Now researchers developing novel programmable materials, With the help of DNA, the smallest particles of silicon dioxide and carbon nanotubes, researchers have now developed new materials that can be programmed.

And these nanocomposites can be designed for different applications and are programmed in such a way that they can be decomposed quickly and gently. For medical applications, they can create environments where human stem cells can grow and develop. now the researchers are developing novel programmable materials.

Stem cells are cultivated for basic research and the development of effective therapies for serious diseases, that is for example to replace damaged tissue. However, stem cells only form healthy tissue in a suitable environment. For the formation of three-dimensional tissue structures, materials that support cell function with perfect elasticity are needed.

New programmable materials are now being developed that are suitable as substrates for biomedical applications. These materials can be used, among other things, to create an environment where human stem cells can be stored and developed.

These composites are produced by biochemical reactions and their properties can be adjusted by varying the amount of each component. In addition, nanocomposites can be programmed to break down and release cells that grow internally quickly and easily. This can then be used for additional experiments.

The use of living microorganisms in electrochemical devices is a growing field of research, according to researchers. In this way, microbial fuel cells, microbial biosensors or microbial bioreactors can be produced.

This is exoelectrogenic, which means that when organic matter decomposes without oxygen, an electric current is generated. When Shewanella oneidensis is cultivated in developed nanocomposites, it fills a composite matrix, while the non-exoelectrogenic bacteria Escherichia coli remains on its surface.

The composition containing Shewanella remained stable for several days. Future work will focus on opening new applications for bioengineering new ingredients.
