The set of instructions for metabolism and autonomous regeneration allows the material to grow on its own. In their paper, the scientists described the metabolism as the system by which "the materials comprising life are synthesized, assembled, dissipated, and decomposed autonomously in a controlled, hierarchical manner using biological processes. To keep going, a living organism must be able to generate new cells, while discarding old ones and waste.

They devised a biomaterial that can arise on its own from nanoscale building blocks. It can arrange itself into polymers first and into mesoscale shapes after. The DNA molecules in the materials were duplicated hundreds of thousands of times, resulting in chains of repeating DNA that were a few millimeters in length. The solution with the reaction was injected into a special microfluidic device that facilitated biosynthesis. This flow washed over the materials, causing DNA to synthesize its own strands.

The material even had its own locomotion, with the front end growing while the tail end was degrading, making it creep forth.

This fact allowed the researchers to have portions of the materials competing against each other. The material that was created lasted for two cycles of synthesis and degradation but the longevity can be extended, think the researchers.

This could lead to more generations of the material, eventually resulting in a "lifelike self-reproducing machines," said Hamada. Next for the material? The engineers are looking at how to get it to react to stimuli and be able to seek out light or food all on its own.

They also want it to be able to avoid harmful stimuli. The U.

Application-specific developments show often that the combination of several analysis techniques is needed to ensure both process control in nanotechnology as well as performance and reliability of new products.

Artificial Materials - ISTE

In this course, we will explain that the digital transformation in materials science and engineering requires and enables more and more the application of algorithms of artificial intelligence, particularly for new platforms, standards and technologies for data processing, data exchange and data analysis in materials and process characterization. Consequently, future tasks of scientists and engineers will include collecting and interpretation of data, in addition to the development and application of advanced techniques for materials analysis.

The course will provide knowledge in the fields of materials characterization, process control and artificial intelligence. After an introduction into materials analysis in the lab and for process monitoring as well as into artificial intelligence, advanced techniques for the characterization of thin films, nanostructures and nanoparticles will be explained.
