Embodiment Construction
[0110] specific implementation plan
[0111] The first embodiment describes a first prototype of the microdevice of the invention.
[0112] exist Figure 4 In the prototype shown, the structural material used to realize the fluidic channels was the photodefinable polymer SU-8 mechanically bonded to a PMMA substrate that constituted the channel bottom of the device. Due to its high confinement (micrometer scale), verticality of the grown walls [ref2], biocompatibility [ref3], wide thickness range [ref1] and possibility of gluing several successive layers [ref4], the material Very convenient feature for manufacturing devices. according to figure 1 The design of this prototype of the device of the present invention used is manufactured as follows (see Figure 10 ):
[0113] a) depositing and defining a photodefinable polymer layer on the surface of a free-standing substrate (wafer 1),
[0114] b) depositing and defining a photodefinable polymer SU-8 layer on the surface of ...
