This NSERC Engage Grant application will initiate a short-term collaborative project between Dr. Yu's**research team at Simon Fraser University and a local manufacturing company, Laca Biotech Inc. to develop a**mobile analytical device for the on-site colorimetric quantitation of anthocyanins in fruit beverages.**Anthocyanins are water-soluble red, purple, and blue plant pigments found mostly in fruits and flowers; their**reported antioxidant activities are associated with health claims such as increased longevity, improved**cardiovascular function, and prevention of cancer/dementia. The proposed mobile analytical device will enable**small-scale producers and wineries to perform reliable assessment of the quality of both raw materials and final**products, and to evaluate manufacturing practices. As existing techniques typically require advanced**instrumentation, intensive sample preparation, and employment of trained personnel, the on-demand portable**device will offer immense advantages in terms of low cost of fabrication, rapid detection, and adaptation of**consumer electronics (smartphone/pad/scanner).**Particularly, the research will focus on the design and testing of a bench-top microchip, which will employ the**pH-differential method established by the Association of Analytical Communities in 2005. The new device will**be validated against the established spectrophotometric protocol and other laboratory techniques such as liquid**chromatography and electrophoresis for anthocyanin quantitation in both standards and beverage samples.**Successful completion of this project will develop ties and foster relationship between SFU and Laca Biotech**Inc., and lead to expanded collaborations in applied analytical chemistry for quality control in food and**beverage industries locally and nationally. The execution of this project will also provide great R&D training**opportunities for graduate students at SFU and research technicians from local industry.

这项NSERC参与资助申请将启动西蒙弗雷泽大学余博士 ** 研究团队和当地制造公司Laca Biotech Inc.之间的短期合作项目。开发 ** 移动的分析装置，用于水果饮料中花青素的现场比色定量。**花青素是一种水溶性的红色、紫色和蓝色植物色素，主要存在于水果和花卉中;它们的抗氧化活性与健康声明有关，如延长寿命、改善心血管功能和预防癌症/痴呆症。拟议的移动的分析设备将使 ** 小规模生产者和酿酒厂能够对原材料和最终 ** 产品的质量进行可靠的评估，并评估制造方法。由于现有技术通常需要先进的 ** 仪器、密集的样品制备和训练有素的人员的雇用，按需便携式 ** 设备将在低制造成本、快速检测和适应 ** 消费电子产品（智能手机/平板电脑/扫描仪）方面提供巨大的优势。特别是，研究将集中在一个台式微芯片的设计和测试，这将采用 ** pH值差示法建立的分析社区协会在2005年。新设备将 ** 根据已建立的分光光度法协议和其他实验室技术进行验证，如液体 ** 色谱法和电泳法，用于标准品和饮料样品中的花青素定量。该项目的成功完成将发展SFU和Laca Biotech**Inc.之间的联系和促进关系，并导致扩大合作，在应用分析化学质量控制在食品和 ** 饮料行业的地方和国家。该项目的实施也将为SFU的研究生和当地工业的研究技术人员提供很好的研发培训机会。
