    Abstract: The present invention is directed to protocells for specific targeting of hepatocellular and other cancer cells which comprise a nanoporous silica core with a supported lipid bilayer; at least one agent which facilitates cancer cell death (such as a traditional small molecule, a macromolecular cargo (e.g. siRNA or a protein toxin such as ricin toxin A-chain or diphtheria toxin A-chain) and/or a histone-packaged plasmid DNA disposed within the nanoporous silica core (preferably supercoiled in order to more efficiently package the DNA into protocells) which is optionally modified with a nuclear localization sequence to assist in localizing protocells within the nucleus of the cancer cell and the ability to express peptides involved in therapy (apoptosis/cell death) of the cancer cell or as a reporter, a targeting peptide which targets cancer cells in tissue to be treated such that binding of the protocell to the targeted cells is specific and enhanced and a fusogenic peptide that promotes endosomal escape of protocells and encapsulated DNA. Protocells according to the present invention may be used to treat cancer, especially including hepatocellular (liver) cancer using novel binding peptides (c-MET peptides) which selectively bind to hepatocellular tissue or to function in diagnosis of cancer, including cancer treatment and drug discovery.

    Abstract: The present invention is directed to the use of silicic acid to transform biological materials, including cellular architecture into inorganic materials to provide biocomposites (nanomaterials) with stabilized structure and function. In the present invention, there has been discovered a means to stabilize the structure and function of biological materials, including cells, biomolecules, peptides, proteins (especially including enzymes), lipids, lipid vesicles, polysaccharides, cytoskeletal filaments, tissue and organs with silicic acid such that these materials may be used as biocomposites. In many instances, these materials retain their original biological activity and may be used in harsh conditions which would otherwise destroy the integrity of the biological material. In certain instances, these biomaterials may be storage stable for long periods of time and reconstituted after storage to return the biological material back to its original form. In addition, by exposing an entire cell to form CSCs, the CSCs may function to provide a unique system to study enzymes or a cascade of enzymes which are otherwise unavailable.

    Abstract translation: 本发明涉及使用硅酸将生物材料（包括细胞结构）转化为无机材料以提供具有稳定结构和功能的生物复合材料（纳米材料）。 在本发明中，已经发现了稳定生物材料的结构和功能的手段，包括细胞，生物分子，肽，蛋白质（特别是酶），脂质，脂质囊泡，多糖，细胞骨架细丝，组织和器官与硅 酸，使得这些材料可以用作生物复合材料。 在许多情况下，这些材料保留其原始生物活性，并且可以在恶劣条件下使用，否则会破坏生物材料的完整性。 在某些情况下，这些生物材料可能长时间保持稳定，并在储存后重构，以将生物材料返回其原始形式。 此外，通过暴露整个细胞以形成CSCs，CSC可以起到提供独特的系统来研究否则不可用的酶或级联的酶。
