| 5 | In vivo polydopamine coating of Rhodobacter sphaeroides for enhanced electron transfer显示文摘Recent advances in coupling light-harvesting microorganisms with electronic components have led to a new generation of biohybrid devices based on microbial photocatalysts.These devices are limited by the poorly conductive interface between phototrophs and synthetic materials that inhibit charge transfer.This study focuses on overcoming this bottleneck through the metabolically-driven encapsulation of photosynthetic cells with a bio-inspired conductive polymer.Cells of the purple non sulfur bacterium Rhodobacter sphaeroides were coated with a polydopamine(PDA)nanoparticle layer via the self-polymerization of dopamine under anaerobic conditions.The treated cells show preserved light absorption of the photosynthetic pigments in the presence of dopamine concentrations ranging between 0.05–3.5 mM.The thickness and nanoparticle formation of the membrane-associated PDA matrix were further shown to vary with the dopamine concentrations in this range.Compared to uncoated cells,the encapsulated cells show up to a 20-fold enhancement in transient photocurrent measurements under mediatorless conditions.The biologically synthesized PDA can thus act as a matrix for electronically coupling the light-harvesting metabolisms of cells with conductive surfaces. | Rossella Labarile Danilo Vona Maria Varsalona Matteo Grattieri Melania Reggente Roberto Comparelli Gianluca M.Farinola Fabian Fischer Ardemis A.Boghossian Massimo Trotta | 2024 | Nano Research2024，17，2： | 0 |
| 6 | Coupling effects in QD dimers at sub-nanometer interparticle distance显示文摘Currently,intensive research efforts focus on the fabrication of meso-structures of assembled colloidal quantum dots(QDs)with original optical and electronic properties.Such collective features originate from the QDs coupling,depending on the number of connected units and their distance.However,the development of general methodologies to assemble colloidal QD with precise stoichiometry and particle-particle spacing remains a key challenge.Here,we demonstrate that dimers of CdSe QDs,stable in solution,can be obtained by engineering QD surface chemistry,reducing the surface steric hindrance and favoring the link between two QDs.The connection is made by using alkyl dithiols as bifunctional linkers and different chain lengths are used to tune the interparticle distance from few nm down to 0.5 nm.The spectroscopic investigation highlights that coupling phenomena between the QDs in dimers are strongly dependent on the interparticle distance and QD size,ultimately affecting the exciton dissociation efficiency. | Carlo Nazareno Dibenedetto Elisabetta Fanizza Rosaria Brescia Yuval Kolodny Sergei Remennik Annamaria Panniello Nicoletta Depalo Shira Yochelis Roberto Comparelli Angela Agostiano Maria Lucia Curri Yossi Paltiel Marinella Striccoli | 2020 | Nano Research2020，13，4： | 0 |
