General description

Silicon dioxide based microparticles are ideal to determine particle size distribution (PSD) profile of test samples.
The particle diameter of 5 μm is measured using Coulter Multisizer.

Application

Used for regular calibration and checking of particle size instruments. Also used:
  • to study transport properties of microscopic particles via heterogeneous media
  • as a test standard to validate denoising method used in optical diffraction tomography
  • in accelerated annealing experiments involving colloidal silica monolayers
  • to evaluate the measurement accuracy of color-coded LED microscopy (cLEDscope) technique
  • as a calibration standard in optical trapping system to measure surface mechanical properties

Features and Benefits

  • suitable for routine instrument calibration monitoring, testing and corrections
  • particle size traceable to Community Bureau of Reference (BCR) standards
  • available in 5 mL pack size as a neat sample

Molecular motors are essential to the living, generating fluctuations that boost transport and assist assembly. Active colloids, that consume energy to move, hold similar potential for man-made materials controlled by forces generated from within. Yet, their use as a powerhouse

We combine experiments and numerical simulations to investigate the emergence of clogging in a system of interacting paramagnetic colloidal particles driven against a disordered landscape of larger obstacles. We consider a single aperture in a landscape of immobile silica particles

Optical diffraction tomography (ODT) is a three-dimensional (3D) quantitative phase imaging technique, which enables the reconstruction of the 3D refractive index (RI) distribution of a transparent sample. Due to its fast, non-invasive, and quantitative imaging capability, ODT has emerged as

In optical tomography, there exist certain spatial frequency components that cannot be measured due to the limited projection angles imposed by the numerical aperture of objective lenses. This limitation, often called as the missing cone problem, causes the under-estimation of
