The design of fluorescent sensors is of major importance because of the high demand in analytical chemistry, clinical biochemistry, medicine, the environment, etc. Numerous chemical and biochemical analytes can be detected by fluorescence methods cations (H+, Li+, Na+, K+, Ca2+, Mg2+, Zn2+, Pb2+, Al3+, Cd2+, etc.), anions (halide ions, citrates, carboxylates, phosphates, ATP, etc.), neutral molecules (sugars, e.g. glucose, etc.) and gases (O2, CO2, NO, etc.). There is already a wide choice of fluorescent molecular sensors for particular applications and many of them are commercially available. However, there is still a need for sensors with improved selectivity and minimum perturbation of the microenvironment to be probed. Moreover, there is the potential for progress in the development of fluorescent sensors for biochemical analytes (amino acids, coenzymes, carbohydrates, nucleosides, nucleotides, etc.).

From 1878 to 1883 Nilson served as professor of analytical chemistry at the University of Upsala, but in his later years he taught at the Agricultural Academy at Stockholm. He found that the sterility of the calcareous moors of his native island was caused by lack of potash. After liberal use of kainite fertilizer, recommended by Nilson, Gothland Island began to yield good crops of sugar beets (6).

Spectrophotometry is any technique that uses light to measure chemical concentrations. A procedure based on absorption of visible light is called colorimetry. The most-cited article in the journal Analytical Chemistry from 1945 to 1999 describes a colorimetric method by which biochemists measure sugars.4... 

Invertase (EC 3.2.1.26) catalyzes the hydrolysis of P-fructofuranosides and has been used in analytical chemistry (biosensors), in confectionary, and in the production of inverted syrup (1). Invert sugar syrup, which can be obtained by acid or enzymatic hydrolysis of sucrose, is a valuable commercial product especially in countries where the main sources of sugar are beet or cane. With acid hydrolysis, the final syrup is often contaminated with colored oxidation compounds, which arise from cyclization of hex-oses at low pH and high temperatures (2-4). Such a problem does not occur... 

Use Water conditioning (softening and complete deionization), recovery and concentration of metals, antibiotics, vitamins, organic bases, catalysis, de-colorization of sugar, manufacture of chemicals, neutralization of acid mine-water drainage, analytical chemistry, water treatment in nuclear reactors, pharmaceuticals. 

Use Analytical chemistry (reagent for detecting aldehydes, sugars, etc.), organic synthesis (intermediates, dyestuffs, pharmaceuticals). The hydrochloride is a strong reducing agent.

Via a magneto-optic effect, the (-)-form of an optical isomer rotates the plane of polarization of a beam of polarized light that passes through a quantity of the material in solution counterclockwise, the (+)-form clockwise. It is due to this property that it was discovered and from which it derives the name optical activity. The property was first observed by J.-B. Biot in 1815, and gained considerable importance in the sugar iiidustrx. analytical chemistry, and pharmaceuticals. 

Some of these reactions are essentially quantitative and are even used in analytical chemistry (e.g. benzal of pentaerithritol)3) or to introduce protective groups in the synthesis of nucleic acids or sugars (reactions of hydroxyl groups at adjacent carbon atoms in sugar with acetone or benzaldehyde)4).

The electrical industry is one of the greatest users of copper. Copper s alloys, brass and bronze, are important all American coins are copper alloys, and gun metals also contain copper. Copper has wide use as an agricultural poison and as an algicide in water purification. Copper compounds, such as Fehling s solution, are widely used in analytical chemistry tests for sugar.

Marggraf, Andreas Sigismund (1709—1782) German chemist and pioneer of analytical chemistry from Berlin in 1747 he announced his discovery of sugar in beets and devised a method nsing alcohol to extract it.
