Abstract: Particles with a spatial and/or temporal release profile for delivery of different agents at different times to the same cells of a subject have been developed. The particles include a core polymeric particle containing a polymer and a first agent, a tethering moiety, covalent linker or covalent linkage attached to the core particle, and a tethered particle attached to the particle via the tethering moiety, covalent linker or covalent linkage and containing a second agent, where the agents are released at different times within or to the same cells. The first and second agents may be a therapeutic or prophylactic agent, such as an antigen, an immunomodulator, an anti-neoplastic agent, a hormone, an inhibitor, etc. The particles may form compositions for treating diseases with a spatial and/or temporal treatment regimen.
