| 제목 | Tannin/Biopolymer Complex as a Potential Antimicrobial Glue |
| 초록 | Plant-derived tannin derivatives show molecular affinity to biopolymers, resulting supramolecular assembly. Astringent taste of tannin-containing food arises from the attachment of tannins to the proteins on tongue, indicating strong interaction even in the presence of saliva. Recent studies have suggested that these tannin/biopolymer complexes can be used as water-resistant bioadhesives. Herein, we report an antimicrobial coating based on tannin/biopolymer complexes as surface-attached reservoir for tannins that possesses intrinsic antimicrobial activity. We compared supramolecular assembly of various tannins with poly(ethylene glycol) (PEG), and evaluated stability. The complexes were pasted on a variety of surface as a reservoir releasing tannins for antimicrobial activity. **This work was carried out with the support of "Cooperative Research Program for Agriculture Science and Technology Development (Project No. PJ01323201)" Rural Development Administration, Republic of Korea. |
