Liposomal coating of near infrared resonant magnetic-plasmonic nanostars for blood-brain barrier-like passage, selective targeting, and bioorthogonal surface-enhanced Raman scattering imaging.
HYPOTHESIS A flexible phospholipid bilayer can conformally coat highly anisotropic iron oxide@gold nanostars (M@NSts), maintain colloidal stability over 7 days, and preserve magnetic manipulability and near-infrared (NIR) plasmonic properties. Embedding a hydrophobic bioorthogonal Raman reporter within the membrane sho...
