Physical Separation Methods

Centrifugation depends on the shape, size, and density of particles, viscosity (thickness) of the liquid medium, and speed at which the centrifuge is rotated. This method of separation is used when very tiny solid particles are suspended in a liquid medium. The principle on which a centrifuge works is that the denser particles remain at the bottom while the lighter particles .

Nanoparticle: An overview of preparation and characterization

particles can be isolated by centrifugation at high speed. The formed nanoparticles must be thoroughly washed before lyophilisation (Vandervoort et al., 2002).In this method the amount of hydrophilic drug to be incorporated, the concentration of stabilizer used, the polymer concentration, the volume of aqueous phase are the variables that affect the characterization .

What Is TRIzol Reagent?

TRIzol ® reagent is an acidguanidiniumphenol based reagent ideally designed for the extraction of RNA (as well as DNA and protein) from various biological sample inputs. The low pH (acidic) of TRIzol ® controls to separate RNA from DNA and protein, while a high pH can cause RNA and DNA to be isolated together. The guanidinium salt serves as a chaotropic agent to denature .

Gold's new golden moment

The race is on. The industry needs to discover more economically viable means of extracting gold from refractory, lowgrade ores and thereby increase reserves. Since 2012, there have been less than ten major gold deposits discovered globally. Looking at the five years prior to 2012, the number of major discoveries was nearly four times as high.

A Centrifugationbased Method for Preparation of Gold ... Gold nanoparticles (AuNPs) have found widespread appliions in lifesciences. While synthesis of monodispersed AuNPs has been fairly convenient by usingchemical reduction of chloroauric acid by sodium citrate, we found that AuNPs of highquality and high concentrations were not readily obtained via this method.
