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: Smarter window materials can control light and energy

Researchers in the Cockrell School of Engineering at The University of Texas at Austin are one step closer to delivering smart windows with a new level of energy efficiency, engineering materials that allow windows to reveal light without transferring heat and, conversely, to block light while allowing heat transmission, as described in two new research papers.

By allowing indoor occupants to more precisely control the energy and sunlight passing through a window, the new materials could significantly reduce costs for...

Im Focus: Simulations lead to design of near-frictionless material

Argonne scientists used Mira to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. Argonne Leadership Computing Facility (ALCF) researchers helped enable the groundbreaking simulations by overcoming a performance bottleneck that doubled the speed of the team's code.

While reviewing the simulation results of a promising new lubricant material, Argonne researcher Sanket Deshmukh stumbled upon a phenomenon that had never been...

Im Focus: NASA satellite camera provides 'EPIC' view of Earth

A NASA camera on the Deep Space Climate Observatory (DSCOVR) satellite has returned its first view of the entire sunlit side of Earth from one million miles away.

The color images of Earth from NASA's Earth Polychromatic Imaging Camera (EPIC) are generated by combining three separate images to create a...
