The cell wall and cytoplasmic MreB polymers are important for bacterial cell shape. However, Spiroplasma cells lack a cell wall and still display a helical shape and kink-based motility, which is thought to rely on five MreB isoforms and a fibril pro

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-12 (2018)

Multi-compartmentalised soft micro-systems are used as models of synthetic protocells. Here, the authors developed nested host–guest protocell constructs capable of self-reconfiguration in response to changes in pH generated by antagonistic modes o

Bulk, one step generation of single-core double emulsions from polymer-osmose-induced aqueous phase separation in polar oil droplets

Autor: Jean-Paul Douliez, Arnaud Saint Jalmes

International audience; Double water-in-oil-in-water (W/O/W) emulsions are aqueous droplet(s) embedded within oil droplets dispersed in a continuous water phase. They are exploited for many applications from cosmetic to food science since both hydros
