了新的解决方案，并有可能充当国家安全事务的秘密标签。 商业上的纳米塔将对许多商业和政府部门产生广泛的影响，因为伪造会影响各种各样的产品。 保护零售产品的包装可以节省公司，从而节省数百万美元的经济。 此外，伪造会威胁到我国的安全，因为恐怖组织越来越多地转向伪造，以此作为资助其活动的一种方法。 货币免受伪造的保护可以为政府节省数百万美元（如果不是数十亿美元）的美元（或欧元）。 保护药物免受伪造的保护可以节省法律制药行业数百万美元，并保护消费者免受无效药物的消费。 保护包括护照和签证在内的旅行文件可以保护国家安全。
