Silica nanocarriers hybridized with superparamagnetic iron oxide nanoparticles (SPIONs) and curcumin through equilibrium or enforced adsorption technique. Methods for dual delivery of SPIONs and curcumin to a target for diagnosis or therapy, for example, for SPION-based magnetic resonance imaging or for targeted delivery of curcumin to a cell or tissue. The technique can be extend to co-precipitation of mixed metal oxide involving Ni, Mn, Co and Cu oxide. The calcination temperature can be varied from 500-900 C. The nanocombination is functionalized with chitosan, polyacrylic acid, PLGA or another agent to increase its biocompatibility in vivo.

Disclosed are compositions comprising polymeric nanoparticles and methods of using the same. The polymeric nanopartides can be conjugated with a targeting ligand that is a substrate for a solid tumor-specific cell protein. The polymeric nanoparticles can also comprises an imaging compound and/or a therapeutic agent encapsulated in the hydrophobic interior of the nanoparticle. A cancer therapeutic composition comprising the nanoparticle is also disclosed. The disclosed nanoparticles can be used to target and deliver imaging and/or therapueitc compounds to cancer cells, thereby identifying and/or treating a solid tumor cell target. Methods for treating cancer, such as lung cancer, using the polymeric nanoparticles are also disclosed.

The present invention provides hydrophilic bilirubin derivative particles containing a metal, a use thereof, and a preparation method therefor. The bilirubin derivative particles of the present invention form coordinate bonds with various metals, and thus can be used in MR diagnosis, CT diagnosis, photo-acoustic diagnosis, PET diagnosis, or optical diagnosis. The bilirubin derivative particles of the present invention can release an anticancer drug encapsulated therein to the outside by the combination with a platinum-based anticancer drug and the degradation by a stimulation of light/reactive oxygen species, and exhibit anti-inflammatory and anticancer activities, and thus the bilirubin derivative particles of the present invention have a concept of theranostics in which the bilirubin derivative particles can be for therapeutic uses as well as diagnostic uses.

The present invention relates to a recombinant self-assembled protein comprising a target-oriented peptide and a use thereof The recombinant self-assembled protein according to the present invention, comprising a target-oriented peptide, does not require an additional process for providing target-orientedness, and is thus capable of delivering a desired drug to a target tissue or target cell without using additives, such as chemical binders or stabilizers; therefore, the protein can be used for photothermal therapy, drug delivery, imaging, or the like. In particular, according to the present invention, it is possible to prepare gold-protein nanoparticle fusions in which uniform high-density gold nanoparticles having target-orientedness are bound to protein surfaces, without an additional process of surface stabilization or process for providing target-orientedness. Compared with conventional gold nanoparticles, the gold-protein nanoparticle fusions according to the present invention show structural stability against pH variation and concentration variation, and also have excellent target-orientedness; therefore, the fusions can bring a dramatic enhancement to the utilization of gold nanoparticles in photothermal therapy.
