Selective surface modification method for microfluidic chip channel and microfluidic chip for double emulsion thereby

摘要

The present invention provides methods and this selective surface modification using a double emulsion prepared for the manufacture of microfluidic chip channel relates to a microfluidic chip, and more particularly, (A) trialkoxy silyl alkyl methacrylate solution to fill the heating step of modifying the surface so as to have a hydrophobic surface to the channel of the microfluidic chip; And (B) the (A) surface-modified hydrophilic surface of the microfluidic channel to the desired filling the acrylic acid solution containing a photoinitiator to only that area of the chip comprising surface-modified to have a hydrophilic surface by photopolymerization by irradiation with ultraviolet rays in the step ; relates to a surface modification method of the microfluidic chip channel, characterized in that said Can be selectively controlled wetting (wettability) of the channel of the microfluidic chip to a more simple and mild conditions according to the method of the present invention, it is possible to modify the surface structure so as to have a more stable surface, double emulsion, further a multi- the emulsion can be produced efficiently, as well as to control the droplet size and structure to facilitate the individual. ;
