A multi-component nanochain for use in diagnostic and therapeutic applications includes at least three nanoparticles linked together to form the nanochain. At least one nanoparticle of the nanochain has an asymmetric surface chemistry defined by asymmetrically disposed first linkers and second linkers. The nanoparticles are linked to form the nanochain by linking first linkers and/or second linkers disposed on separate nanoparticles.

The present invention relates to Adeno-associated virus type 9 methods and materials useful for intrathecal delivery of polynucleotides. Use of the methods and materials is indicated, for example, for treatment of lower motor neuron diseases such as SMA and ALS as well as Pompe disease and lysosomal storage disorders. It is disclosed that administration of a non-ionic, low-osmolar contrast agent, together with a rAA9 vector for the expression of Survival Motor Neuron protein, improves the survival of SMN mutant mice as compared to the administration of the expression vector alone.

Described are amphiphilic polymers that are provided with chelating moieties. The amphiphilic polymers are block copolymers comprising a hydrophilic block and a hydrophobic block, with the chelating moieties linked to the end-group of the hydrophilic block. The disclosed polymers are capable of self-assembly into structures such as micelles and polymersomes. With suitable metals present in the form of coordination complexes with the chelating moieties, the chelating amphiphilic polymers of the invention are suitable for use in various imaging techniques requiring metal labeling, such as MRI (T.sub.1/T.sub.2 weighted contrast agents or CEST contrast agents) SPECT, PET or Spectral CT.

The present invention relates to a CT contrast agent for detecting a thrombus, comprising fibrin-targeted peptide sequence-conjugated glycol chitosan-gold nanoparticles. The CT contrast agent for detecting a thrombus according to an embodiment of the present invention may allow rapid and repeated acquisition of CT image information related to the size and location of a thrombus in cardio-cerebral vascular thrombosis, and also enables the imaging monitoring of cerebral thrombus.

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.
