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.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
