Apparatuses, systems, and methods are disclosed for transportation and detection of analytes. Beads (624) may be functionalized with a capture moiety (626) to bind to a target moiety. Beads (624) that have not been incubated in a sample solution (110) may be positioned in a fluid (414), near a sensing surface (420) for a biosensor (104). A calibration measurement may be performed using the biosensor (104), after which the beads (624) may be removed. Beads (624) that have been incubated in the sample solution (110) may be positioned near the sensing surface (420), and a detection measurement may be performed using the biosensor (104). A parameter such as the presence, absence, or concentration of the target moiety in the sample solution (110) may be determined based on the calibration measurement and the detection measurement. |
