项目摘要

This Accelerating Innovation Research Technology Translation project focuses on translating a novel biosensor technology into a proof-of-concept for an early stage prototype for direct screening of vegetative crop diseases. The innovation addresses an important and unmet need in the agricultural industry, as there is no early crop disease detection tool presently available in the market. The technology focuses on the development of an enzyme based electro-chemical biosensor for highly selective, ultra-low level detection of volatile markers released by plants during pathogen infections. Currently used methods for disease detection in agricultural crops are time consuming, destructive, demand skilled analysts, and do not offer real time monitoring or on-field deployment possibilities. A rapid, real-time, non-destructive, ex-situ method for early detection of infections will help crop producers to locate and contain the infection, prevent the spread of disease, spray chemicals selectively and timely and hence avoid colossal crop damage. The proposed technology could fundamentally transform the approach towards disease management and precision agriculture. This project addresses the following technology gap(s) as it translates from fundamental discovery to a proof-of-concept an early stage prototype: (1) Development of paper based sensor strips using ink-jet printing with multilayered biosensor platform. (2) Testing and evaluating paper based sensor strips using real volatile organic compounds released by diseased plants. In addition, the project will provide entrepreneurship and technology transition training to a post-doctoral research assistant.

这个加速创新研究技术转化项目的重点是将一种新的生物传感器技术转化为直接筛查营养作物疾病的早期原型的概念验证。该创新解决了农业行业中一个重要且未满足的需求，因为目前市场上没有早期作物病害检测工具。该技术的重点是开发基于酶的电化学生物传感器，用于高选择性，超低水平检测植物在病原体感染期间释放的挥发性标记物。目前使用的农作物疾病检测方法是耗时的、破坏性的，需要熟练的分析师，并且不提供真实的时间监测或现场部署的可能性。一种快速、实时、非破坏性、异位的早期检测感染方法将有助于作物生产者定位和控制感染，防止疾病传播，有选择地及时喷洒化学品，从而避免巨大的作物损失。拟议的技术可以从根本上改变疾病管理和精准农业的方法。该项目解决了以下技术差距，因为它从基础发现转化为早期原型的概念验证：（1）使用喷墨打印与多层生物传感器平台开发纸基传感器条。(2)使用患病植物释放的真实的挥发性有机化合物测试和评估纸基传感器条。此外，该项目还将为一名博士后研究助理提供创业和技术过渡培训。
