When light is scattered from a solution or a suspension, it undergoes random changes in intensity. This phenomenon helps us to determine the size of the particles that scatter the light. This is the ...
There are a number of techniques currently used by the pharmaceutical industry for particle size determination. However, most of these are applicable in a visible particle range (> 25 μm) and are ...
If particles of a definite size must be produced it is important that the sample size and shape monodispersity is known. A high-resolution method, such as Transmission Electron Microscopy (TEM), is ...
What Happens During a DLS Measurement? In a DLS measurement, particles diffusing by Brownian motion scatter incident light back to a detector, where interference of the light scattered by every ...
To ensure the stability and usability of injectable biopharmaceutical products, protein aggregation and active principle ingredients (API) are of the utmost concern. Protein aggregation is a process ...
A team of researchers proposed a fast and convenient method called polarized imaging dynamic light scattering (PIDLS) that quantitively evaluates the nanoparticle size, morphology as well as ...
