Biologically active phytochemicals are of increasing importance in many areas of human endeavour. There is a growing interest in the agricultural uses of such compounds. A major limiting factor has been the control of the release rate and the general susceptibility to UV breakdown. This project aims to develop a platform technology for the controlled release and for improved UV protection of these chemicals. Through the studies on the adsorption and desorption kinetics of select phytochemicals, we aim to develop a nanoparticle clay based carrier system and a predictive model for control of the desorption characteristics. Such a platform technology will enable wide range of applications of phytochemical products in pesticides, plant stress alleviating and growth enhancing areas.

具有生物活性的植物化学物质在人类努力的许多领域中越来越重要。人们对这类化合物的农业用途越来越感兴趣。一个主要的限制因素是对释放率的控制和对紫外线击穿的总体敏感性。该项目旨在开发一种平台技术，用于控制释放和改善这些化学品的紫外线防护。通过对部分植物化学物质的吸附和解吸动力学的研究，我们的目标是开发一种基于纳米粘土的载体系统和一个控制解吸特性的预测模型。这样的平台技术将使植物化学产品在农药、植物胁迫缓解和生长促进领域得到广泛应用。
