a Real-time measurement of l-alanine adsorption on silver-GST substrate. b The linear fitting of sensor response after 10 minutes of l-alanine adsorption. c The real-time adsorption measurement of biotin in PBS. d The linear fitting of sensor response after 20 min of biotin adsorption. These sensorgrams were acquired with 785 nm excitation. The error bar denotes the variation of GH shift measured at the last minute of adsorption measurement
