Highly branched poly(N-isopropyl acrylamide) functionalized with an inducer molecule suppresses quorum sensing in Chromobacterium violaceum

A new paper showcasing our collaborative work with Dr Shepherd in the University of Sheffield has just been published in ChemComm. This work, writing by Joey Shepherd, Tom Swift, Chien-Yi Chang, James R Boyne, Stephen Rimmer and William Martin showcases how HB-PNIPAM-HL can act as a quorum sensing antagonist and modulate how bacterial organisms communicate with one another.

Ex vivo rabbit and human corneas as models for bacterial and fungal keratitis

Our collaborators in Sheffield have published a paper on using rabbit and human corneas as models for bacterial colonisation. This is very important, relevant work developed on a project in collaboration with the polymer biomaterials group and we will be using in future work. The paper is written by Abigail Pinnock, with Stephen Rimmer, Ian Douglas and Sheila MacNeil as co-authors.

The full paper can be found here.
