Provided are DNA-coated nanoparticles (DNA-NPS), superparamagnetic nanoparticles (DNA-SPNs), and superparamagnetic iron oxide nanopa rticles (DNA-SPIONs) as efficient imaging agents for targeting and imaging atherosclerotic lesions and treating atherosclerotic disease. The DNA-NS, DNA-SPNs, and DNA-SPIONs can enter macrophage cells via the Class A scavenger receptor (SR-A)-mediated pathways and can be used to specifically target atheroscleortic plaques.

The present invention provides a nanoparticle, comprising: a core, wherein the core comprises at least one iron oxide; a shell surrounding the core, wherein the shell comprises at least one polymer; and at least one targeting moiety attached to the shell, wherein the nanoparticle does not comprise boron, for use in methods for detecting and treating cancer in a subject.

Methods and compositions for detecting tau pathology are described. The compositions for detecting tau pathology comprise a targeting ligand that specifically binds to a cell surface marker of tau pathology, wherein the targeting ligand is linked to a liposome that includes an imaging agent. The compositions can be used in a method for imaging tau pathology in a subject that comprises administering to the subject an effective amount of the composition to a subject and imaging at least a portion of the subject to determine if that portion of the subject exhibits tau pathology. The compositions can also be used to detect tau pathology in biological samples obtained from a subject.

Mesoporous silica nanoparticles (MSNs) that may be useful as ultrasound contrast agents for detecting and treating bladder cancer are described herein. The MSNs include a lanthanide, a fluorophore, and an agent detectable by ultrasound.

The present disclosure relates to nanoparticles and the uses thereof in medicine, in particular for the treatment of tumours.

The present disclosure provides a nanocapsule comprising a hydrophilic core; and a hydrophobic shell enclosing the hydrophilic core. The hydrophobic shell contains an outer layer comprising fucoidan, a middle layer comprising carotenoids and metal oxide nanoparticles, and an inner layer comprising fucoidan and contacting the hydrophilic core. The present disclosure also provides use of the nanocapsule as disclosed herein in the manufacture of a medicament for treating and/or diagnosing diseases in a subject in need thereof.

Nanoclusters comprising inorganic nanocrystals and a biodegradable polymer are disclosed. The inorganic nanocrystals have a mean particle size of 1 to 500 nm. The inorganic nanocrystals are contained within a core of the nanoclusters, on the surface of the nanoclusters, contained within a core of the nanoclusters, dispersed throughout the nanoclusters, or a combination thereof. The biodegradable polymer allows the inorganic nanocrystals to be excreted renally over a period of time. The nanoclusters can be used for medical imaging or other biomedical applications.

A method for navigating therapeutic, diagnostic or imaging agents in a vascular network or body cavity is introduced. The method is characterized by high directional gradients and a high magnetic field strength. The latter is used to saturate the magnetization of magnetic therapeutic agents such that when combined with high directional gradients, improved navigation of the magnetic therapeutic agents can be provided at various depths within a patient's body.

Deuterated polymer-biomolecule conjugates and the synthesis and use of deuterated polymer-biomolecule conjugates for detecting the location of specific molecules, e.g., cell surface molecules, in a subject, and for imaging various processes within the body, for detecting the location of molecules associated with disease pathology, and for monitoring disease progression are disclosed.

The present invention relates to a biocompatible nanoparticle and a use thereof and, more specifically, to a biocompatible nanoparticle formed by irradiation an electron beam to an aqueous solution comprising at least one substance selected from the group consisting of a polysaccharide, a derivative thereof and a polyethylene glycol, thereby inducing inter-molecular cross-linking or intra-molecular cross-linking, and to a use of the biocompatible nanoparticle in a drug carrier, a contrast agent, a diagnostic agent or an intestinal adhesion prevention agent or for disease prevention and treatment.
