Abstract: The present invention is related to the field of intracellular delivery of membrane-impermeable materials. It provides compositions enabling the delivery of such membrane-impermeable materials into cells, applicable for both in vitro, in vivo and ex vivo delivery applications, as well as the use thereof in methods of cytosolic delivery of membrane-impermeable materials. The compositions and methods are particularly useful in biological research, diagnostic methods and the development of cell-based therapies.

Abstract: The present invention in particular relates to the field of micro- and nanoparticles, more in particular to coated nanoparticles. The coatings of the present invention in particular comprise surfactant protein B (SP-B) and one or more lipids. The invention further relates to such coated particles and compositions comprising them for use as a medicament, in particular for use in the treatment of various disorders. Furthermore, the invention provides the use of the compositions of the current invention for delivering one or more agents, such as small interfacing RNA (siRNA) molecules, to the target tissue or cells.

Abstract: The present invention relates to a method and compositions for optimized intracellular delivery of active agents, in particular nucleic acids, using a specific class of adjuvants. The method and compositions of the invention enhance cytosolic release of the agents and can be used for the treatment of various disorders.

Abstract: A method for characterizing extracellular vesicles at an individual level is described. It comprises obtaining a sample comprising extracellular vesicles to be characterized and functionalizing the extracellular vesicles with plasmonic nanoparticles or a plasmonic coating. The method further comprises irradiating the individual extracellular vesicles with a laser beam and detecting a surface enhanced Raman spectroscopy signal from said individual extracellular vesicle.
