Abstract: Biosensors and methods for localized surface plasmon resonance biosensing are disclosed. The biosensor can include a substrate having a substrate surface to which a plurality of localized surface plasmon resonance (LSPR) antennae are affixed. The LSPR antennae can be affixed via an affixation surface of the LSPR antenna. The LSPR antennae can have a functional surface opposite the affixation surface. Each functional surface can be functionalized by a plurality of single-stranded DNA.

Abstract: Disclosed herein is a plasmonic molecular device consisting photoisomerizable molecular switch-tethered gold triangular nanoprisms and methods for using such device for the detection of biomarkers. The molecular device exhibits unprecedentedly large localized surface plasmon resonance shifts during the photoisomerization of molecular switches. The fabricated molecular device with zwitterionic structure has been utilized to develop adaptable nanoplasmonic biosensor for ultrasensitive. highly specific and programmable detection of microRNAs and proteins from patient biofluids.

Abstract: Provided is planar electro-magnetic device with both inductive and capacitive characteristics comprising a calcium copper titanate CCTO nanoparticle film.

Abstract: The invention provides methods and compositions having at least one asymmetrically functionalized nanoparticle. An asymmetrically functionalized nanoparticle can comprise a nanoparticle core having an outer surface, a primary group of first ligands attached to a substantially continuous primary region of the outer surface, and a secondary group of second ligands attached to a substantially continuous secondary region of the outer surface, such that the primary group of first ligands and the secondary group of second ligands comprise a different ligand population.

Abstract: The invention provides methods and compositions having one-dimensional nanoparticle chains. A one-dimensional nanoparticle chain can comprise a linear substantially non-crosslinked polymer having pendant groups and asymmetrically functionalized nanoparticles attached to the polymer through the pendant groups. Additionally, an asymmetrically functionalized nanoparticle can comprise a nanoparticle core having an outer surface, a primary group of first ligands attached to a substantially continuous primary region of the outer surface, and a secondary group of second ligands attached to a substantially continuous secondary region of the outer surface, such that the primary group of first ligands and the secondary group of second ligands comprise a different ligand population.

Abstract: A method of synthesizing ligand-capped metal nanoparticles is disclosed and described. A method of synthesizing ligand-capped metal nanoparticles can comprise reacting a metal salt with 9-borabicyclo [3.3.1] nonane as a reducing agent in the presence of a capping ligand to form the ligand-capped metal nanoparticles. The method can be a single step approach which also significantly broadens choices for capping agents which can be readily incorporated during formation of the metal nanoparticles.
