Types Of Emulsions Emulsions are a type of colloid where two immiscible liquids are dispersed together, with one liquid (the dispersed phase) being finely dispersed as droplets within the other liquid (the continuous phase). There are several types of emulsions based on the nature of the dispersed and continuous phases. Here are some common types…
Electrophoresis Electrophoresis is a laboratory technique used to separate charged particles, such as proteins, DNA, and RNA, based on their size, charge, or other properties. It is a fundamental method in molecular biology, biochemistry, and related fields. The principle of electrophoresis is based on the movement of charged particles in an electric field. When an…
Brownian movement Brownian movement, also known as Brownian motion, refers to the random motion of microscopic particles suspended in a fluid (liquid or gas). It was first observed by the Scottish botanist Robert Brown in 1827 while studying pollen grains suspended in water. The movement is named after him. Here are some key points about…
