제목 One-Pot Encapsulation of Nile Red via Protein-Polymer Conjugation
초록 Polymeric micelles have emerged as a novel promising colloidal carrier for the targeting of poorly water soluble drugs and nanoparticles. Herein we describe a one pot method for encapsulation of Nile Red into micellar aggregates using nickel complexed (nitrilotriacetic acid)-end-functionalized polystyrene (Ni-NTA-PS) and histidine-tagged green fluorescent protein (His-tagged GFP) in water/DMF (DMF 4 vol %). When Ni-NTA-PS and Nile Red dissolved in DMF was added slowly into PBS buffer containing His-tagged GFP, GFP coated micellar aggregates were formed and Nile Reds were encapsulated inside the micellar aggregates at once. The formation of micellar aggregate was confirmed by transmission electron microscopy (TEM) measurement and dynamic light scattering (DLS) study. Encapsulation of Nile Red was confirmed by photoluminescence (PL) spectroscopy and fluorescent microscopy.
