Embodiment 1

[0077] figure 1 A device 100 for processing fine particles to attach infectious phages thereto is shown in .

[0078] figure 1 The following parts of the device are shown in:

[0079] 101 - hopper containing fine particles deposited on the belt;

[0080] 102 - Moving belt made of conductive material or made conductive by adding a second electrode. This grinds the particles which greatly reduces or eliminates the problem of static build-up;

[0081] 103-Band barrier, which ensures that fine (monolayer) fine particles enter the corona region;

[0082] 104 - Rotating ceramic electrode which creates a corona to activate the material. The rotating electrodes allow cooling of the top surface via channel airflow;

[0083] 105 - directing air over the top of the electrodes to allow cooling;

[0084] 106 - A silicone polymer blade that isolates the feed from the air flow and scrapes the electrode surface of any particles attached;

[0085] 107 - Barriers against contact of liqu...

[0097] figure 2 and image 3 An apparatus 200 for processing fine particles to attach infectious phages thereto is shown in .

[0098] figure 2 and image 3 The following parts of the device are shown in:

[0099] 202 —Moving belt, the potential of which and of the items carried on it is controlled by means of the second / counter electrode 210 . This grinds the particles which greatly reduces or eliminates the problem of static build-up;

[0100] 204 - Rotating ceramic electrode which creates a corona to activate the material. The rotating electrode allows cooling of the top surface via channel air flow;

[0101] 205 - Cooling duct that supplies / directs air over the top of the electrodes to allow cooling;

[0102] 206 - A silicone polymer blade that isolates the feed from the air flow and scrapes the electrode surface of any particles adhering to it;

[0103] 207 - Barriers against contact of liquids with corona;

[0104] 210 - counter electrode; and

Abstract

The present invention relates to a continuous method for producing products with molecules or macromolecules attached thereto and apparatus for carrying out this method. The method comprises the steps of: (a) placing the object on or in the proximity of a surface; (b) controlling the electrical potential of the surface with respect to its surroundings; (c) activating the object by exposing it to an electrical discharge; (d) contacting the object with the molecule or macromolecule to be attached. Such macromolecules include bacteriophage. Thus products of methods of the invention are for prevention and amelioration of bacterial contamination of the product of methods of the invention or materials in contact with said products.

Description

technical field [0001] The present invention relates to methods and devices for the production of products having molecules or macromolecules attached thereto. Such macromolecules include phages. Thus, the product of the method of the invention is used to prevent and ameliorate bacterial contamination of the product of the method of the invention or of materials that come into contact with said product. Background technique [0002] Phages ("phages") are viruses that infect and replicate within bacteria. A "lytic" phage causes the bacterial cell to burst (lyse) and be destroyed after the virion has replicated within the bacterium. When cells are destroyed, phage progeny can find new hosts to infect. Phages are the most abundant form of life on Earth. Phages can be found in all environments in which bacteria grow. For example, bacteriophages have been detected in ground and surface water, soil, food (eg sauerkraut, wine), sewage and sludge. Phages have also been isolate...
