Use of Hydrogels in Brain Applications

In the last decades, an exponential and rapid evolution has been seen in hydrogel studies. This all started when for the very first-time hydrogels were used in eye surgery. Hydrogels made their way in the medical application because of its biodegradable nature. Now a day’s hydrogels applications can be found in many fields including contact lenses, wearable sensors for muscular activities, biodegradables hydrogels for reconstructive surgery and many more. All of these classes have been continuous studies with time to improve the efficiency and filed of applications. Beside all these applications, recently hydrogels were used for tissue engineering especially as a scaffold for stem cells. It was found that hydrogels play an important role in brain application including the treatment of brain tumors. This review covers the use of hydrogels in brain applications.
