“…Pullulan is a flexible water soluble, neutral linear polysaccharide consisting of ␣-1,6 linked maltotriose residues, which is used extensively in the food industry. However, recently pullulan is also being investigated for its biomedical applications in various aspects like targeted drug, gene delivery and diagnostic imaging using quantum dots [3][4][5][6]. Pullulan cannot self-associate in aqueous solutions due to its solubility in water.…”
