20110137079 | METAL OXIDE-CHELATING LIGANDS - A compound having the formula below. The values n and m are independently selected positive integers. | 06-09-2011 |
20120248409 | Simultaneous Modulation of Quantum Dot Photoluminescence using Orthogonal Fluorescence Resonance Energy Transfer (FRET) and Charge Transfer Quenching (CTQ) - Quantum dots are modified with varying amounts of (a) a redox-active moiety effective to perform charge transfer quenching, and (b) a fluorescent dye effective to perform fluorescence resonance energy transfer (FRET), so that the modified quantum dots have a plurality of photophysical properties. The FRET and charge transfer pathways operate independently, providing for two channels of control for varying luminescence of quantum dots having the same innate properties. | 10-04-2012 |
20130045499 | Compact Multifunctional Ligand to Enhance Colloidal Stability of Nanoparticles - A ligand design allows compact nanoparticle materials, such as quantum dots (QDs), with excellent colloidal stability over a wide range of pH and under high salt concentrations. Self-assembled biomolecular conjugates with QDs can be obtained which are stable in biological environments. Energy transfer with these ligands is maximized by minimizing distances between QDs/nanoparticles and donors/acceptors directly attached to the ligands or assembled on their surfaces. | 02-21-2013 |
20130129627 | Delivery of Nanoparticles to Neurons - A peptide attached to a nanoparticles (such as quantum dots) selectively directs the nanoparticles to neurons in a tissue or organism. | 05-23-2013 |
20130323777 | Compact Multifunctional Ligand to Enhance Colloidal Stability of Nanoparticles - A ligand design allows compact nanoparticle materials, such as quantum dots (QDs), with excellent colloidal stability over a wide range of pH and under high salt concentrations. Self-assembled biomolecular conjugates with QDs can be obtained which are stable in biological environments.

20150147803 | Coatings of Semiconductor Quantum Dots for Improved Visibility of Electrodes and Pipettes - A glass pipette such as an electrode for electrophysiological recording is coated with quantum dots. This greatly aids the ability to observe the glass pipette, particular in tissue as the quantum dots provide an excellent performance under two-photon illumination used to visualize objects at depths of hundreds of microns. | 05-28-2015 |
