1. A device for the detection of an analyte in a droplet of fluid, comprising:

  • a non-porous and hydrophobic solid phase surface configured to receive and maintain the shape of a droplet of fluid;

    a circumferential gutter in said solid phase surface that defines a predetermined continuous pathway; and

    a capture zone located in the gutter;

    wherein said capture zone includes an immobilized binding agent positioned in said capture zone, said gutter configured such that when said droplet is positioned in said gutter and traveling along said pathway, said droplet repeatedly and periodically travels into and out of said capture zone.
