    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.

  • Patent number: 11285211
    Abstract: It has been discovered that iron-platinum ferromagnetic particles can be dispersed in a polymer and coated into or onto, or directly linked to or embedded on to, medical devices and magnetized. The magnetized devices are used to attract, capture, and/or retain magnetically labeled cells on the surface of the device in vivo. The magnetic particles have an iron/platinum core. Annealing the Fe/Pt particle is very important for introducing a L10 interior crystalline phase. The Fe:Pt molar ratio for creation of the crystal phase is important and a molar range of 1.2-3.0 Fe to Pt (molar precursors, i.e. starting compounds) is desired for magnetization. The magnetic force as a whole can be measured with a “Super Conducting Quantum Interference Device”, which is a sensitive magnetometer. The overall magnetic force is in the range from 0.1 to 2.0 Tesla.
