Abstract: The present invention generally relates to a method of using NMR relaxation rates (R2) of water molecules as an indicator of the extent of aggregation of biopharmaceutical formulations. The biopharmaceutical can be evaluated nondestructively without the vial or container being opened or protective seal compromised (i.e., broken). The method is applicable to all biopharmaceuticals and the water signal obtained by magnetic resonance relaxometry is very strong and sensitive because water is used as the solvent and is present in high (>90%) concentrations in every biopharmaceutical formulation.

Abstract: The compositions and methods disclosed herein pertain to the manufacture and use of hydrogels. The disclosed compositions and methods pertain to hydrogels capable of induction by a variety of methodologies, such as by pH, salt and/or mixing. Such hydrogels are capable of self- or co-assembly and while doing so, may entrap a variety of bioactive agents in their native form, such as proteins, DNA, RNA and the like. The hydrogels of the present invention also demonstrate rapid sheer-responsiveness. The hydrogels of the present invention are biodegradable, biocompatible and useful as a biomaterial or drug-delivery device.

Abstract: Techniques include determining, non-invasively and without applying deformational stress, a nuclear magnetic resonance relaxation rate at a volume inside a subject. The method also includes determining a mechanical property of material at the volume inside the subject based on the nuclear magnetic resonance relaxation rate.

Abstract: The present invention provides for monodispersed dendrimers having a core, branches and periphery ends, wherein the number of branches increases exponentially from the core to the periphery end and the length of the branches increases exponentially from the periphery end to the core, thereby providing for attachment of chemical species at the periphery ends without exhibiting steric hindrance.

Abstract: Compositions for producing multi-chromic (“color”) magnetic resonance images (MRI). The compositions for use as MRI imaging agents include a magnetic resonance imaging tracer having a signal emitter, such as a 19F imaging tracer (19FIT), conjugated with a magnetic signal modulator, such as a paramagnetic functional group or a paramagnetic ion. The 19FIT and the signal modulator (M) are joined covalently by a chelator such as DOTA, forming a nanometer-sized fluorinated paramagnetic complex 19FIT-DOTA-M. Other signal emitters, such as 31P imaging tracer (31PIT), can also be modulated using this strategy (i.e., 31PIT-DOTA-M) to generate multi-chromic 31P MRI or MRS.
