SBIR Phase I: Colorimetric Detection in Aqueous Solutions

这个小型企业创新研究第一阶段项目拥有一种独特的化学检测技术，其中染料阵列中的色度变化构成了一种信号，非常类似于哺乳动物嗅觉系统产生的信号;每种染料都是一种交叉响应传感器。这项技术最近已经扩展到检测含水分析物的领域，用作电子舌头-称为TasteSeeing。初步结果表明，近瞬时，生动的响应，从小的解决方案样本，大多数的阵列似乎是强大的在水中。该I期项目旨在评估该技术作为表征水溶液的方法的灵敏度、特异性和重现性。这项技术虽然对广泛的市场有吸引力，但最初将集中于检测和识别潜在的恐怖化学制剂，目标是将TasteSeeing技术集成到一个便携式和廉价的设备中，以快速检测水和其他液体中溶解的低水平化学品。

This Small Business Innovation Research Phase I project possesses a unique chemical detection technology in which colorimetric changes in an array of dyes constitute a signal much like that generated by the mammalian olfaction system; each dye is a cross-responsive sensor. This technology has recently been expanded into the realm of the detection of aqueous analytes for use as an electronic tongue - dubbed TasteSeeing. Preliminary results indicate that near-instantaneous, vivid responses are obtained from small solution samples and that the majority of the array appears to be robust in water. This Phase I program is designed to evaluate the sensitivity, specificity and reproducibility of the technology as a methodology to characterize aqueous solutions. This technique, while attractive to a wide range of markets, will initially be focused on the detection and identification of potential terrorist chemical agents.The goal is to integrate the TasteSeeing technology into a portable and inexpensive device to detect rapidly low levels of dissolved chemicals in water and other fluids.
