The paper shows an approach to the determination of pH changes of solutions with a fine spatial resolution by means of fiber-optic tapers and fluorescence detection. This approach can be adopted for the determination of auxin flow through celluar membranes. Spectral absorption and fluorescence of pH transducers, namely of fluorescein, carboxyfluorescein, 6,8-dihydroxy-1,3-pyrenedisulfonic acid disodium salt and 2',7'-bis(2-carbonylethyl)-5(6)-carboxyfluorescein, were tested. The approach, based… Expand
Fiber-optic pH detection in small volumes of biosamples
TLDR
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 and the results were validated by comparison with conventional electrochemical pH measurements. Expand
Local real-time detection of pH using fibre tapers
A size of tapered silica fibre probes makes them suitable for exploration of small objects, as e.g. cells. Fibre-optic probes of enhanced mechanical durability can be advantageously used particularlyExpand
Optical sensor based on sensitive polymer layer
In chemical, oil, and food industries, there are still higher requirements on miniaturization of optical sensors for a concentration measurement of gases e.g. a CO2, O2, and NH3. The paper deals withExpand
Tapered optical fibres for sensing

Analytical properties and sensor size effects of a micrometer-sized optical fiber glucose biosensor.
TLDR
A micrometer-sized fiber-optic fluorescence biosensor for glucose has been fabricated, based on the enzymatic reaction of glucose oxidase that catalyzes the oxidation of glucose to gluconic acid and hydrogen peroxide while consuming oxygen. Expand
Development of a submicrometer optical fiber oxygen sensor.
TLDR
A submicrometer optical fiber oxygen sensor has been fabricated, based on the fluorescence quenching of tris-(1,10-phenanthroline)ruthenium(II) chloride in the presence of oxygen or dissolved oxygen, which is an improvement by a factor of 10(6) as compared to other existing optical Fiber oxygen sensors.

PIN Proteins Perform a Rate-Limiting Function in Cellular Auxin Efflux
TLDR
Conditional gain-of-function alleles and quantitative measurements of auxin accumulation revealed that the action of PINs in auxin efflux is distinct from PGP, rate-limiting, specific to auxins, and sensitive to auxin transport inhibitors, which suggests a direct involvement ofPINs in catalyzing cellular auxIn efflux. Expand
Auxin inhibits endocytosis and promotes its own efflux from cells
TLDR
The data imply a previously undescribed mode of plant hormone action: by modulating PIN protein trafficking, auxin regulates PIN abundance and activity at the cell surface, providing a mechanism for the feedback regulation of auxin transport. Expand
