项目摘要

We are proposing to purchase a Nanobrook Omni particle size and zeta potential analyzer that performs simultaneous dynamic light scattering (DLS) and phase analysis light scattering (PALS) to determine particle size and zeta potential with high accuracy and precision. An instrument with these capabilities is not available at Carleton University. This instrument will provide an economical, real-time analysis, eliminating more complex analytical procedures for particle characterization (e.g., Cryo-SEM (Scanning Electron Microscopy)). The Nanobrook Omni particle size and zeta potential analyzer characterizes emulsions, nanomaterials, peptides and oligonucleotides, including hydrophobic/hydrophilic properties of particles in food, drug, biological and environmental samples. This instrument is urgently needed by members of four academic units (Chemistry, Biology, Biochemistry and Engineering) that span the Natural Sciences and Engineering (NSE) within Carleton University. The state-of-the-art instrument will enable advanced surface chemistry research in food science, chemical toxicology, membrane biochemistry and biological systems, environmental chemistry, and polymer engineering studies. The proposed instrument will facilitate training of 40 highly qualified personnel (HQPs) in the short-term and ~450 HQPs over the next five years, supporting interdisciplinary NSE-sponsored research.

我们建议购买Nanobrook Omni粒度和zeta电位分析仪，该分析仪可同时进行动态光散射（DLS）和相分析光散射（帕尔斯），以高准确度和精密度测定粒度和zeta电位。卡尔顿大学没有具有这些功能的仪器。该仪器将提供经济的实时分析，消除用于颗粒表征的更复杂的分析程序（例如，Cryo-SEM（扫描电子显微镜））。Nanobrook Omni粒度和zeta电位分析仪可表征乳液、纳米材料、肽和寡核苷酸，包括食品、药物、生物和环境样品中颗粒的疏水/亲水特性。该仪器是迫切需要的四个学术单位（化学，生物学，生物化学和工程），跨越自然科学和工程（NSE）在卡尔顿大学的成员。先进的仪器将使先进的表面化学研究在食品科学，化学毒理学，膜生物化学和生物系统，环境化学和聚合物工程研究。拟议的工具将有助于在短期内培训40名高素质人员（HQP），并在未来五年内培训约450名HQP，支持NSE赞助的跨学科研究。
