    "abstract": "DNA melting and hybridization is a fundamental biological process as well as\na crucial step in many modern biotechnology applications. DNA confined on\nsurfaces exhibits different behavior from that in free solutions. The system of\nDNA-capped gold nanoparticles exhibits unique phase transitions and represents\na new class of complex fluids. Depending on the sequence of the DNA, particles\ncan be linked to each other through direct complementary DNA sequences or via a\n``linker\u0027\u0027 DNA whose sequence is complementary to the sequence attached to the\ngold nanoparticles. We observed different melting transitions for these two\ndistinct systems.",
