Acquisition Zeta Potential Particle Size

项目摘要

This award is supported by the Major Research Instrumentation (MRI) and the Chemistry Research Instrumentation (CRIF) Programs. Professor Merlis Alvarez-Berrios from the Inter American University Puerto Rico, Ponce Campus and colleague Edmy Ferrer-Torres have acquired a zeta potential and particle size analyzer. The zeta potential is a term used in the electrokinetic studies of colloidal dispersions. This instrument is also used in the investigation of very small aggregates called nanoparticles. It is used to determine particle size and zeta potential critical for understanding of various materials. The size of nanoparticles plays a key role in their unique properties. The zeta potential value is related to the stability of nanoparticles and hence their product performance. Moreover, the analyzer provides multiple accessories and therefore is suitable for a wide spectrum of user applications. These characterization studies are crucial for evaluating the potential application of novel materials in areas such as medicine, technology and the petroleum field. One application is the study of microparticle-protein interactions which may be of potential interest in medicine. The instrument also contributes to training students in modern instrumentation. It is supporting interdisciplinary undergraduate research and education at the Inter American University of Puerto Rico, at both the Ponce Campus and San German campuses, as well as high schools and colleges from the south region of Puerto Rico.The instrument is employed in supporting research in a number of projects to accurately predict and quantify the stability of nanoparticles. Metallic nanoparticles are of special interest in these studies. The instrument is being used to elucidate protein-protein and microparticle-protein interactions governing the inhibition of fibrillation processes. Modification of solid surfaces is being studied. Confirmation of the functional groups present on the surface of the nanomaterials suspended in liquids after chemical modification is under investigation. The instrument is also being used to determine the electrostatic interactions between particles and flat surfaces.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项由主要研究仪器（MRI）和化学研究仪器（CRIF）计划支持。来自美洲大学波多黎各庞塞校区的Merlis Alvarez-Berrios教授和同事Edmy Ferrer-Torres获得了zeta电位和粒度分析仪。zeta电位是用于胶体分散体的电动研究中的术语。该仪器还用于研究称为纳米颗粒的非常小的聚集体。它用于测定粒度和zeta电位，这对了解各种材料至关重要。纳米颗粒的尺寸在其独特的性质中起着关键作用。zeta电位值与纳米颗粒的稳定性相关，因此与其产品性能相关。此外，该分析仪提供多种附件，因此适用于各种用户应用。这些表征研究对于评估新材料在医学、技术和石油领域等领域的潜在应用至关重要。一个应用是研究微粒-蛋白质相互作用，这可能在医学上具有潜在的意义。该仪器还有助于培养学生的现代仪器。该仪器支持波多黎各美洲大学庞塞校区和圣日耳曼校区以及波多黎各南部地区的高中和大学的跨学科本科研究和教育。该仪器用于支持多个项目的研究，以准确预测和量化纳米颗粒的稳定性。金属纳米颗粒在这些研究中特别令人感兴趣。该仪器被用来阐明蛋白质-蛋白质和微粒-蛋白质的相互作用，控制抑制原纤化过程。固体表面的改性正在研究中。目前正在调查化学改性后悬浮在液体中的纳米材料表面上存在的官能团的确认。该仪器还被用于确定颗粒与平面之间的静电相互作用。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
