Study of Influence of Mie Scattering on Nanoparticles with Different Particle Sizes and Shapes (CAT#: STEM-ST-0074-YJL)

Introduction

Nanoparticles are produced in large quantities for very different applications such as lacquers, dyes, cosmetics, food, magnetic storage materials, catalysts, and print materials. On the other hand, biological systems contain different nanoparticles, e.g., liposomes. An important physical quantity of all nanoparticles is their diameter or, in the case that the nanoparticles consist of different diameters, the particle size distribution. <br />Reliable methods for measuring the above mentioned quantities are photometric measurements and analytical ultracentrifugation with an UV optics detector. Both methods are ruled by the Mie effect, that is scattering and absorption of the particles as function of the diameter, the wavelength, and the shape of the particles.

Principle

Mie scattering is defined as the type of scattering in which the diameter of the particle is the same or more than the wavelength of the radiation. Mie scattering gives a generalized solution for a system where a scattering of light takes place by a homogenous spherical medium. And this medium should have a refractive index different from that of the medium through which the light is traversing.
Unlike Rayleigh scattering, Mie scattering is not a physically independent phenomenon rather, it is a solution to Maxwell's equations for situations where the phase of the incident angle can change within the dimension of the scattering particles. Mie scattering is more commonly known as Mie solution, and it is named after Gustav Mie, a German physicist.
Mie scattering is also known as aerosol particle scattering, takes place in the atmosphere below 1,500 feet. In Mie scattering, the diameter of the spherical particles through which the light is scattered is approximately equal to the wavelength.

Applications

Mie scattering occurs in a variety of applications, including atmospheric science, cancer detection and treatment, metamaterials, and parasitology. Another application is the characterization of particles by optical scattering measurements.
