    摘要: A nanostructure comprises a MOX NP and a bidentate ligand on a surface of the MOX NP. A cancer recognition molecule is covalent coupled to the surface of the MOX NP via the bidentate ligand. A biocatalyst is also coupled to the surface of the MOX nanoparticle via the bidentate ligand. The cancer recognition molecule includes a structure configured to selectively recognize a corresponding antigen on a surface of a cancer cell and bind to the antigen. The biocatalyst is structured to selectively catalyze the oxidation of a light emitting compound to produce photons. The photons transform the MOX NPs into an excited state such that the MOX NPs generate reactive oxygen species (ROS) in the vicinity of the cancer cells in the excited state. The reactive oxygen species lyse or cause apoptosis in the cancer cells in situ. The biocatalyst includes luciferase and the light emitting compound includes luciferin.

    摘要: Compositions and methods for assessing inflammation in a subject. The preset disclosure provides compositions for labeling leukocytes with a 19F-containing perfluoropolyether molecule ex vivo. In some examples, the leukocytes are obtained from the patient, enriched in a whole blood fraction, and then labeled. The labeled cells may be re-introduced into the patient. The leukocytes may accumulate at a site of inflammation, thus permitting non-invasive evaluation of inflammation in patients. The present methods provide a tool for assessing inflammation in a wide variety of autoimmune diseases and may have particular utility in intestinal diseases such as Crohn's disease, ulcerative colitis, inflammatory bowel disease, and cardio myositis.

    摘要: Disclosed are novel, targeting, paramagnetic nanoparticles as contrast agent for magnetic resonance imaging. The compositions of the nanoparticles are composed of self-assembled polyelectrolyte biopolymers having targeting moieties, which can suitable for targeted delivery of paramagnetic ions complexed to the nanoparticles. The nanoparticulate contrast agent can internalize into the targeted tumor cells to realize the receptor mediated uptake, and therefore afford enhanced relaxivity and improved signal-to-noise effect on the examined tissue areas. Methods for making these targeting MRI contrast agents are also provided.

    摘要: A marker delivery device includes an elongated delivery cannula which has a distal end section, an inner lumen and a discharge opening in the distal end section in communication with the inner lumen. At least one elongated fibrous marker body is slidably disposed within the inner lumen of the elongated delivery cannula. The at least one elongated fibrous marker body includes a plurality of bioabsorbable polymeric strands. The strands are compressed to a compressed configuration and bound together in the compressed configuration with a polymer binding agent prior to insertion into the elongated delivery cannula. A releasable plug is disposed within a distal portion of the inner lumen and distal to the at least one elongated fibrous marker body so as to at least partially occlude the discharge opening in the distal end section.
