摘要：

Simple immersion of noble metals, oxides, semiconductors, and synthetic polymer substrates in a mussel-mimetic catecholamine polymer solution p(DOMA-AEMA) leads to formation of a thin film on the substrate. The resulting coated substrates can bind DNA without further surface treatment. This approach provides a new entrance to DNA microarray fabrication. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.
