TLDR
Three-dimensional porous structures fabricated with an SU-8 photoresist using a 3D laser lithography system for targeted cell transportation and human embryonic kidney 239 cells are cultivated in the microrobot.Abstract:
Magnetically manipulated microrobots are demonstrated for targeted cell transportation. Full three-dimensional (3D) porous structures are fabricated with an SU-8 photoresist using a 3D laser lithography system. Nickel and titanium are deposited as a magnetic material and biocompatible material, respectively. The fabricated microrobots are controlled in the fluid by external magnetic fields. Human embryonic kidney 239 (HEK 239) cells are cultivated in the microrobot to show the possibility for targeted cell transportation.read more

Daniel Mazia,Gerald Schatten +1 more
TL;DR: The attachment of cells to the polylysine-treated surfaces can be exploited for a variety of experimental manipulations and is found to be the case for nuclei isolated from sea urchin embryos and for the microtubules of flagella, which are well displayed after the membrane has been disrupted by Triton X-100.
