Gregory F. Payne0650650This activity is in the field of biosensors individually functionalized to allow recognition to be transduced through redundant optical and electrical signals. The work is broadly applicable, but especially relevant for food analysis where speed, reliability and cost are paramount. The approach, based on the use of chitosan, is original and could lead to important developments with easy transfer to industry, thus covering not only progress in fundamental science, but also promising applications. In this work, three model analyses will be studied: electrochemical sensing, enzymatic biosensing, and immunosensing. It is expected that this research will result in new fundamental contributions to biotechnology, electrochemistry, and materials science as well as other fields.The PI will integrate the research with outreach activities that target K-12 students and teachers. The students will benefit from hands-on learning modules of natural materials, health and nutrition and food technology. On-site laboratory training will meet the increasing interest of the students in biotechnology and biomaterials. This training will enhance the participation of underrepresented groups.

这种活动是在生物传感器领域的单独功能化，允许识别通过冗余的光学和电子信号进行转换。这项工作广泛适用，但尤其适用于速度、可靠性和成本至关重要的食品分析。该方法基于壳聚糖的使用，具有独创性，可以导致重要的发展，易于转移到工业上，从而不仅涵盖基础科学的进步，而且具有前景的应用。在这项工作中，将研究三种模型分析：电化学传感、酶生物传感和免疫传感。预计这项研究将对生物技术、电化学、材料科学等领域产生新的基础贡献。PI将把研究与针对K-12学生和教师的外展活动结合起来。学生将从自然材料、健康和营养以及食品技术的实践学习模块中受益。现场实验室培训将满足学生对生物技术和生物材料日益增长的兴趣。这种培训将加强代表人数不足的群体的参与。
