The present invention is a method for a biochip detecting limited cells. The present invention comprises steps of: obtaining a nylon membrane chip having required nucleotide fragments arranged in a dot matrix way by using a manual spotter; naturally drying by heat and fixing the nucleotide fragments on the nylon membrane chip by a rapid nucleic acid cross-linker when preparing a chip; collecting some normal whole blood to be linearly amplified; synthesizing required amount of cDNA by a reverse transcription to obtain a marker as a probe; processing labeling, hybridization and post-hybridization to the chip and the marker; processing chemical color reaction; and automatically analyzing the result image after the chemical color reaction. Accordingly, a gene biochip operation technology platform with low cost, easy operation and high efficiency is obtained. And so the functions and the applications of the gene biochip can be effectively worked out and the practical applications of the gene biochip on related fields can be conclusively popularized.
