Custom built enzyme to replace harsh and hazardous chemicals
Recently a group of researchers at The Department of Chemistry at University of Copenhagen succeeded in producing an artificial enzyme that points the way to enzymes tailor-made for any application.
With their group leader, Professor Mikael Bols, Ph.d. students Jeanette Bjerre and Thomas Hauch Fenger are publishing details of their breakthrough in recognized international ChemBioChem (15/2009) under the title “Cyclodextrin Aldehydes are Oxidase Mimics”Artificial enzymes for unnatural tasks
Oxidizing processes are considered one of the cornerstones of all chemical production. From paint to pharmaceuticals. But traditional oxidizers have a reputation for being dangerously unrefined. That’s why enzymes are desirable and tailor made ones doubly so. For one thing they can be designed to be unbelievably specific. But even more important is their ability to operate under humane conditions, unlike their traditional chemical counterparts, which often need high temperatures, extreme pressure and corrosive surroundings.
As the new enzymes inch closer to the natural reaction-times, they they are bound to become increasingly important for sensitive processes like those of the pharmaceutical industry.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
