Abstract:
1. A microfluidic control apparatus comprising: a microfluidic control chip including: at least one reaction solution storage chamber disposed within the microfluidic control chip, the chamber containing a reaction solution; at least one branch microchannel having a first end that is connected to the reaction solution storage chamber; and a main microchannel connected to a second end of the branch microchannel, wherein a microfluid of a reaction solution flows through the branch microchannel; a sealing elastic plate and sealing tape configured to seal the reaction solution storage chamber, the sealing tape being disposed between the microfluidic control chip and an sealing elastic plate, the sealing tape and elastic plate being adjacent to the storage solution chamber and outside of the microfluidic control chip; a working fluid that is inert relative to the reaction solution and that is in continuous fluid communication with the reaction solution; and at least one control means that includes at least one needle penetrating the sealing elastic plate and the sealing tape and into the solution storage chamber of the microfluidic control chip, and provides the working fluid through the needle to the reaction solution storage chamber to control the flow of the microfluid without mixing with the microfluid.
