An article from the Zelikin lab just published in Bioconjugate Chemistry has been selected as the American Chemical Society Editor´s Choice (the one article chosen each day from the entire ACS portfolio to be highlighted for quality and/or broad interest).
Creating artificial cells with a dynamic cytoskeleton, akin to those in living cells, is a major goal in bottom-up synthetic biology. In this study, we demonstrate the in situ polymerization of microtubules encapsulated in giant polymer-lipid hybrid vesicles (GHVs) composed of 1,2-dioleoyl-sn-glycero-3-phosphocholine and an amphiphilic block copolymer. The block copolymer is comprised of poly(cholesteryl methacrylate-co-butyl methacrylate) as the hydrophobic block and either…
The integration of artificial and mammalian cells into semi-synthetic aggregates remains a challenge in bottom-up synthetic biology. Here, the fabrication of cell membrane vesicles (CMV) from HepG2 cells and their use as a coating for alginate microgels to produce camouflaged artificial cells (ACs) is demonstrated. These ACs are used for the assembly of either synthetic aggregates or semi-synthetic aggregates. In the first case, a predator-defendant and a liver-like synthetic aggregates are…
A new perspective article by 57 international researchers, including Associate Professor Ebbe Sloth Andersen, outlines a roadmap for the synthesis of life. The paper explores key traits like resilience, sustainability, and evolution, and how synthetic life could revolutionize biotechnology, medicine, and materials science.
Multivalency as an interaction principle is widely utilized in nature. It enables specific and strong binding by multiple weak interactions through enhanced avidity and is a core process in immune recognition and cellular signaling, which is also a current concept in drug design. Here, we use the high signals from plasmon-enhanced fluorescence of nanoparticles to extract binding kinetics and dynamics of multivalent interactions on the single-molecule level and in real time. We study mono-, bi-,…
