HOT Article: Luminescent drug delivery of ibuprofen

In this Dalton Transactions Hot article, calcium silicate microparticles doped with rare earth ions were loaded with ibuprofen and tested for their drug delivery properties.

The microparticles showed strong luminescence, which increased as the ibuprofen was released, allowing the drug delivery to be monitored, a highly useful property in therapeutics.

HOT Article: Kinetics of beta-hydroxyalkyl rhodium porphyrins to make water soluble catalysts

In this Dalton Transactions Hot article, the kinetics of rhodium porphyrin b-hydroxy alkyl reactions in water and DMSO are investigated.

Understanding the mechanics of these types of reaction will lead to better selectivity in catalytic oxidation of alkenes and, as the authors say,  ‘may lead to the development of water soluble catalysts’. These can then be used to produce a green form of oxidation chemistry.

HOT Article: Fluorescent sensor for pyrophosphate

In this Dalton Transactions Hot article, researchers at Nanjing University, China have developed a fluorescent sensor to detect the biologically important anion pyrophosphate.

Pyrophosphate in the body is integral to the production of ATP and DNA, and is involved in preventing the formation of hydroxyapatite in extracellular fluid. A lack of pyrophosphate leads to medial calcification, while an excess has been linked to calcium pyrophosphate dihydrate deposition disease, a form of rheumatism.

In this paper the authors make a ratiometric fluorescent sensor using a naphthalene appended tetraazamacrocycle (1)-Zn2+ complex. The sensor is not influenced by its environment, as the ratio of fluorescent intensities at two different wavelengths is measured, rather than using one lone fluorescence, as in the conventional method.

READ FOR FREE until January 20th.

Hot Article: Convenient entry into imido metal chemistry

Jörg Sundermeyer and co-workers at the Philipps-Universität Marburg in Germany have delve into the world of imido metal chemistry in their recent Dalton Transactions Hot Article. The team have found a useful way to make imido complexes by exchanging terminal metal oxo functionalities with N-organo and N-sulfonylimidos via metathesis using bent, thus very reactive sulfinyl amines R-NSO and sulfinyl sulfonylamides R-SO2-NSO.

Read their Hot Article now! Free to view until the 20th January!

Hot Article: a benzene absorber cleaning up pollutants!

Shilun Qiu, Guangshan Zhu and co-workers have made a microporous organic-inorganic silsesquioxane-based framework, JUC-Z1, which is an effective absorber of both benzene and water. The team used a Yamamoto-type of Ullmann cross-coupling reaction to make the framework. ‘Its ability to selectively adsorb benzene makes JUC-Z1 greatly promising for applications dealing with environmental aromatic pollutant problems,’ say Qiu and Zhu.
