| 1. A surface plasmon resonance (SPR) detecting apparatus, comprising:
a detection chip, having a metal film, wherein the metal film has an SPR characteristic and at least one detection area; and
a fluid driving chip, having a droplet control device, wherein the droplet control device comprises at least one first electrode
and at least one second electrode, and the first electrodes are separated from the second electrodes;
wherein a space for a droplet to pass through is formed between the metal film and the fluid driving chip, and a relative
voltage is provided between the first electrodes and the second electrodes, so as to drive the droplet in the space.
