Nanoparticle Analysis with Izon

qNano uses unique nanopore-based detection to enable the physical properties of a wide range of particle types to be accurately measured.

Particle-by-particle measurement through qNano enables detailed determination of:


Nanopore-based detection allows thousands of particles to be measured individually, providing far greater detail and accuracy than light-based techniques.

qNano uses Tunable Resistive Pulse Sensing (TRPS) to enable:

  • Evaluation of Absolute Particle Size
  • Accurate Size Distribution of Polydisperse Samples
  • Improved Accuracy Over Light-based Techniques
  • Analysis of Aggregation Effects & Dynamics


  • Size range of particles: 50 nm to 10 Micrometer
  • Useable for practically all types of materials
  • Minimal sample volume needed (40 microliter)
  • Polydisperse samples are well measurable
  • Portable device

Comparison SEM Image – qNano Analysis:

The SEM image below clearly shows 3 different particle diameters. The corresponding qNano analysis finds These 3 Population with high resolution.

The Swiss company InnoMedica uses the qNano successfully for liposomes development and quality control. Please click on the image below to see a short report of the Swiss Television (in French). The qNano is shown in the middle of the film.
