Micro-liquid phase reaction method based on substrate with hydrophilic-hydrophobic patterned surface
A micro-liquid phase reaction method based on a substrate with a hydrophilic-hydrophobic patterned surface, including the following: applying a liquid phase system containing a hydrotropic substance and/or an amphipathic substance to a hydrophobic smooth plane in a sample-spotting manner to form an array of tiny droplets, subsequently removing the solvent in each droplet to bond the hydrotropic substance and/or amphipathic substance in each droplet to the hydrophobic smooth plane so as to form an array of hydrophilic bonding points, then moving an aqueous phase system or hydrophilic liquid phase system containing more than one reactants over the hydrophobic smooth plane, thereby forming island-like tiny reaction droplets at each hydrophilic bonding point, and finally under the set reaction conditions, reacting the reactants in each tiny reaction droplet. The method allows a parallel processing system for multiple reactions to be implemented under common experiment conditions, and greatly extends the application range thereof.
