Biomimetic monolayer films of monogalactosyldiacylglycerol incorporating plastoquinone
(2015-05-01)
Article
Restricted access - publisher's policyPhotosynthetic organisms use light to convert the inorganic matter in organic one. Photosynthetic process consists on several steps, and one of them involves plastoquinone (PQ) that acts as electron and proton shuttle ... -
Biomimetic monolayer films of monogalactosyldiacylglycerol incorporating ubiquinone
(2012-09-01)
Article
Open AccessUbiquinone and plastoquinone are two of the main electron and proton shuttle molecules in biological systems, and monogalactosyldiacylglycerol (MGDG) is the most abundant lipid in the thylakoid membrane of chloroplasts. ... -
Bottom-up layer-by-layer assembling of antibacterial freestanding nanobiocomposite films
(2018-07-27)
Article
Open AccessIn this study, freestanding nanobiocomposite films were obtained by the sequential deposition of biopolymer-capped silver nanoparticles (AgNPs) and hyaluronic acid (HA). At first, dispersions ofAgNPs decorated with chitosan ... -
