Biomimetic detection of aminoglycosidic antibiotics using polydiacetylene-phospholipids supramolecules

We rationally designed highly sensitive and selective polydiacetylene (PDA)-phospholipids liposomes for the facile detection of aminoglycosidic antibiotics. The detecting mechanism mimics the cellular membrane interactions between neomycin and phosphatidylinositol-4,5-bisphosphate (PIP2) phospholipids. The developed PDA-PIP2 sensory system showed a detection limit of 61 ppb for neomycin and was very specific to aminoglycosidic antibodies only.
