Annotation	The paper deals with the fiber-optic detection of the pH values of droplets of plant xylem exudate based on fluorescence intensity measurements. For this purpose, novel V-taper sensing probes with a minimum diameter of around 8 μm were prepared that enable the delivery of fluorescence signal from the detection site on the taper tip to the detector. The taper tips were coated with pH-sensitive HPTS and a reference Ru-phen dichloride immobilized in a xerogel layer. Using the developed V-taper sensing probes, the pH values of in vivo and in vitro samples of small volumes (6 μl) of exudate were measured.
