  • Publication number: 20130329215
    Abstract: One aspect of the invention provides a nanothin polymer film having a plurality of pores defined solely by polymers of the polymer film. The pores have a uniform size. Another aspect of the invention provides a method of using a polymer film capsule with pores defined solely by the film described herein. The method includes: separating a mixture of chemicals having variable surface areas from the polymer film capsule by using a size exclusion column; collecting the polymer film capsule eluate from the size exclusion column; and determining a content of chemicals retained in the polymer film capsule by using UV/vis spectroscopy.

  • Patent number: 8519015
    Abstract: A method of preparing nanothin polymer films having uniform and selectively sized pores utilizing pore forming templates. Lipids and pore forming templates are dissolved into a first solution. The solvent is removed thereby creating a lipid bilayer with pore forming templates dispersed throughout. The bilayer is hydrated and monomers and crosslinkers are added to create a second solution. A nanothin film with pore forming templates is created through polymerization of said second solution. The pore forming templates are dissolved into a third solution by addition of a chemical in which the pore forming template is soluble, but the lipid bilayer is insoluble. This third solution is separated from the mixture leaving a nanothin polymer film with pores of a uniform thickness and surface area.

  • Patent number: 7829155
    Abstract: The present invention provides a new monomer and methods of using the monomer to fabricate robust polymer surface coatings with controlled thicknesses between 1 and 5 nanometers. The coatings are composed of a new material containing polymerized monomers of 4-vinylbenzenepropanethiol. The polymer surface coating may be applied to metal and silicon. The method includes exposing a metal substrate to a solution of the monomer in hexanes in order to deposit a monolayer of the monomer onto the metal surface. The substrate is then irradiated with ultraviolet radiation in order to graft a thin polymer coating onto the surface. The procedure can be repeated in order to control the thickness of the coating between about 1 nm and 5 nm. Alternatively, thermally initiated polymerization or deposition of partially oligomerized monomers onto the surface provides nanothin coatings with identical performance.

  • Publication number: 20100178326
    Abstract: A novel class of carriers for liposome-based drug delivery and release systems is provided. Such carriers exhibit excellent compatibility with hydrophilic drug compounds as well as effective release upon transport through phospholipid bilayers of cell membranes. Furthermore, such carriers are non-cytotoxic, particularly in terms of contact with cell membranes themselves. As such, these carriers accord an excellent manner of transporting pharmaceutical and other like compounds and materials to a user's individual cells for delayed release thereof at the site necessary to effectuate proper treatment. Drug delivery materials including such carriers are encompassed within this invention, as well as the overall method of drug delivery and delayed release provided thereby.
