Abstract:
PROBLEM TO BE SOLVED: To provide nanoparticles and pharmaceutical compositions comprising the nanoparticles to be used, inter alia, for detection and treatment of tumors and inflammations.SOLUTION: The invention provides nanoparticles consisting of a polymer which is a metal chelating agent coated with a magnetic metal oxide, wherein at least one active agent is covalently bound to the polymer. The nanoparticles may optionally further comprise at least one active agent physically or covalently bound to the outer surface of the magnetic metal oxide.
Abstract:
Disclosed is a water-soluble near infrared fluorescent material that emits a near infrared light, can be used in an in vivo imaging method and has a high quantum yield. Also disclosed is a multimodal water-soluble near infrared fluorescent material having a high quantum yield that can be used in a multimodal in vivo imaging method using light (fluorescent) imaging, MRI, SPECT and the like. The water-soluble near infrared fluorescent material comprises a semiconductor quantum dot having an emission band in a near infrared region and a covering layer covering the surface of the semiconductor quantum dot. The covering layer is a layer comprising covered peptides selected from the group consisting of cysteines, and peptides that comprise 2 to 8 amino acid residues and contain one or more cysteine residues in the amino acid residue.
Abstract:
Capsules and particles with at least one encapsulated and/or entrapped agent, such as therapeutic agent, imaging agents, and other constituents may be produced by electrohydrodynamic processes. More particularly, the agent encapsulated in a vehicle, capsule, particle, vector, or carrier may maximize treatment and/or imaging of malignant cancers while minimizing the adverse effects of treatment and/or imaging.
