Fig. 5. Schematic representation of the SNP genotyping method based on a combination of surface ligation chemistry and nanoparticles enhanced SPRi. The two array elements (P and P,) differ only by their last nucleotide at the 3 end. Target DNA (T), ligation probe (L), and Taq DNA ligase are simultaneously introduced. Ligation only occurs with perfect complementary duplexes on the array, leading to extension with the L sequence. The presence of L is detected by gold nanoparticles carrying oligonucleotides (L ) complementary to L. For further details see text. Reprinted from ref. (23) with permission.

Fig. 1 Schematic representation of the manufacture of (super) hydrophobic substrates. Either flat clean silicon samples, coated with a natural oxide film, are considered (left) or samples onto which silica spheres are deposited by means of spin-coating (right). Subsequently, gold nanoparticles are deposited by MPTMS-mediated self-assembly on the silica surface. Finally, PFOTS is adsorbed onto the exposed silica areas to provide sufficient stability, while DDT is deposited onto the gold surface to lower its surface energy...
