제목 Synthesis and Characterization of Polymeric Micelles with pH-Sensitive Surface Charge for Enhanced Theranostics
초록 Polymeric micelles as carriers for drugs and imaging agents have been investigated extensively in the past decades. Herein, we designed a nano-sized drug delivery system which has two advantages compared to conventional PEG-based systems. First, the surface of the micelle is neutral at physiological pH and positively charged at tumor pH, that will enhance the uptake of the nanoparticles by cells while reduce the interactions with red blood cell (RBC) during circulation in the blood vessel. Second, compared to PEG, the hydrophilic main chain is biodegradable and the excess hydroxyl group made it possible to be further functionalized by imaging agent and target ligand.
