Abstract
The present invention provides a simple, non-destructive and versatile method that enables layer-by-layer (LbL) assembly to be performed on virtually any substrate. A novel catechol-functionalized polymer which adsorbs to virtually all surfaces and can serve as a platform for LbL assembly in a surface-independent fashion is also provided.
Claims (4)
1. A catechol-functionalized polymer comprising the structure:
wherein “x” has a value in the range from 10 to 10,000; and
wherein “y” has a value in the range from 1 to 5,000.
2. The catechol-functionalized polymer of claim 1 wherein “x” is 221 and “y” is 122.
