The present invention relates to a biomaterial measuring system and method capable of precisely measuring the presence and amount of bio-elements such as proteins and genes in the air or the gaseous atmosphere having controlled temperature and humidity. In one embodiment, a method for measuring a biomaterial includes preparing a cantilever sensor having a plurality of cantilevers, measuring a reference resonance frequency for the plurality of cantilevers, and measuring the plurality of biomaterials in a sample. Reacting the cantilever, measuring a resonant frequency of the cantilever after the reaction in a closed system isolated from the external environment and controlled to a specific state of temperature and humidity, and changing the resonant frequency of the cantilever before and after the reaction. Calculating a value and performing a quantitative analysis of the biological material contained in the sample. It characterized.n n n n Cantilever, biomaterial, PSA, resonant frequency |
