The invention discloses a biological molecule detection method based on silica nanoparticles as a solid-phase carrier, and the method is characterized in that: by hydrophilic adsorption or chemical action, a flat tube can uniformly absorb silica nanoparticles on the bottom of the flat tube, so that the bottom of the flat tube shows color for distinguishing different detection objects, after treatment of the silica nanoparticles as the solid-phase carrier, the adsorption capacity is enhanced, the surface is uneven, the specific surface area is increased for connecting more probes, and the detection sensitivity is significantly improved, and the detection time is saved. |
