    • A method for storing and coding information which utilizes mixtures of metal nanoclusters with dyes and other Raman-active substances is disclosed. A method for reading and decoding the stored information by measuring the Raman spectra is also disclosed. To code and store information, a plurality of dots or markers, each consisting of a mixture of two or more Raman-active substances taken in different proportions, is applied on a on object. The number of substances in the mixture and the relative quantities of each substance in the mixture carry the information to coded by each dot. By scanning a sequence of dots on the object, information stored in the sequence can be read and decrypted. Surface enhanced Raman scattering associated with metal nanoclusters and large Raman cross section of colored Raman-active substances make it more feasible to detect the Raman signal from a single dot of a small size (up to the diffraction limit) on the millisecond time scale.
    • 公开了一种利用金属纳米簇与染料和其他拉曼活性物质的混合物来存储和编码信息的方法。 还公开了通过测量拉曼光谱读取和解码存储的信息的方法。 为了编码和存储信息,将多个点或标记,各自由以不同比例取得的两种或更多种拉曼活性物质的混合物组成。 混合物中的物质数量和混合物中每种物质的相对数量都携带每个点编码的信息。 通过扫描对象上的点序列,可读取和解密序列中存储的信息。 与金属纳米团簇相关的表面增强拉曼散射和有色拉曼活性物质的大拉曼截面使得从毫秒级的小尺寸(直到衍射极限)的单个点检测拉曼信号更为可行。
