Beadstar Bio's magnetic fluorescent encoded microspheres play a key role in this technology. As the carrier for RAA amplification, they combine high-efficiency magnetic separation and precise fluorescent encoding capabilities, enabling rapid screening of multiple foodborne pathogenic bacteria in a single test.

(1) High Sensitivity: Combined with Beadstar Bio's magnetic fluorescent encoded microspheres, the RAA technology achieves a limit of detection (LOD) as low as 0.8 femtomolar (fM), with a linear detection range from 0.8 fM to 80 picomolar (pM) covering five orders of magnitude. This high sensitivity benefits from the low background noise and strong detection signals of the magnetic fluorescent encoded microspheres.
(2) Rapid and Easy Operation: Compared with traditional qPCR technology, the SC-RAA assay requires no complex thermal cycling equipment, and the entire detection process takes only about 30 minutes. Beadstar Bio's magnetic fluorescent encoded microspheres support rapid magnetic separation, further simplifying the operational workflow.
(3) Multiplex Detection Capability: The SC-RAA technology can simultaneously detect multiple foodborne pathogens, breaking through the limitations of traditional multiplex detection methods. Through distinct fluorescent encoding, Beadstar Bio's magnetic fluorescent encoded microspheres enable the concurrent detection of various pathogens.
