Abstract
The hybridisation of thiol-modified single-stranded DNA (SH-ssDNA) embedded in lipoate or hydrophilic polymer monolayers on gold have been studied through the technique of surface plasmon resonance (SPR). SH-ssDNA and the blocking agents
were co-adsorbed on gold from the same solution or the surface was
post-treated with the blocking agents. The assembling process is allowed
to take place for only 10 min. Binding of
non-complementary and complementary DNA is dependent both on the
blocking agent and on the assembling method used. The lowest
non-complementary binding and the highest complementary binding of DNA
was obtained with a layer assembled from a binary solution of SH-ssDNA
and the lipoate blocking agent.
