Here we propose tunable resistive pulse sensing for simultaneous size and surface charge measurements on a particle-by-particle basis, enabling the analysis of a wide spectrum of nanoparticles and their mixtures. Existing methodologies for measuring zeta potential of nanoparticles using resistive pulse ...
the intensity of scattered light fluctuates at a frequency proportional to the particle speed. The particle speed at multiple voltages is measured, and this data is used to calculate the zeta potential.The zeta potential of the nanoparticles measures lower around or less than −28mV, so we can...

Zeta potential affects the absorbance of a material by influencingthe interaction between the particles and the incident light. For example, let's consider a colloidal suspension of nanoparticles with a high zeta potential. Due to the repulsive forces between the particles, they remain dispersed and...
