Frequently Asked Questions:


1. What is the function of cetyl trimethyl ammonium bromide?


Ans: It is use for forming buffer solution that enables to extract DNA. Also, it is being used for the preparation of gold nanoparticles which can be made into a number of shapes such as: spheres, rods, and bipyramids.


2. What type of detergent is cetyl trimethyl ammonium bromide?


Ans: A cationic detergent, cetyltrimethylammonium bromide (CTMAB), selectively dissociates the intermediate filament of the fibroblast.


3. What is cetyl trimethyl ammonium bromide method generally used for?


Ans: It is a surfactant useful for isolation of DNA from tissues containing high amounts of polysaccharides.


4. What are the risks of CTAB?


Ans: It causes eye burns. Inhalation can be harmful if inhaled. It causes respiratory tract irritation. Skin may be harmful if absorbed through skin.


5. Why CTAB is used in nanoparticles?


Ans: It is a common surfactant used in nanoparticles synthesis. It has a 16-carbon as a long tail and an ammonium head group with three methyl groups attached. Here, CTAB can be used for the removal of heavy metals from wastewater.
