Dr Cameron Alexander and PhD student George Pasparakis in the University's School of Pharmacy have used polymers — long-chain molecules — to construct capsule-like structures that have properties mimicking the surfaces of a real cell.
In work published as a 'VIP paper' in the journal Angewandte Chemie International Edition, they show how in the laboratory they have been able to encourage the capsules to 'talk' to natural bacteria cells and transfer molecular information.
The breakthrough could have a number of potential medical uses. Among them could be the development of new targeted drug delivery systems, where the capsules would be used to carry drug molecules to attack specific diseased cells in the body, while leaving healthy cells intact, thereby reducing the number of side affects that can be associated with treatments for life-threatening illnesses such as cancer.
The technology could also be used as an anti-microbial agent, allowing doctors to destroy harmful bacteria, without attacking other health-promoting bacteria in the body, which could offer a new weapon in the fight against superbugs.
Dr Cameron Alexander said: “These are very primitive steps in the lab, and still a long way from a true synthetic counterpart to a biological cell, but we have demonstrated that we can transfer certain molecules from inside the synthetic capsule to the bacteria when they are in physical contact, which is an exciting development.
“It's extremely early stages, but it's a move closer to the big experiment when we can one day ask whether a natural cell can think a synthetic cell is one of its own.”

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
