Dynamicity of hydrogels and their diverse biological applications

Ever increasing use of hydrogels in various sectors of biology imposes the need of rigorous study of various aspects related to it. Its compatibility with the biological system makes it suitable candidate to achieve any complex application of such hydrogels in living systems. Depending upon the need, it can be modified chemically which in turn gives it desired physical properties. These modifications enable us the wide spectrum use of hydrogels for various purposes. Nature of response given by prepared hydrogels greatly varies according to the protocol followed while preparing such hydrogels. Slight change in the composition of hydrogels changes its properties and forms entirely new features bearing form. The overall architecture of hydrogel is designed in such a manner that it can be applicable in various regenerative and biomedical applications and still further modified to be used in novel different application fields. This review highlights preparation techniques being followed to fabricate hydrogels which are having major applications in biological fields. Properties of various hydrogels depending upon their compositions and material which give them new face and can be extrapolated to the new research area have also discussed further
