| Research Abstract |
Tailor-made functional nanogels and hydrogels were could created by self-assembly of functional associating polysaccharides. In particular, hydrophobized polysaccharides such as cholesterol-bearing pullulans formed physically cross-linked nanogels by their self-assembly in water. The nanogels can form complexes with proteins and nucleic acids. Macrogels with well-defined nanostructures can be obtained by self-assembly using these nanogels as building blocks. The self-assembling method using associating polymers is an efficient and versatile technique for preparing functional nanogels and hydrogels for application to bionanotechnology such as drug delivery system and artificial molecular chaperone. Nanogel-inorganic hybrid nanomaterials about nanogel-calcium phosphate and nanogel-Quantum dots were also described.
