Abstract
1. Сигаретный фильтр, содержащий: ! пучок волокон, через который проходит дым сигареты; ! тонкий порошок с высокой площадью поверхности, примешанный в пучок волокон фильтра так, что порошок в нем распределен; и ! молекулу двухнитевой ДНК, прикрепленную к внешней поверхности тонкого порошка с высокой площадью поверхности, ! причем вредные вещества, такие как бензо[а]пирен, содержащиеся в дыме сигареты, улавливаются интеркалированием в молекулу двухнитевой ДНК для их удаления. ! 2. Сигаретный фильтр по п.1, в котором тонкий порошок с высокой площадью поверхности образован из гранулированной целлюлозы. ! 3. Сигаретный фильтр по п.1, в котором средний размер частиц тонкого порошка с высокой площадью поверхности составляет от 50 до 2000 мкм. ! 4. Сигаретный фильтр по п.1, в котором средний размер частиц тонкого порошка с высокой площадью поверхности составляет от 300 до 800 мкм. ! 5. Сигаретный фильтр по любому из пп.1-4, содержащий тонкий порошок с высокой площадью поверхности в количестве от 1 до 50 вес.% и молекулы двухнитевой ДНК в количестве от 0,01 до 10 вес.% от веса пучка волокон фильтра. ! 6. Сигарета, обернутая в бумагу, снабженная сигаретным фильтром по любому из пп.1-5.1. A cigarette filter containing:! a bundle of fibers through which cigarette smoke passes; ! fine powder with a high surface area, mixed into a bundle of filter fibers so that the powder is distributed in it; and! a double-stranded DNA molecule attached to the outer surface of a fine powder with a high surface area,! and harmful substances such as benzo [a] pyrene contained in the smoke of a cigarette are captured by intercalation in a double-stranded DNA molecule to remove them. ! 2. The cigarette filter according to claim 1, in which a fine powder with a high surface area is formed from granulated cellulose. ! 3. The cigarette filter according to claim 1, in which the average particle size of the fine powder with a high surface area is from 50 to 2000 microns. ! 4. The cigarette filter according to claim 1, in which the average particle size of the fine powder with a high surface area is from 300 to 800 microns. ! 5. A cigarette filter according to any one of claims 1 to 4, containing a fine powder with a high surface area in an amount of from 1 to 50 wt.% And a double-stranded DNA molecule in an amount of from 0.01 to 10 wt.% Of the weight of the filter fiber bundle. ! 6. A cigarette wrapped in paper equipped with a cigarette filter according to any one of claims 1 to 5.
