Getting straight to the point: A peptide–phospholipid-based biomimetic nanocarrier was developed that can transport cargo molecules directly into cytosolic compartments through a non-endocytotic uptake mechanism mediated by scavenger receptor class B type I (SR-BI; see schematic illustration). The fluorescent image shows the cytosolic localization of a dye (red) delivered by the nanocarrier to SR-BI-positive cells (nuclei: blue, membranes: cyan).
