Regenerative Core-Shell Nanoparticles for Simultaneous Removal and Detection of Endotoxins.

Detection and removal of lipopolysaccharides (LPS) from food and pharmaceutical preparations is important for their safe intake and administration to avoid septic shock. We have developed an abiotic system for reversible capture, removal, and detection of LPS in aqueous solutions. Our system comprises long C18 acyl chains tethered to FeO/Au/FeO nanoflowers (NFs) that act as solid supports during the separation process.
