  • Detection method using nanoaggregate-embedded beads and system thereof
    Patent number: 8187820
    Abstract: The invention discloses a detection method using nanoaggregate-embedded beads and system thereof, which are characterized in that the nanoaggregate of Raman dye and metal nanoparticles is coated by an inorganic oxide to form a nanoaggregate-embedded bead, and which is then conjugated with a probe molecule to form a sensor bead. The Raman spectra of the product formed by binding of the sensor bead and an analyte in a sample is detected for determining whether the analyte exists in the sample. In embodiment, the pH of the solution of metal nanoparticles is controlled to keep at 10, and the concentration of the Raman dye is controlled to keep between 1×10?6 M and 2×10?6 M for reducing the size of the nanoaggregate.
