In which of the following are hydrogels used ?
Controlled drug delivery in patients Mobile air-conditioning systems Preparation of industrial lubricants Select
the correct answer using the code given below: (a). 1 only (b). 1 and 2 only (c). 2 and 3 only (d). 1, 2 and 3 Explanation: Hydrogels are water-absorbent polymer
networks that can be used in a variety of applications, including: Controlled drug delivery: Hydrogels can encapsulate
drugs and release them gradually over time, which can help reduce the dose and
dosing frequency and improve patient compliance. Mobile air-conditioning systems:
Hydrogels can be used as desiccants to control humidity. Industrial lubricants: Hydrogels can
improve the properties of industrial lubricants, such as reducing friction and
wear, controlling viscosity, and improving thermal stability. Hydrogels are biphasic materials that are
a mixture of porous, permeable solids and at least 10% by weight or volume of
interstitial fluid composed completely or mainly by water. Many hydrogels are
synthetic, but some ar…
