Article
Open AccessIn this work biomimetic monolayers of a MGDG, monogalactosyldiacylglycerol, and DGDG, digalactosyldiacylglycerol mixture (MD), in a ratio close to that of the thylakoid membranes of oxygenic photosynthetic organisms, have ... -
Interactions of cryoprotective agents with phospholipid membranes - A Langmuir monolayer study
(2020-09)
Article
Open AccessThe influence of four common cryoprotectants (dimethyl sulfoxide, glycerol, ethylene glycol and dimethylformamide) on monolayers of four common phospholipids (DPPC, DOPC, POPC and POPE) have been studied using Langmuir ... -
Layer-by-layer bioassembly of cellularized polylactic acid porous 3 membranes for bone tissue engineering
(Springer, 2017-03-22)
Article
Open AccessThe conventional tissue engineering is based on seeding of macroporous scaffold on its surface (“top–down” approach). The main limitation is poor cell viability in the middle of the scaffold due to poor diffusion of oxygen ... -
