271 results about "Binding energy" patented technology

In physics, binding energy (also called separation energy) is the minimum energy required to disassemble a system of particles into separate parts. This energy is equal to the mass defect minus the amount of energy, or mass, that is released when a bound system (which typically has a lower potential energy than the sum of its constituent parts) is created, and is what keeps the system together.

System and method for use of nanoparticles in imaging and temperature measurement

This invention provides a system and method that improves the sensitivity and localization capabilities of Magnetic Particle Imaging (MPI) by using combinations of time-varying and static magnetic fields. Combinations of magnetic fields can be used to distribute the signals coming from the magnetic particles among the harmonics and other frequencies in specific ways to improve sensitivity and to provide localization information to speed up or improve the signal-to-noise ratio (SNR) of imaging and / or eliminate the need for saturation fields currently used in MPI. In various embodiments, coils can be provided to extend the sub-saturation region in which nanoparticles reside; to provide a static field offset to bring nanoparticles nearer to saturation; to introduce even and odd harmonics that can be observed; and / or to introduce combinations of frequencies for more-defined observation of signals from nanoparticles. Further embodiments provide for reading of the signal produced by cyclically saturated magnetic nanoparticles in a sample so as to provide a measurement of the temperature of those nanoparticles. The spectral distribution of the signal generated provides estimates of the temperature of the nanoparticles. Related factors may also be estimated—binding energies of the nanoparticles, phase changes, bound fraction of the particles or stiffness of the materials in which the nanoparticles are imbedded.

Protein-protein interactions and methods for identifying interacting proteins and the amino acid sequence at the site of interaction

The invention relates to protein-protein interactions and methods for identifying interacting proteins and the amino acid sequence at the site of interaction. Using overlapping hexapeptides that encode for the entire amino acid sequences of the linker domains of human P-glycoprotein gene 1 and 3 (HP-gp1 and HP-gp3), a direct and specific binding between HP-gp1 and 3 linker domains and intracellular proteins was demonstrated. Three different stretches (617EKGIYFKLVTM627, (SEQ ID NO: 1) 658SRSSLIRKRSTRRSVRGSQA677 (SEQ ID NO: 2) and 694PVSFWRIMKLNLT706 (SEQ ID NO: 3) for HP-gp1 and 618LMKKEGVYFKLVNM631 (SEQ ID NO: 4), 648KAATRMAPNGWKSRLFRHSTQKNLKNS674 (SEQ ID NO: 5), and 695PVSFLKVLKLNKT707 (SEQ ID NO: 6) for HP-gp3) in linker domains bound to proteins with apparent molecular masses of ˜80 kDa, 57 kDa and 30 kDa. The binding of the 57 kDa protein was further characterized. Purification and partial N-terminal amino acid sequencing of the 57 kDa protein showed that it encodes the N-terminal amino acids of alpha and beta-tubulins. The method of the present invention was further validated with Annexin. The present invention thus demonstrates a novel concept whereby the interactions between two proteins are mediated by strings of few amino acids with high and repulsive binding energies, enabling the identification of high affinity binding sites between any interacting proteins.
