Zeta potential is a key indicator of the stability of colloidal dispersions and nanoparticle suspensions. It measures the electrical potential difference between the bulk of the liquid and the ...

The zeta potential of polyethylenimine (PEI) is measured as a function of polymer concentration with the SZ-100 Nanoparticle Analyzer. There is a negative relationship between Zeta potential and ...

Nanoparticles of increasingly smaller particle size and various material compositions are being developed for the pharmaceutical, biomedical, electronics, optoelectronics, energy, catalyst and ...

What is zeta potential? When suspending particles in a liquid medium, the surface charges attract the counterions in the liquid and become attached to the particle surface, forming a firmly fixed ...

Malvern has announced it will be holding a new webinar to explain the use of electrophoretic light scattering (ELS) to measure the electrophoretic mobility of particles or molecules in a solution.

Formulation development is an important activity for a wide range of industries, from paints and coatings to pharmaceuticals. In the UK alone, it has been estimated that sales of formulated products ...

The building blocks of proteins are amino acids. Each protein molecule often contains 300 or more amino acids, and proteins have 20 different amino acids commonly found within them. This means that ...
