Patents by Inventor Stephany Y. Tzeng

Stephany Y. Tzeng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20210252154
    Abstract: Degradable polymers were synthesized that self-assemble with DNA to form particles that are effective for gene delivery. Small changes to polymer synthesis conditions, particle formulation conditions, and polymer structure provides significant changes to efficacy in a cell-type dependent manner. Polymers presented here are more effective than commercially available materials, such as LIPOFECTAMINE 2000™, FUGENE®, or polyethylenimine (PEI), for gene delivery to cancerous fibroblasts or human primary fibroblasts. The presently disclosed materials may be useful for cancer therapeutics and regenerative medicine.

  • Publication number: 20110250284
    Abstract: The invention relates to synthetic platelet compositions and methods useful in diminishing bleeding and blood loss. The synthetic platelets of the invention can comprise a biocompatible, biodegradable polymer, including, for example, a poly(lactic-co-glycolic acid)-poly-L-lysine (PLGA-PLL) block copolymer, having conjugated PEG arms terminating with RGD motif containing peptides. The invention further comprises compositions and methods useful in the delivery of therapeutic agents.
