Two well-funded groups in the Chemistry department of UVic (Moffitt group, van Veggel group) have strong research programs in advanced materials for photonics and bio-imaging based on colloidal systems. We are requesting funds for a zeta potential analyzer, which allows characterization of surface charge of colloidal particles- a fundamental and important parameter that governs interactions and stability in charged colloidal systems.  Recent research advances in both the Moffitt and van Veggel groups have resulted in an increased interest in the potential applications of charged and water-soluble colloids for photonic materials and bio-labels. In such systems, characterization of the zeta potential (and hence the surface charge) is essential to understanding electrostatic interactions and colloidal stability. Despite very promising initial results from both groups, research advances are curtailed in several ways by a critical "blind spot": the current lack of instrumentation to characterize the zeta potential. The proposed instrument is an extremely cost-effective method to provide us with this essential information, and to shed critical light on several exciting projects.

UVic化学系的两个资金充足的小组（Moffitt小组，货车Veggel小组）在基于胶体系统的光子学和生物成像的先进材料方面拥有强大的研究计划。我们正在申请资金的zeta电位分析仪，它允许表征的胶体颗粒的表面电荷-一个基本的和重要的参数，管理在带电的胶体systems.Recent研究进展在两个莫菲特和货车Veggel集团的相互作用和稳定性已导致在带电和水溶性胶体的光子材料和生物标签的潜在应用的兴趣增加。在这样的系统中，zeta电位（因此表面电荷）的表征对于理解静电相互作用和胶体稳定性至关重要。尽管这两个小组的初步结果非常有希望，但研究进展在几个方面受到一个关键的“盲点”的限制：目前缺乏表征zeta电位的仪器。拟议的仪器是一个非常具有成本效益的方法，为我们提供这一基本信息，并揭示了几个令人兴奋的项目的关键光。
