“…The development of refractive index and substance concentration sensor has been done with various methods and configurations. Reflection method using mirror (flat or concave) has been used to detect the refractive index of the liquid, calcium concentration, sodium chloride, glucose, rhodamine B, and magnesium using fiber bundle or fiber coupler as the sensor probe. The working mechanism of the refractive index and substance concentration sensor is based on displacement sensor, that is, by shifting the sensor probe against the mirror with the solution being made as a medium between sensor probe and mirror.…”

Non‐touch detection of rhodamine B concentration in distilled water using fiber coupler and concave mirror (CM) successfully demonstrated. Based on displacement sensor, the concentration of rhodamine B is detected through the peak voltage value which is resulted from the displacement profile. Using the He‐Ne (543 nm) laser as the source, the fiber coupler as the sensor probe and CM with the curvature radius of 12 mm as the reflector as well as the sample container, the rhodamine B concentration can be detected in the range 0‐20 ppm and the resolution of 0.26 ppm.

“…Synthetic lectins have potential (1) as models for natural lectins, in mechanistic and other fundamental studies, (2) as complementary alternatives to natural lectins in glycobiological research, (3) as diagnostic tools in medicine, and (4) as pharmaceuticals, based on the disruption of natural carbohydrate recognition. A particular medium-term objective is the monitoring of glucose levels in diabetics [28][29][30][31][32][33]. Although current enzyme-based methods are inexpensive and effective, they are not welladapted to continuous operation over long periods (as required, for example, in an ''artificial pancreas'').…”

The importance of carbohydrate recognition in biology, and the unusual challenges involved, have lead to great interest in mimicking saccharide-binding proteins such as lectins. In this review, we discuss the design of artificial carbohydrate receptors, focusing on those which work under natural (i.e. aqueous) conditions. The problem is intrinsically difficult because of the similarity between substrate (carbohydrate) and solvent (water) and, accordingly, progress has been slow. However, recent developments suggest that solutions can be found. In particular, the "temple" family of carbohydrate receptors show good affinities and excellent selectivities for certain all-equatorial substrates. One example is selective for O-linked beta-N-acetylglucosamine (GlcNAc, as in the O-GlcNAc protein modification), while another is specific for beta-cellobiosyl and closely related disaccharides. Both show roughly millimolar affinities, matching the strength of some lectin-carbohydrate interactions.

“…The curve amplitudes become different for samples with different refractive indices [2], so that the sensor can be used as a refractometer. Since the refractive index changes with the relative concentration in composite samples (e.g., solutions), then the signal dependence on the refractive index can be used for concentration measurements, as reported elsewhere [3]. However, when the dependence of the refractive index on the concentration is small, as in the case of the methylene blue-water samples at micromolar concentrations, then the signal changes are too weak to be detected.…”

“…Of particular interest are sensors for biomedical, food industry and environmental applications. Optical fiber sensors have been designed for measurement of distance, displacement and vibration [1], but similar devices have been also used as reflection refractometers [2] that are suitable also for concentration measurement in solutions [2,3]. In the present work, we propose a variation of the optical fiber refractometer where changes of the refractive index in the sample area that is trespassed by the probe beam sent and collected via the fiber tip are generated through the photothermal (PT) effect induced by a pump laser beam, in particular the so-called thermal lens (TL) effect.…”
