Sub-100 micron multimodal nanoparticles have four main components: 1) a target element (peptides, lipids, antibodies, small molecules, etc.) that can selectively bind to cells, tissues, or organs of the body; 2) a diagnostic agent such as a fluorophore or NMR contrast agent that allows visualization of nanoparticles at the site of delivery and/or a therapeutic or prophylactic agent; 3) an outside 'stealth' layer that allows the particles to evade recognition by immune system components and increase particle circulation half-life; and 4) a biodegradable polymeric material, forming an inner core which can carry therapeutics and release the payloads at a sustained rate after systemic, intraperitoneal, or mucosal administration. These particles possess excellent stability, high loading efficiency, multiple agent encapsulation, targeting and imaging. They are targeted to sites of, or associated with, inflammation caused by a disease, disorder; trauma, chemotherapy or radiation.

Targeted polymeric inflammation-resolving nanoparticles

Provided herein are compositions that contain a nanoparticle containing a plurality of polymers, wherein at least a fraction of the polymers comprise a hydrophobic polymer, a topoisomerase inhibitor, and a Pt-containing chemotherapeutic agent, where the polymers self-assemble in an aqueous liquid to form the nanoparticle, and where the Pt-containing chemotherapeutic agent and the topoisomerase inhibitor are present within the hydrophobic core of the nanoparticle in a ratio of between about 24:1 to about 1:24. Also provided are methods of reducing the proliferation of a cancer cell and methods of treating cancer in a subject that include the use of these compositions. Also provided are methods of making these nanoparticles.

Nanoparticles for targeted delivery of multiple therapeutic agents and methods of use

The present disclosure provides, inter alia, formulation compositions comprising modified nucleic acid molecules which may encode a protein, a protein precursor, or a partially or fully processed form of the protein or a protein precursor. The formulation composition may further include a modified nucleic acid molecule and a delivery agent. The present invention further provides nucleic acids useful for encoding polypeptides capable of modulating a cell's function and/or activity.
