Abstract
Present invention describes a cartridge for analyzing target analytes in biological compound, low molecular weight compound, or other samples and an analysis method using the cartridge. In more detail, the present invention describes a fabrication method of a cartridge to measure, based on localized surface plasmon resonance (LSPR) phenomenon, changes in absorbance values or maximum absorption wavelength values, which are caused by changes in effective refractive index due to the reactivity difference between biological compounds or low molecular weight compounds on the metal nanoparticle immobilized surface, and a sample analysis method.
Claims27
A cartridge utilizing a localized surface plasmon resonance phenomenon, the cartridge for analyzing samples comprising:
- a sample injection part for introducing a target analyte sample or a receptor molecule sample into;
- a sample channel connecting the sample injection part and a measurement part for feeding the target analyte sample or the receptor molecule sample into the measurement part;
- and
- a measurement part comprising target analysis materials immobilized on a thin film layer of surface plasmon resonance(SPR)-active materials immobilized on a substrate.
