Silica-based Photopigments - Silica-based gel with entrapped (photo-)sensitive material

30.10.2012
Entrapping sensitive material, e.g. immobilization of biomolecules or immobilization of other light-, pH- and/or temperature sensitive material is a demanding task in the art. That is, immobilization of biomolecules within polymer matrices has gained considerable importance in various fields of biotechnical processes.

For example photosynthetically active components which can absorb light and transfer energy, may be immobilized (entrapped) within suitable immobilization compounds, like polymer matrices for biotechnical processes. However, photosynthetically active components are extremely unstable and need to be stabilised outside of the cell, in order to use these highly effective components e.g. in third generation photo¬voltaics and artificial photosynthesis, respectively.

The immobilized sensitive material includes active components, like the mentioned photosynthetically active components, but also optically and electrochemically active material. Beside encapsulation of whole cells, cell compartments or cell organelles as well as biological macromolecules including proteins, enzymes or other sensitive materials have been entrapped or encapsulated. In addition, systems have been described wherein the sensitive materials have been encapsulated in biopolymers first and said encapsulated sensitive materials are coated with e.g. silica allowing to associate soft biocompatible components, like alginate, with a tough thermostable non-swelling component like silica. The present invention describes new transparent silica-based gel and “glass” with entrapped sensitive material which is in particular light-, pH- and/or temperature- sensitive and furthermore a method of its preparation.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
