Resistance of Oil‐Infused PDMS with Different Macroporosities Against Bacterial Attachment

Advanced Materials Interfaces, EarlyView.
In this study, a series of environmentally benign, nonfluorinated liquid paraffin‐infused porous PDMS networks with varying porosities is created. By introducing different homogenous and heterogenous bulk structures and varying interfacial roughness by sugar and salt templating, the role of porosity and oil availability on the resistance against ...

Validation of the 3-under-2 principle of cell wall growth in Gram-positive bacteria by simulation of a simple coarse-grained model

, 2017
The aim of this work is to propose a first coarse-grained model of Bacillus subtilis cell wall, handling explicitly the existence of multiple layers of peptidoglycans. In this first work, we aim at the validation of the recently proposed "three under two"
