It works by growing separate cultures of individual cell types , and then spraying them out , layer by layer , in combination with a binding agent called a hydrogel , to build up the correct shape .
To solve these problems , four new technologies are used , including the selective tree-like workover designing technology , the temporary plugging technology using hydrogel , the technology for monitoring gas content in logging process , the technology for developing new type washover tools and software which can optimize washover parameters .
This article discussed the principle of physical cooling and meaning for development of the hydrogel paster . The hydrogel paster shows unique advantage and board application foreground comparing with drug cooling and traditional physical cooling .
A second printing head is used to deposit scaffolding-a sugar-based hydrogel .
第二个打印头用于沉淀支架----一种糖类的水凝胶。
Of course , that only makes sense for the particular hydrogel the team has in the lab now .
当然,独特的水凝胶已被研究团队在实验室做出来,这才有意义。
For tubular structures , such as blood vessels , the hydrogel is printed in the centre and around the outside of the ring of each cross-section before the cells are added .
