BIOCHIP AND METHOD OF INJECTING SPECIFIC MICRO VOLUME OF SAMPLE USING THE SAME

摘要

PURPOSE: A biochip and a method for quantitatively injecting a specimen using the same are provided to apply a simple fluid channel structure in the biochip without a complicated pumping control device. CONSTITUTION: A biochip(100) includes a reaction chamber(114), an injection channel(112), and a discharging channel(116). The reaction chamber includes a reagent for detecting a specimen. The injection channel includes a specimen injection channel(112i) and a specimen bypass channel(112d). The discharging channel is in connection with a specimen discharging channel(112o) and the specimen bypass channel. A method for quantitatively injecting a specimen includes the following steps of: injecting and bypassing a specimen through the specimen injection channel and the specimen bypass channel, respectively; blocking the specimen discharging channel in connection with the reaction chamber by the specimen transferred through the specimen bypass channel; and discharging excessive specimens through the specimen bypass channel by air.
