Question

In which of the following are hydrogels used? Select the correct answer using the code given below:

1.
Controlled drug delivery in patients
2.
Mobile air-conditioning systems
3.
Preparation of industrial lubricants

Options

1 only

1 and 2 only

2 and 3 only

1, 2 and 3

Answer

Explanation

Hydrogels are highly versatile, water-absorbing polymer networks used in all three applications. Their biocompatibility makes them ideal for controlled drug delivery. Their ability to hold and release water facilitates evaporative cooling in air-conditioning systems. Their aqueous nature and low friction properties make them effective industrial lubricants.

Hydrogels' fundamental property—the ability to hold vast amounts of fluid while maintaining structure—enables biomedical, thermal, and mechanical applications.

Answer: (d).
