Abstract: The present disclosure provides compositions and methods for efficient and effective protein delivery in vitro and in vivo. In some aspects, proteins are reversibly crosslinked to each other and/or modified with functional groups and protected from protease degradation by a polymer-based or silica-based nanoshell.

Abstract: The present disclosure provides a synthetic nanoparticle comprising a peptide nucleic acid (PNA) oligomer conjugated to a lipid, wherein the PNA oligomer noncovalently complexes with an immunomodulatory compound, thereby forming a nanoparticle. The nanoparticles are useful to elicit immune responses and can be used to treat a broad range of cancers and infectious diseases.

Abstract: The targeted delivery of therapeutic agents to specific cells remains a challenge in drug delivery. Provided herein are nanoparticle-targeting agent conjugates that can be used for the targeted delivery of therapeutic agents to certain cells and target tissues. The conjugates comprise nanoparticles (e.g., metal nanoparticles such as gold nanoparticles) with organic outer shells capable of adsorbing large numbers of therapeutic agents (e.g., small molecule drugs). The nanoparticles are covalently linked to targeting agents (e.g., proteins such as antibodies). The present invention also provides formulations comprising the nanoparticle-targeting agent conjugates, and kits comprising the same. In another aspect, the present invention provides methods of using the conjugates for the delivery of therapeutic agents to cells, and the treatment and/or prevention of diseases (e.g., autoimmune diseases, infectious diseases, proliferative diseases such as cancer).

Abstract: The invention provides compositions and methods for delivering agents to localized regions, tissues, or organs in vivo by conjugating agent-loaded nanoparticles to cells having homing capability.
