  • Publication number: 20230404933
    Abstract: The present disclosure generally relates to a composition matter and a method for cancer treatment. In particular, a composition of soft, non-cationic nanocapsules, termed Nanosac, for systemic delivery of siRNA. Nanosac is produced by sequential attachment of siRNA and polydopamine on a sacrificial MSN core, followed by removal of the MSN. Encapsulating siRNA in the capsules, Nanosac avoids the issues common to cationic gene carriers, such as toxicity and non-specific protein binding while protecting siRNA from RNase. Nanosac entered tumor cells by caveolae-mediated endocytosis, likely via albumin recruited from serum, trafficked to the cytosol, and silenced target genes.

  • Patent number: 11793982
    Abstract: Drug delivery devices that have a flexible film, an array of nanoscopic, porous needles attached to a surface of the flexible film, and a therapeutic drug cargo loaded onto the needles. The drug delivery device may be applied to living tissue such that the surface of the flexible film contacts the living tissue and some or all of the needles are inserted into the tissue. The flexible film may then be dissolved while leaving the needles inserted in the tissue. The needles degrade in the living tissue over time causing release of the therapeutic drug cargo loaded onto the needles.

  • Publication number: 20220401374
    Abstract: The present disclosure generally relates to a composition matter and a method for cancer treatment comprising albumin (alb) coated tannic acid-Fe nanoparticles (NPs) with a therapeutic compound, and one or more diluents, excipients or carriers. In particular, the present invention provides a treatment by enhancing antitumor immunity using tannic acid-based nanoparticles containing a therapeutic cancer treatment that can induce immunogenic cell death (ICD). The method disclosed herein provides a potential solution to the immunotoxicity accompanying the ICD cancer immunotherapy by intratumoral or intravenous administration of a nanocapsule formulation of carfilzomib (CFZ), an ICD-inducing proteasome inhibitor, using interfacial supramolecular assembly of tannic acid (TA) and iron, supplemented with albumin coating for better metabolic stability.
