ABSTRACT:
Provided are methods of detecting a nucleic acid using nanoparticles having oligonucleotides attached on the surface. The methods comprise contacting the nucleic acid with one or more types of particles having oligonucleotides attached on the surface. The oligonucleotides attached to nanoparticles have sequences complementary to at least a portion of the sequence of the nucleic acid. A detectable change (preferably a color change) is brought about as a result of the hybridization of the oligonucleotides on the nanoparticles to the nucleic acid. Also provided are compns. and kits comprising nanoparticles made of gold and oligonucleotides labeled with fluorescent mols. The invention further provides nanomaterials and nanostructures comprising nanoparticles and methods of nanofabrication utilizing the nanoparticles. A method of sepg. a selected nucleic acid from other nucleic acids is also described.
