  • 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.
