Bioengineered Bacterial Vesicles and Biomimetic Hybrids Eliminate Biofilms and Balance the Gut Microbiome Biomimetic nanocarriers based on liposomes and Myxobacteria outer-membrane vesicles (OMVs) are effective antibiotic delivery systems. Hybrids have a higher drug loading and can target intracellular p...

We published a new manuscript in Small, which evaluates different methods of #extracellularvesicle hybridisation and their impact on (pathogenic) bacteria 👇.
Congrats to our PhD student Leila for this wonderful work! 👩‍🔬🎉🧫

A man and a woman having a race. The man has a relatively clear path with two hurdles and the woman’s path is filled with obstacles and dangers and she is wearing a ball chained to her ankle.

Our very first imaging of EVs by super resolution microscopy with the ONI Nanoimager was quite the experience. Thank you Peter and Siobhan for the excellent introduction and training!

How can medicines be directed to the precise location within the body where they need to act? Research lead by ETH Zurich have now unveiled a special class of effective particles. They appear visually striking under a microscope too, resembling tiny paper flowers or desert roses.

The science behind winning a Nobel Prize? Being a man from a wealthy family | Torsten Bell A lot of talent is wasted in a world where more than half of laureates come from households in the richest 5%

"If talent and opportunity were equally distributed, the average winner would come from a middle income background.

The reality?

The average laureate grew up in a household just below the top 10%. More than 50% come from the top 5%"

Like me, you might be frustrated at the amount of overlapping and photoshopped images in science papers that we sleuths are finding.
But what is even more frustrating is the lack of response and action from journals.
Here is a thread with some outrageous examples.
