| An array platform for three-dimensional cell culturing and drug testing and  screening is disclosed.  In the array platform, a hydrogel-cell mixture injection area is  configured to inject a plurality of kinds of hydrogel-cell mixtures.  Cell observation   areas  are  connected  to  the  hydrogel-cell  mixture  injection  area.    Electrodes  are  disposed under the cell observation areas and automatic cell quantification and three- dimensional cell co-arrangement of the plurality of kinds of hydrogel-cell mixtures in the cell observation areas through the electrodes to imitate a structure of body’s  tissues.  A drug injection area is configured to inject a plurality of kinds of drugs. Drug combination generators respectively correspond to the cell observation areas  and are connected to the drug injection area.  Each drug combination generator has a  microfluidic  channel  structure  and  configured  to  generate  drug  combinations  according to the plurality of kinds of drugs. |
