Uniform, functional polymer patches can be attached to a fraction of the surface area of living individual cells. These surface-modified cells can cross the blood-brain barrier while remaining viable after attachment of the functional patch. Functional payloads carried by the patch can include a drug. The patch can include one or more polyelectrolyte multilayers (PEMs).

A simple spray coating process can be utilized to create epoxy/HNT nanocomposites with vertically aligned nanotubes. Important mechanical properties such as modulus and hardness values can be optimized and enhanced by controlling the level of nanotube dispersion during processing and the final orientation of the nanotubes. Thus, a technologically relevant processing scheme can be used to fabricate HNT nanocomposites with a high level of control over nanotube alignment and the resulting mechanical properties.

Spray-coating method with particle alignment control

Titania-based porous nanoparticle coatings are mechanically robust, with low haze, which exhibit short time scales for decomposition of fingerprint oils under ultraviolet light. The mechanism by which a typical dactylogram is consumed combines wicking of the sebum into the nanoporous titania structure followed by photocatalytic degradation. These TiOnanostructured surfaces are also anti-fogging, anti-bacterial, and compatible with flexible glass substrates and remain photocatalytically active in natural sunlight.

A superhydrophilic coating on a substrate can be antireflective and antifogging. The coating can remain antireflective and antifogging for extended periods. The coating can include oppositely charge inorganic nanoparticles, and can be substantially free of an organic polymer. The coating can be made mechanically robust by a hydrothermal calcination.

Superhydrophilic coatings

A microfluidic device for manipulating particles can include a substrate and one or more obstacles, each obstacle comprising a plurality of aligned nanostructures including a plurality of nanoparticles or a plurality of polymer layers, or a combination thereof. The obstacle on a substrate can be forests with intra-carbon nanotube spacing ranging between 5-100 nm for isolation of particles such as very small viruses and proteins.

An optical article comprising a substrate and on at least one face of the substrate a multilayered antireflecting coating functioning in an interferential manner having antifog properties, said antireflecting coating including a last layer with a refractive index n&#x2266;1.55 and a physical thickness of 120 nm or less directly deposited on a high refractive index layer (HI layer) having a refractive index n&#x3e;1.55, and a thickness of less than 500 nm.

A superhydrophilic thin film is formed on a metal surface of a boiler vessel to alter the wettability and roughness of the surface, which, in turn, changes the boiling behavior at the surface. The superhydrophilic film is formed by depositing a layer of a first ionic species on the surface from a solution. A second ionic species having a charge opposite to the that of the first ionic species is then deposited from solution onto the surface to produce a bilayer of the first ionic species and the oppositely charged second ionic species. The depositions are then repeated to form a plurality of bilayers, on top of the preceding bilayer. The bilayers are then heated, leaving the second ionic species on the metal surface to form a superhydrophilic film.

The present invention discloses a non-quarter wave multilayer structure having a plurality of alternating low index of refraction material stacks and high index of refraction material stacks. The plurality of alternating stacks can reflect electromagnetic radiation in the ultraviolet region and a narrow band of electromagnetic radiation in the visible region. The non-quarter wave multilayer structure, i.e. nd&#x2260;nd&#x2260;&#x3bb;/4, can be expressed as [A 0.5 qH pL(qH pL)0.5 qH G], where q and p are multipliers to the quarter-wave thicknesses of high and low refractive index material, respectively, H is the quarter-wave thickness of the high refracting index material; L is the quarter-wave thickness of the low refracting index material; N represents the total number of layers between bounding half layers of high index of refraction material (0.5 qH); G represents a substrate and A represents air.

Uniform, functional polymer patches can be attached to a fraction of the surface area of living individual cells. These surface-modified cells remain viable after attachment of the functional patch. The patch does not completely occlude the cellular surface from the surrounding environment. Functional payloads carried by the patch may include, for example, drugs or other small molecules, peptides, proteins, thermally responsive polymers, and nanoparticles, or any other material that can be incorporated in a polymer patch of subcellular dimensions. The patch can include one or more polyelectrolyte multilayers (PEMs).

The atomizing nozzle is used to spray a plurality of first nanoparticle solution layers, the plurality of first nanoparticle layers forming a low index of refraction stack. In some instances, a polymer solution can be sprayed before and/or after the spraying of each first nanoparticle solution layer. The atomizing nozzle is also used to spray a plurality of second nanoparticle solution layers, the plurality of second nanoparticle layers form a high index of refraction stack. Similar to the first nanoparticle solution layers, a polymer solution can be sprayed before and/or after the spraying of each second nanoparticle solution layer.
