Abstract
A method for detecting biomaterial by means of a dye having a linear upconversion fluorescent property is provided. The method includes the steps of: i) preparing a fluorophore having a linear upconversion fluorescent property; ii) reacting the fluorophore and biomaterial to obtain a reaction complex thereof; iii) exciting the reaction complex by means of a light source having a longer wavelength than the maximum light-emitting wavelength of the fluorophore; and iv) detecting and measuring the light-emitting signal having a shorter wavelength than the wavelength of the excited light emitted from the excited reaction complex. A system and a kit for detecting biomaterial using a dye having a linear upconversion fluorescent property are also provided.
