High-Throughput 3D Visualization of Nanoparticles attached to the Surface of Red Blood Cells

Nanoscale, December (2018)
André Dias, Marco Werner, Kevin Ward, Jean-Baptiste Fleury, Vladimir A. Baulin
Blood circulation is the main distribution route for systemic delivery and the possibility to manipulate red blood cells by attaching nanoparticles to their surface provides a great opportunity for cargo delivery into tissues. Nanocarriers attached to red blood cells can be delivered to […]

This study examines the permeability and barrier capacity of a sugar cross-linked resorbable collagen membrane ex vivo and in vivo. In an ex vivo study, injectable platelet-rich fibrin (i-PRF), a peripheral blood-derived human leukocyte-and-platelet-rich plasma was used to analyze membrane permeability. […]

ESR11-F: Delivery of molecular payloads through primary human cell membrane

In-vitro experiments on living cells, toxicology studies
Contact
Andre Dias
Objectives
The goal is to compare and validate the synthetic lipid models to biologically relevant cell types and to investigate how different nano-objects interact with representative lipid single and bilayers compared to human cells with and without therapeutic incorporation.
Tasks and methodology

Cellular uptake of fluorescence-labelled nano-complexes will be checked by […]
