IMPROVED METHOD FOR PLASMA IMMOBILIZATION OF A BIOMOLECULE TO A SUBSTRATE VIA A LINKING MOLECULE

Номер: CA3119680A1
Принадлежит:

The current invention relates to a two step method for the immobilization of a biomolecule through a linking molecule on a sample surface of a substrate by generating and maintaining a non-thermal atmospheric pressure plasma at a temperature between room temperature and 60°C. The preferred plasma temperature is room temperature. The method comprises of a first step and second step, which are sequentially carried out. In the first step of the method, the linking molecule is deposited onto the sample surface through exposing the sample surface to a first plasma jet and the linking molecule, generating a linking layer onto the sample surface. In a second sequential step of the method, the biomolecule is deposited onto the linking layer through exposing the linking layer to a second plasma jet and the biomolecule.

SOFT PLASMA POLYMERIZATION PROCESS FOR A MECHANICALLY DURABLE SUPERHYDROPHOBIC NANOSTRUCTURED COATING

Номер: CA0003072686A1
Принадлежит: SMART & BIGGAR LLP

A method for depositing a coating on a substrate is disclosed. A first precursor comprising fluoro-acrylate monomers, fluoro-alkyl acrylate monomers, fluoro- methacrylate monomers, fluoro-alkyl methacrylate monomers, fluoro-silane monomers, or a combination or derivates thereof is provided. A second precursor comprising linear siloxanes, silane monomers, cyclosiloxanes, cyclosilane monomers, or a combination or derivates thereof is provided. The first and second precursors are co-injected in a treatment region. An atmospheric or reduced pressure plasma discharge is created in said treatment region. The substrate coating comprises alternated multi-stacked nanostructures and is formed by copolymerization of the first and second precursors.

IMPROVED METHOD AND APPARATUS FOR ATMOSPHERIC PRESSURE PLASMA JET COATING DEPOSITION ON A SUBSTRATE

Номер: CA3104812A1
Принадлежит:

The current invention concerns a method for plasma coating an object comprising an object profile, comprising the steps of:a) manufacturing a replaceable shield (2) comprising a jet inlet (22), a nozzle outlet (24) and a sidewall (21) extending from the jet inlet to the nozzle outlet, wherein the nozzle outlet comprises an edge (25) essentially congruent to at least part of the object profile; b) detachably attaching the replaceable shield to a jet outlet of a plasma jet generator; c) placing the object at the nozzle outlet such that the object profile fits closely to the nozzle outlet edge, thereby minimizing a gap between the nozzle outlet and the object; d) plasma coating the object with a low-temperature, oxygen-free plasma at an operating pressure which is higher than the atmospheric pressure, preferably by at most 10%, by providing a plasma jet in the shield via the plasma jet generator and injecting coating precursors in the plasma jet in the shield, thereby creating said operating ...
