Xi'an Jiaotong Team Uses Inkjet-Printed Conductive Patterns to Align Neural Cells
Researchers at the Second Affiliated Hospital of Xi'an Jiaotong University in northwestern China and the Key Laboratory of Biomedical Information Engineering of the Ministry of Education have built an in vitro screening platform combining electrospun PLCL with inkjet-printed reduced graphene oxide (rGO) and growth-factor micropatterns. Because it varies conductive, biochemical and topographical cues together, the platform can evaluate printing parameters and electric-field strength in a single system. Under 150 mV/cm direct-current stimulation, PC-12 cells showed more neurite-like outgrowth and better alignment than with no stimulation or at 300 mV/cm.
