It is intended to easily separate saponins from isoflavones extracted from starting soybeans thereby giving highly pure saponins at a high yield on an industrial scale. Saponins can be highly efficiently separated from isoflavones by performing multistage extraction under mild conditions such that malonyl isoflavone glycoside, from among isoflavones contained in the starting soybeans, is not converted into isoflavone glycoside, acetyl isoflavone glycoside or isoflavone aglycon. Thus, highly pure saponins can be obtained at a high yield on an industrial scale.

Significant research is being done to develop and improve delivery mechanisms for biopharmaceuticals and vaccines, including pulmonary (inhalation), nasal, transdermal, and oral alternatives. Market projections indicate that the delivery of proteins and vaccines by inhalation and oral formulation has become and will continue to be increasingly important. These delivery mechanisms, to be effective, will require better stabilization of the biologicals so that they can maintain potency and effectiveness at ambient temperatures for extended periods of time. The novel Preservation by Vaporization (PBV) Technology described herein provides cost-effective and efficient industrial scale stabilization of proteins, viruses, bacteria, and other sensitive biologicals, thereby allowing a production of products that are not possible to be produced by existing methods. The suggested new PBV process comprises primary drying under vacuum from a partially frozen state (i.e. slush) at near subzero temperatures followed by stability drying at elevated temperatures (i.e., above 40 degrees Celsius). The new suggested method can be performed aseptically in unit doze format (in vials) and / or in bulk format (in trays, bags, or other containers). The drying can be performed as a continuous load process in a manifold vacuum dryer comprising a plurality (e.g., 30) of vacuum chambers attached to a condenser during the drying.

The present invention is generally directed to methods of functionalizing carbon nanotubes (CNTs) in acidic media. By first dispersing CNTs in an acidic medium, bundled CNTs can be separated as individual CNTs, affording exposure of the CNT sidewalls, and thereby facilitating the functionalization of such CNTs, wherein functional groups are attached to the subsequently exposed sidewalls of these individualized CNTs. Once dispersed in this substantially unhundled state, the CNTs are functionalized according to one or more of a variety of functionalization processes. Typically, ultrasonication or non-covalent wrapping is not needed to afford such dispersion and subsequent functionalization. Additionally, such methods are easily scalable and can provide for sidewall-functionalized CNTs in large, industrial-scale quantities.
