New supramolecular alzheimer’s drugs

New supramolecular alzheimers drugs | Chemistry World - Supramolecular chemistry could provide a new avenue in the treatment of Alzheimer’s disease, say scientists in China. The group demonstrates for the first time that supramolecular complexes can inhibit the aggregation of a peptide thought to cause Alzheimer’s disease.

Massive stellar bond

New type of bond predicted around massive stars | Chemistry World - Researchers have described a new type of chemical bond distinct from the two classic modes of atomic bonding – ionic and covalent. The new bonding, predicted by complex quantum mechanical computations, occurs only in hugely powerful magnetic fields – tens of thousands of times greater than can be generated in the laboratory. Such strong magnetic fields are not fanciful, however. They exist in the vicinity of certain types of rotating stars, such as white dwarfs.

pH sensor gets under your skin

pH sensor for use in the body - US scientists have developed a pH sensor based on nanocrystal quantum dots designed to be used in a biological pH range. pH is an important factor in monitoring tumour health and the efficacy of anticancer treatments, and the sensor could be injected into tumours to monitor their health in real time.
