The purpose of this guide is to demonstrate the proper method for preparing a zeta potential validation sample used for checking the performance of the NanoBrook ZetaPlus, ZetaPALS, 90PlusPALS, and Omni instrumentation. The BI-ZR5 validation material is a dark blue, inorganic powder that is insoluble in water. It has a mean particle size of approximately 300 nm...Read More
Liposomes are commonly used in drug delivery applications to encapsulate and deliver bioactive cargo molecules such as oligonucleotides and proteins. A new application is available that discusses how Liposomes may be characterized using Dynamic Light Scattering (DLS) and Zeta Potential techniques...Read More
The stability of dispersible nanomaterials often depends on having a high surface charge. These charges are often pH dependent, especially for surface chemistries with acidic or basic functionalities. A titration can be performed to rapidly profile a range of solution conditions to determine...Read More
Zeta potential is a useful property to know for colloids, nanoparticles, and proteins. It is a substitute for the otherwise hard to measure surface charge... Read More
