Tannic Acid-Mediated Formation of Self-Assembled Nanogel Structures with Pyrene-Modified Chitosan for Enhanced Colloidal Stability and Controlled Solution Viscosity |
| 초록 |
We present the synthesis of pyrene-modified chitosan (Py-CS) nanogels through the hydrophobic interactions and excimer formation of pyrene anchors in aqueous solutions. Tannic acid (TA) was further added to the Py-CS solution as a colloidal stability-enhancing additive by non-covalent secondary interactions such as π-π stacking and hydrogen bonding, which can be observed with fluorescence and FT-IR spectroscopy. Subsequently, solution viscosity of the resulting nanogels was analyzed to evaluate the nanoscale behavior of the modified polysaccharides. |
