Zeta potential is a very important parameter in nanotechnology and in the study of dispersion and aggregation of particles and polymers. The zeta potential analyzer can provide crucial information on the repulsive or attractive forces among charged particles and other chemical and biochemical species. The understanding of such properties is essential in our research on colloidal crystalline arrays and liposomes for use as biosensors and drug delivery systems. This instrument is urgently needed by the students and researchers to analyze the samples prepared in our labs at Université de Montréal.The zeta potential analyzer can also monitor the evolution of electrostatic forces as a function of external conditions. It helps to predict the phenomenon of aggregation and packing of nanoparticles under different conditions. The determination of the zeta potential provides guidelines on the stability and application range of the materials, which helps to save research time in the development of new materials. In our work, the analyzer will be used in the study of charges and charge density as a function of particle size, composition, pH and temperature for polymeric particles, liposomes and ionic polymers developed in our research projects. The equipment will be made available to other researchers and will be used in the training of young researchers.

Zeta电位是纳米技术和研究粒子和聚合物的分散和聚集的一个非常重要的参数。Zeta电位分析仪可以提供带电粒子和其他化学和生物化学物质之间的排斥力或吸引力的关键信息。这些性质的理解是必不可少的，在我们的研究胶体晶体阵列和脂质体作为生物传感器和药物输送系统。这款仪器是蒙特利尔大学的学生和研究人员急需的，用于分析我们实验室制备的样品。zeta电位分析仪还可以监测静电力随外部条件的变化。这有助于预测纳米粒子在不同条件下的聚集和堆积现象。Zeta电位的测定为材料的稳定性和应用范围提供了指导，有助于节省新材料开发的研究时间。在我们的工作中，该分析仪将用于研究我们研究项目中开发的聚合物颗粒、脂质体和离子聚合物的电荷和电荷密度随粒径、组成、pH值和温度的变化。这些设备将提供给其他研究人员，并将用于培训青年研究人员。
