(a)-(d): Optical micrographs of the 20-hour-cultivation of hippocampal cells on the collagen coated microchips. (a) without any additional treatment; (b) after 65°C, 1 h treatment; (c) after 90°C, 1 h treatment; (d) without collagen coat (as a reference). (e), (f): Optical micrographs of cultivated cells in AMCAs. (e) cells cultivated in the photo-thermal etched microchambers without any additional treatment; (f) cultivated in the collagen re-coated microchambers after photo-thermal etching.
