Abstract

The invention discloses a stereo micro-fluidic chip, comprising a first substrate, a second substrate, ..., and an N substrate, wherein the first to N substrates are provided with micro-fluidic channels or micro-fluidic chambers and successively and mutually connected via polymer layers, which enables the micro-fluidic channels or micro-fluidic chambers of the first to N substrates to be communicated, so a stereo micro-fluidic structure is formed. The invention also discloses a preparation method for the micro-fluidic chip. The preparation method comprises the following steps: uniformly coating the substrates with a prefabricated polymer and carrying out drying so as to obtain the polymer layers with sizes of 1 [mu]m to 100 [mu]m; and separately bonding the first substrate and the second substrate with one of the polymer layers and carrying out repeated lamination so as to obtain the micro-fluidic chip. Thus, bonding of the micro-fluidic chip is realized without application of pressure; and the method is simple and can be extensively used for preparation of the micro-fluidic chip.
