Hydrogel

About Hydrogels:

• It is a three-dimensional network composed of hydrophobic polymers synthesized by crosslinking water-soluble polymers.
• Hydrogels can retain a large quantity of water within their network without disturbing their original structure. This imparts flexibility and swelling properties to the hydrogel structures. 
• It is a “smart” material that can change its structure in response to its environment, such as the local temperature, pH, salt or water concentration.

What is SARS?

• Severe acute respiratory syndrome (SARS) is a viral respiratory disease caused by the virus SARS-CoV-1.
• It is an airborne virus and can spread through small droplets of saliva in a similar way to the cold and influenza.
• It can also be spread indirectly via surfaces that have been touched by someone who is infected with the virus.
• Symptoms of SARS include: Persistent, high fever, Chills, Headache, Body aches.
• Treatment: There’s no established treatment specifically for SARS.

Q1: What is a polymer?

It is any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, which are multiples of simpler chemical units called monomers.
