Optical sensor technologies measurands and sensor categories at this point in the evolution of optical sensing technology, one can measure nearly all of the physical measurands of interest and a very large number of chemical quantities. Development of an ion-sensor using fluorescence resonance energy transfer dibyendu dey, jaba saha, d bhattacharjee, syed arshad hussain dna sensor  and hard water sensor  based on the fret between acf and rhb in the present communication we tried to investigate the effect of k+, na+, mg2+. Abstract a method is presented for the sensing of water hardness by determining the concentration of calcium and magnesium in water, based on fluorescence resonance energy transfer (fret) process.
Results at an in-use dilution of 1%, the test cleanser reduced free ca 2+ from ~500 ppm to 200 ppm a 10% in-use dilution bound virtually all free ca 2+the anionic surfactant component contributed the most to this effect in the exploratory in vivo study, we measured a reduction of ~15% in free ca 2+ from simulated hard water over 10 minutes. Fluorescence analysis after pre-column fmoc derivati- zation for direct determination of glyphosate and ampa in water samples at the 010 µg/l level that is suitable for. The fluorescence resonance energy transfer (fret) phenomenon may be very effective tool for the designing of hard water sensors based on the fret between two laser dyes here we demonstrated a hard water sensor. Sulfur doped fluorescent carbon dots as nanosensors for rapid and sensitive monitoring of calcium in hard water herein, we have developed carbon nanodots (c-dots) doped with sulfur as fluorescent nanosensor for rapid and sensitive determination of dissolved calcium ion concentrations and water hardness in natural aqueous media.
The use of fluorescence resonance energy transfer has enabled the sensor to gain some of the advantages of lifetime-based sensor technology, and to be interrogated using a low-cost phase fluorometric measurement technique. Water softeners hard water is any water supply that contains excess minerals or metals, such as calcium and magnesium although hard water is generally safe to use, it can cause a variety of problems related to cleaning and appliance life and efficiency.
