  • Patent number: 10874621
    Abstract: Nanoparticles containing an aqueous core containing one or more nucleic acids, such as siRNA, and a shell containing one or more hydrophobic cationic materials, one or more amphiphilic materials, and one or more therapeutic, diagnostic, and/or prophylactic agents are. The hydrophobic cationic material and the hydrophobic portion of the amphiphilic material provide a non-polar polymer matrix for loading non-polar drugs, protect and promoting siRNA molecule retention inside the NP core, and control drug release. The hydrophilic portion of the amphiphilic material can form a corona around the particle which prolongs circulation of the particles in the blood stream and decreases uptake by the RES.

  • Publication number: 20190329221
    Abstract: The present disclosure belongs to the technical field of analytical chemistry, in particular to synthesis and application of a nanomaterial for removal of patulin (Pat). The present disclosure adopts 2-Oxin as a substitute template, AM as a functional monomer, and synthetic Fe3O4@SiO2@CS-GO magnetic nanoparticles as a carrier, for preparing a magnetic MIP specific for Pat adsorption by surface imprinting. The addition of Fe3O4 makes the finally prepared molecular imprinted adsorbent material magnetic, thereby facilitating separation of a material from a matrix, eliminating complicated operation steps such as filtration and centrifugation, and facilitating recovery of materials.

  • Patent number: 10314917
    Abstract: 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.

  • Publication number: 20170042870
    Abstract: Nanoparticles having a positive feedback delivery system include an agent specific for a target in combination with a target inducing agent. Upon administration to a subject, the targeting moiety on the nanoparticles binds to available targets in the subject. The nanoparticles release the target inducing agent and, optionally, a therapeutic agent, at the site where the nanoparticles bind the target. The inducing agent causes additional targets to be expressed. More nanoparticles bind to the additional, induced targets. By inducing additional targets to be expressed at specific regions in the subject that require treatment, more nanoparticles can bind to the targets in that specific region of interest, increasing the concentration of nanoparticles at a specific area of subject is increased.
