摘要	The response of optical fiber surface plasmon resonance (SPR) sensor to potential is monitored in real time. The potential-induced reflectance of a gold-coated optical fiber SPR probe is dependent on potential step width and ionic strength. Wider potential step and stronger ionic strength are generally able to enhance the reflectance and accelerate the response time. The specifically adsorptive anion Cl- provides a pronounced effect on a potential-dependent SPR probe. The exclusive contact of the SPR probe with anion Cl- could significantly slow down the optical response. The work offers opportunities for optical fiber SPR probes to characterize the electrochemical application.
