Advancements in biomedical engineering: developing hydrogels for tissue regeneration and drug delivery

Hydrogels are a 3-D network of highly absorbent polymers that have been investigated since the late 20th century for various biomedical applications, including drug delivery, wound healing, and tissue engineering. Their highly absorbent nature gives them a flexibility similar to natural tissues and allows oxygen, nutrients, proteins, and other biomolecules to readily enter and nourish
