Question

Nitrocellulose and nylon are used in which of the following technique of immobilisation?

• A. Entrapment
• B. Encapsulation
• C. Adsorption
• D. Cross-linking

Answer 1

The correct option is C Adsorption

• Nitrocellulose and nylon is a medium used in blotting of DNA and proteins are adsorbed into the membrane of nitrocellulose by charge interactions.
• Encapsulation is a method of enzyme immobilization that is done by enclosing the enzyme molecule inside a capsule.
• Entrapment is a method used for cell or enzyme immobilization into the 3-D matrix of high-molecular compounds.

So the correct answer is "Adsorption".
