Controlled release of active compounds from nanocapsule polymers

利用纳米胶囊和纳米颗粒在农业和生物医学应用中递送活性化合物（AIs）的研究一直在积极进行。然而，由于这些纳米颗粒的大小，对ai释放的量化一直存在问题。为了测量从纳米颗粒中释放的AI的浓度，必须将装载AI的纳米颗粒从散装溶液中分离出来。两种常用的技术，即离心和过滤，但它们存在许多问题，例如AI的强制释放，过滤器上的吸附和毛孔堵塞。因此，需要开发一种更可靠和更准确的替代方法来促进这种测量。最近，Tam和同事已经证明电动势（EMF）测量可以很容易地用于执行此类测量。他们已经证明了所提出的方法是准确的和简单的实现。这个

The use of nanocapsules and nanoparticles in the delivery of active compounds (AIs) in agriculture and biomedical applications has been actively pursued. However, the quantification of the release of AIs has been problematic due to the size of these nanoparticles. In order to measure the concentration of AI released from the nanoparticles, the AI loaded nanoparticles have to be separated from the bulk solution. Two common techniques are used, namely centrifugation and filtration, but they present numerous problems, such as forced release of AI, adsorption on filters, and blockage of pores. Thus, an alternative method that is more reliable and accurate needs to be developed to facilitate such measurements. Recently, Tam and co-workers have demonstrated that the Electromotive Force (EMF) measurements can be readily used to perform such measurements. They have demonstrated that the proposed method is accurate and simple to implement. The
