Abstracts
Disclosed is a substrate comprising a base material and a crosslinked material arranged on the base material, wherein the crosslinked material comprises a branched polyalkylene glycol derivative having: three or more polyalkylene glycol groups each having a polymerizable substituent at the terminal; and a linkage group having a valency of 3 or more and capable of binding to the polyalkylene groups. The substrate can be patterned with a high degree of accuracy and can keep the unadhered state of a cell thereon stably for a long term.
