Summary of "Reply to Comment on "Hypersensitive Luminescence of Eu3+ in Dimethyl Sulfoxide As a New Probing for Water Measurement""
Luminescence of rare earth ions in dimethyl sulfoxide (DMSO) has been recently observed and reported by our group.1, 2 Potentially, luminescence of rare earth/DMSO compounds has many applications including the probing of trace water in organic solvents like DMSO. The measurement based on the relative intensity changes in two peaks is more reliable and selective than using the intensity change of only one emission peak. Both measurements based on intensity and lifetime changes have advantages and disadvantages. Techniques based on luminescence intensity changes are easy, fast, convenient and cost-effective. Decay lifetime-based measurement is complimentary to intensity-based detection; however, it will likely never replace intensity-based techniques for practical applications.

Medical and Biotech [MESH] Definitions
Dimethyl Sulfoxide
A highly polar organic liquid, that is used widely as a chemical solvent. Because of its ability to penetrate biological membranes, it is used as a vehicle for topical application of pharmaceuticals. It is also used to protect tissue during CRYOPRESERVATION. Dimethyl sulfoxide shows a range of pharmacological activity including analgesia and anti-inflammation.
Water Movements
The flow of water in enviromental bodies of water such as rivers, oceans, water supplies, aquariums, etc. It includes currents, tides, and waves.
Byssinosis
A condition of BRONCHOCONSTRICTION resulting from hypersensitive reaction to inhaled dust during the initial processing of cotton, flax, or hemp in the textile industry. Symptoms include wheezing and tightness in the chest.
Water Pollutants
Substances or organisms which pollute the water or bodies of water. Use for water pollutants in general or those for which there is no specific heading.
Water Purification
Any of several processes in which undesirable impurities in water are removed or neutralized; for example, chlorination, filtration, primary treatment, ion exchange, and distillation. It includes treatment of waste water to provide potable and hygiene water in a controlled or closed environment as well as provision of public drinking water supplies.
