Artificial organs, hydrogel polymers

In order to construct artificial organs with an excellent function similar to the real biological organ, material innovation is urgently required, i.e., one should find a man-made soft and wet material as substitute for biotissue. Synthetic hydrogels, which consist of polymer networks swollen with large amounts of water (the same as biotissue), are the only candidates [5]. Different from biotissue, tlie water content...
