Abstract: Disclosed are biomimetic proteolipid nanovesicles that possess remarkable properties for targeting compounds of interest to particular mammalian cell and tissue types. In particular embodiments, drug delivery vehicles are provided composed of synthetic phospholipids and cholesterol, enriched of leukocyte membranes, and surrounding an aqueous core. These nanovesicles are able to both avoid the immune system, thanks to the presence on their surface of self-tolerance proteins, as CD-45, CD-47, and MHC-1, and target inflamed endothelium, thereby diffusing in the tumor microenvironment. These properties make the composition highly suited for targeted drug delivery to mammalian tumor cells in vitro and in situ.

Abstract: A new fractionation device shows desirable features for exploratory screening and biomarker discovery. The constituent MSCs may be tailored for desired pore sizes and surface properties and for the sequestration and enrichment of extremely low abundant protein and peptides in desired ranges of the mass/charge spectrum. The MSCs are effective in yielding reproducible extracts from complex biological samples as small as 10 ?l in a time as short as 30 minutes. They are inexpensive to manufacture, and allow for scaled up production to attain the simultaneous processing of a large number of samples. The MSCs are multiplexed, label-free diagnostic tools with the potential of biological recognition moiety modification for enhanced specificity. The MSCs may store, protect and stabilize biological fluids, enabling the simplified and cost-effective collection and transportation of clinical samples.
