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

26.10.2012
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: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

A boost for graphene-based light detectors

Light detection and control lies at the heart of many modern device applications, such as smartphone cameras. Using graphene as a light-sensitive material for...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
