A graphene quantum dots-gadolinium ion chelate (Gd@GQDs) nanomaterial with hydrophilic groups on the surface has a preparation method that includes: preparing graphene oxide by using a Hummers method; subsequently, subjecting the graphene oxide to heating, oxidation, and purification to obtain pure graphene quantum dots; and finally, chelating the graphene quantum dots with Gd.sup.3+ to form stable Gd@GQDs. The Gd@GQDs is easily dispersed in water, phosphate buffered solution (PBS), biological medium and other aqueous system, has good biocompatibility and low cytotoxicity, shows an excellent T.sub.1-weighted contrast performance in a 1.5-Tesla magnetic resonance testing system, and has a relaxation rate r.sub.1 as high as 72 mM.sup.−1s.sup.−1, the value of r.sub.1 being 20 times higher than that of the current commercial T.sub.1-weighted magnetic resonance imaging contrast agent Gd-DTPA.

Described herein are membrane permeabilizing peptides, polynucelotides encoding the peptides, and lipid vesicles comprising the peptides. Furthermore, described herein are methods for using the peptides, polynucleotides, and lipid vesicles for research, diagnosis, disease prevention, and therapeutic treatment.

The disclosure relates to antibodies that bind FcRn and methods of using these antibodies.

Described herein are compositions that may include a triblock self-assembling polypeptide and a molecule attached to the polypeptide. Also described herein are methods of making the compositions and methods of using the compositions.

The present disclosure is directed, in part, to compounds and methods for imaging myocardial perfusion, comprising administering to a patient a contrast agent which comprises a compound that binds MC-1, and an imaging moiety, and scanning the patient using diagnostic imaging.

Acoustically activatable particles having low vaporization energy are disclosed. A particle of material includes a first substance that includes at least one component that has a boiling point below 25° C. at atmospheric pressure. A second substance, different from the first substance, encapsulates the first substance to create the particle. The particle has a core consisting of a liquid and is an activatable phase change agent. The second substance includes a polymeric brush layer to prevent aggregation and coalescence.

A polypeptide conjugate for use in a method for binding and/or internalization of the polypeptide conjugate to a mammalian cell having a transferrin receptor (TFRC) and/or receptor for advanced glycation end products (RAGE). The polypeptide conjugate may be used in a method for targeting of a drug delivery system or diagnostic delivery system.

Provided are compounds and compositions for targeting macrophages and other mannose-binding c-type lectin receptor high expressing cells and methods of treatment and diagnosis using such compounds and compositions.

Provided herein are compositions and methods related to targeted delivery of a therapeutic or diagnostic agent to a subject utilizing an engineered receptor-ligand system, such as an engineered dockerin-cohesin system. As described herein, previously-developed targeted delivery systems for delivering therapeutic and diagnostic agents to a tissue of interest have drawbacks that have not been addressed to date. For example, with respect to the blood-brain barrier (BBB) and the blood-cerebrospinal fluid barrier (BCSFB), both of which hamper delivery of agents to the brain, others have relied on the use of endogenously expressed receptors, like the transferrin receptor, to assist the agent across the barriers.

Pharmaceutical composition comprising antibodies or antigen binding fragments thereof that bind to Globo H, stage-specific embryonic antigen 3 (SSEA-3) and stage-specific embryonic antigen 4 (SSEA-4) are disclosed herein, as well as methods of use thereof. Methods of use include, without limitation, cancer therapies and diagnostics. The antibodies of the disclosure can bind to certain cancer cell surfaces. Exemplary targets of the antibodies disclosed herein can include carcinomas, such as sarcoma, skin cancer, leukemia, lymphoma, brain cancer, glioblastoma, lung cancer, breast cancer, oral cancer, head-and-neck cancer, nasopharyngeal cancer, esophagus cancer, stomach cancer, liver cancer, bile duct cancer, gallbladder cancer, bladder cancer, pancreatic cancer, intestinal cancer, colorectal cancer, kidney cancer, cervix cancer, endometrial cancer, ovarian cancer, testical cancer, buccal cancer, oropharyngeal cancer, laryngeal cancer and prostate cancer.
