Orthogonal assembly of nanoparticle building blocks on dip-pen nanolithographically generated templates of DNA.
Nanoscale construction work with DNA: Dip-pen nanolithography (DPN) is used to generate nanostructures which can be subsequently functionalized with oligonucleotides a' and b' and used to assemble, in an orthogonal manner, gold nanoparticles (a, b in scheme) functionalized with sequences complementary to the DPN-generated structures.
