Patent number: 7208587Abstract: The invention provides methods of detecting a nucleic acid. The methods comprise contacting the nucleic acid with one or more types of particles having oligonucleotides attached thereto. In one embodiment of the method, the oligonucleotides are attached to nanoparticles and have sequences complementary to portions 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. The invention also provides compositions and kits comprising particles. The invention further provides methods of synthesizing unique nanoparticle-oligonucleotide conjugates, the conjugates produced by the methods, and methods of using the conjugates. In addition, the invention provides nanomaterials and nanostructures comprising nanoparticles and methods of nanofabrication utilizing nanoparticles. Finally, the invention provides a method of separating a selected nucleic acid from other nucleic acids.Type: GrantFiled: August 13, 2003Date of Patent: April 24, 2007Assignee: Nanosphere, Inc.Inventors: Chad A.

Publication number: 20040131843Abstract: The invention provides methods of nanolithography and products therefor and produced thereby. In particular, the invention provides a nanolithographic method referred to as high force nanografting (HFN). HFN utilizes a tip (e.g., a scanning probe microscope (SPM) tip such as an atomic force microscope (AFM) tip) to pattern a substrate passivated with a resist, In the presence of a patterning compound, the tip is used to apply a high force to the substrate to remove molecules of the resist from the substrate, whereupon molecules of the patterning compound are able to attach to the substrate the form the desired pattern.Type: ApplicationFiled: February 2, 2004Publication date: July 8, 2004Inventors: Chad A Mirkin, Peter V Schwartz, James J Storhoff, So-Jung Park

Publication number: 20030068446Abstract: Ultrahigh resolution patterning, preferably carried out by dip-pen nanolithographic printing, can be used to construct peptide and protein nanoarrays with nanometer-level dimensions. The peptide and protein nanoarrays, for example, exhibit almost no detectable nonspecific binding of proteins to their passivated portions. This work demonstrates how dip pen nanolithographic printing can be used in a method to generate high density protein and peptide patterns, which exhibit bioactivity and virtually no non-specific adsorption. It also shows that one can use AFM-based screening procedures to study the reactivity of the features that comprise such nanoarrays. The method encompasses a wide range of protein and peptide structures including, for example, enzymes and antibodies. Features at or below 300 nm can be achieved.Type: ApplicationFiled: October 2, 2002Publication date: April 10, 2003Applicant: Northwestern UniversityInventors: Chad A.
