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: Increasingly severe disturbances weaken world's temperate forests

Longer, more severe, and hotter droughts and a myriad of other threats, including diseases and more extensive and severe wildfires, are threatening to transform some of the world's temperate forests, a new study published in Science has found. Without informed management, some forests could convert to shrublands or grasslands within the coming decades.

"While we have been trying to manage for resilience of 20th century conditions, we realize now that we must prepare for transformations and attempt to ease...

Im Focus: OU astrophysicist and collaborators find supermassive black holes in quasar nearest Earth

A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.

The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...

Im Focus: What would a tsunami in the Mediterranean look like?

A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).

Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...

Im Focus: Self-healing landscape: landslides after earthquake

In mountainous regions earthquakes often cause strong landslides, which can be exacerbated by heavy rain. However, after an initial increase, the frequency of these mass wasting events, often enormous and dangerous, declines, in fact independently of meteorological events and aftershocks.

These new findings are presented by a German-Franco-Japanese team of geoscientists in the current issue of the journal Geology, under the lead of the GFZ...

Im Focus: FIC Proteins Send Bacteria Into Hibernation

Bacteria do not cease to amaze us with their survival strategies. A research team from the University of Basel's Biozentrum has now discovered how bacteria enter a sleep mode using a so-called FIC toxin. In the current issue of “Cell Reports”, the scientists describe the mechanism of action and also explain why their discovery provides new insights into the evolution of pathogens.

For many poisons there are antidotes which neutralize their toxic effect. Toxin-antitoxin systems in bacteria work in a similar manner: As long as a cell...
