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.

这个小企业创新研究（SBIR）第一阶段项目将开发和测试一系列基于表面增强拉曼散射（Sers）的隐蔽纳米级标签剂，用于印刷文件和包装的认证。 Sers纳米标签由一个金核，一个有机标记分子和一个玻璃涂层组成。 这些50 nm直径的颗粒产生独特的指纹状光谱特征，其读数基于表面增强拉曼散射。 在该项目期间进行的任务将：（1）确定将Sers纳米标签添加到纸张和油墨中作为隐蔽标签的可行性，（2）定义商业上成功的手持式检测系统所需的仪器参数，以及（3）开发新的软件算法以实现标签识别。 在这项工作中提出的纳米技术，光学工程和软件设计的成功结合，提出了一个新的解决方案，在商业市场上的产品认证，并有可能作为一个隐蔽的标签在国家安全的问题。 商业Sers纳米标签将在许多商业和政府部门产生广泛的影响，因为假冒会影响各种各样的产品。 对零售产品包装的保护可以为企业节省数百万美元，从而为经济节省数百万美元。 此外，伪造货币威胁到我国的安全，因为恐怖主义集团越来越多地将伪造货币作为资助其活动的一种方法。 保护货币不被伪造可以为政府节省数百万（如果不是数十亿）美元（或欧元）。 保护药品不被假冒可以为法律的制药业节省数百万美元，并保护消费者免受无效药物的消费。 保护旅行证件，包括护照和签证，可以保障国家安全。
