Abstract
Official abstract text for this publication.
A micro fluidic device comprises one microstructure layer ( 5 ) and one cover layer ( 1 ), wherein the cover layer ( 1 ) is connected to the microstructure layer ( 5 ). The microstructure layer ( 5 ) comprises one bottom layer and a plurality of microstructures on it to position samples. The cover layer ( 1 ) comprises one top layer, one positioning well ( 6 ) and at least one inlet pool ( 4 ). The positioning well ( 6 ) is right above the microstructures and connected with each other. The inlet pools ( 4 ) and the positioning well ( 6 ) are connected by microchannels ( 3 ) which are formed between the microstructure layer ( 5 ) and the cover layer ( 1 ). The micro fluidic device can be applied in vitro fertilization, in determining how glial cells affect neurons, in constructing neural network and in detecting cell growth conditions.
