General description

Silicon dioxide-based microbeads (size: 0.5 μm) are ideal for profiling particle size distribution (PSD) of a particle system.

Application

Silicon dioxide beads, 0.5 μm have a wide range of uses from use as a flow agent to electrical and medical applications.
Used to qualify, validate and monitor particle sizers and surface scanning equipment.
Also used to fabricate silicon-based nano-electro-mechanical systems (NEMS) for mass sensing application.

Features and Benefits

  • suitable for routine instrument calibration checks, testing and corrections
  • available in 5 and 10 mL pack sizes as neat samples

Micron-sized particles have primarily been used in microfabricated flow cytometers for calibration purposes and proof-of-concept experiments. With increasing frequency, microparticles are serving as a platform for assays measured in these small analytical devices. Light scattering has been used to measure

This paper explores the particle-level dynamics involved in the capture of gently flowing microparticles on adhesive planar surfaces, governed by electrostatic interactions. The work focuses on conditions which produce sustained microparticle rolling, useful for the development of microfluidic devices which
