Our cells don’t live in a vacuum. They are surrounded by a complex, nurturing matrix that is essential for many biological functions, including growth and healing.
In all multicellular organisms, including people, cells make their own extracellular matrix. But in… Read more →
Engineers like to make things that work. And if one wants to make something work using nanoscale components—the size of proteins, antibodies and viruses—mimicking the behavior of cells is a good place to start since cells carry an enormous… Read more →
Previously, chemists have managed to create artificial cell walls and developed synthetic DNA to produce self-replicating, synthetic bacterial cells. Now, for the first time, researchers have used polymers to produce an artificial eukaryotic cell capable of undertaking multiple chemical reactions… Read more →
Researchers at the Univ. of Delaware have developed a “smart” hydrogel that can deliver medicine on demand, in response to mechanical force.
Over the past few decades, smart hydrogels have been created that respond to pH, temperature, DNA, light… Read more →
Artificial bone marrow may be used to reproduce hematopoietic stem cells. A prototype has now been developed by scientists of KIT, the Max Planck Institute for Intelligent Systems, Stuttgart, and Tübingen University. The porous structure possesses essential properties of natural… Read more →
