Kinetics of phytochemical adsorption and desorption in clay nanoparticles

具有生物活性的植物化学物质在人类活动的许多领域日益重要。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释放速度的控制和对紫外线击穿的一般敏感性。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。通过对特定植物化学物质的吸附和解吸动力学的研究，我们旨在建立纳米颗粒粘土载体体系和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、缓解植物胁迫和促进生长等领域得到广泛应用。

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.
