Description
In this study, a novel hydrogel patterning approach using 3D covalent transfer stamping from a fugitive ink is introduced. A model transfer molecule (7-diethylamino-3-(4′maleimidylphenyl)-4-methylcoumarin (CPM)) is absorbed into a 3D fugitive ink stamp made from poly(caprolactone), and then encapsulated in a poly(ethylene glycol) hydrogel. As the CPM diffuses from the fugitive ink to the curing hydrogel it is selectively covalently bound at the boundary of the ink and the hydrogel. Removal of the fugitive ink by solvent exchange leads to a negative copy of interconnected channels patterned with the localized transfer of the molecules at the hydrogel interface. The results suggest that small molecules can be patterned in porous hydrogels in a spatially controllable manner and that the transferred amount can be tuned.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
