 Hydrogels have been studied extensively in recent years for their potential applications in drug delivery and cell encapsulation. They are biodegradable, making them ideal for biocompatible materials. Additionally, they can be chemically or physically crosslinked, with chemical crosslinking being more common due to its ease of use. However, some of these crosslinkers may be toxic, so it is important to remove them prior to use. Physically crosslinked gels are also possible, but require more time and effort to prepare.
