Abstract:
The invention provides materials and methods for forming coatings on substrates. The coatings are durable and resistant to damage from environmental, chemical, thermal, and/or radiative sources. In some embodiments, the coatings comprise bilayers of electrostatically charged materials. The bilayers are created by alternately applying solutions comprising water-soluble, electrostatically charged materials. Durability is imparted to the coatings by the formation of crosslinks that are formed within and between layers after deposition of the coatings
Abstract:
Langmuir-Blodgett films are provided in which a molecule (30, 130) is chemically bonded with a bottom electrode (14) substrate (42) as part of a crossed wire device (10) comprising two electrodes (12, 14) and a molecular layer (16) therebetween. The molecule (30, 130), which comprises a switchable moiety (32) and a connecting moiety (34, 134), is provided with a photolabile capping group (36, 236) attached to the connecting moiety (34, 134). The photoabile capping group (36, 236) temporarily caps the reactive connecting roup (34, 134) of the molecule (30, 130). The capped molecules (30', 130', 230') are processed to form a LB film on the water-air interface (38a) of water (38). The films are then exposed to UV light. The photolabile capping group (36, 236) decomposes to give back the connecting group (34, 134), which remains in the water (38). As the uncapped LB films are transferred to the bottom electrode (14) substrate (42), the surface of the electrode reacts with the reactive connecting group (34, 134) of the molecule (30, 130) to form a chemically bonded LB layer on the substrate (42), thereby providing improved LB films.
Abstract:
The invention relates to an installation (1) for forming a compact film of particles (4) on the surface of a carrier fluid (16), comprising a zone (11) forming a carrier fluid reservoir, an inclined ramp (12), a particle accumulation and transfer zone (14), means (18) for setting the carrier fluid in motion, means (2) for dispensing the particles (4) in solution, configured to dispense the particles on the surface of the carrier fluid in the reservoir-forming zone, and a structure (50) for deflecting particles that is configured to favour, in a transverse direction (31) of the installation, a spreading of the particles (4) at the outlet of the reservoir-forming zone (11). According to the invention, the structure (50) for deflecting the particles is permeable by the carrier liquid (16).

Abstract:
The invention addressed a difficult problem in the conventional methods and has its object to provide an organic thin film with flexibility and high strength to be a support for a molecule, with which a biomolecular element or a molecule such as a membrane protein as a biosensor can function equally in a living body, and a method for producing the same. In this invention, the organic thin film to be a support for the biomolecular element or the biosensor molecule is produced by forming a layer of lipid molecules on a layer of fatty acid molecules which is a primary thin film layer formed on an inorganic substrate. Further, by the selection and combination of fatty acid molecules, a thin film structure with a characteristic pattern structure can be obtained.

A method and an apparatus (10) for making thin layers from particles, wherein the particles are deposited on a carrier fluid flowing by gravity along a ramp (12) leading to a dam (18). The particles are held back at the bottom of the ramp (12), thereby causing the particles to be piled up one against the other in a monolayer configuration.
