A biosensor cartridge includes a plasma separator, a plasma metering chamber, a mixer, and a biosensor.

Biosensor cartridge

Provided is a method for amplifying a frequency variation of a detected signal in a biosensor that is used for detecting a biomolecule by measuring a change in frequency of an oscillating signal, the change being caused by pressure a biomolecule applies to a piezoelectric substance. The method for amplifying a frequency variation of a detected signal comprises the steps of: (a) applying a sample to a probe being fixed to an upper portion of a substrate of the biosensor to allow a biomolecule in the sample to be bound to the probe; (b) applying protein tagged with a metal particle to the biosensor to allow the protein and the biomolecule to be bound with each other; and (c) applying a metal enhancer to the biosensor to allow the metal enhancer to be bound to the metal particle having been bound to the protein.
