Absolutely thrilled this is out🥳Our review explores why antibiotics often fail even when bacteria is susceptible in the lab. From phenotypic resilience and biofilm formation to host microenvironment, we dive into many factors behind these discrepancies

Another paper from @microberamon.bsky.social's PhD 🦠 Two structural variants of an AMP-inspired antimicrobial polymer have different effects on P. aeruginosa. One kills with a bang, the other with a whimper pubs.acs.org/doi/10.1021/... #MicroSky @sebperrier.bsky.social @alexiahapeshi.bsky.social

A cartoon showing a Gram-negative bacterium exposed to two variants of a polymer. A triblock structure causes formation of multiple small pores in the outer membrane. A diblock structure causes large pores in both outer and inner membranes, and cell lysis.

🧼 a-D50 acts in a surfactant-like way, stripping lipids
🕳️ a-T100-1 forms pores in the membrane
Same chemistry, different architecture → different mechanisms.

🎉 Super happy to finally share our new paper in ACS Biomacromolecules!
We used AFM & neutron reflectometry to study how two SNAPs (synthetic nanoengineered antimicrobial polymers) disrupt P. aeruginosa membranes.

Absolutely thrilled to present our latest review, where we discuss how host microenvironment and bacterial subversion strategies can undermine traditional antimicrobial sensitivity testing, and whether better models may one day get us "beyond the MIC" #IDSKy
