Abstract

Безопасный медицинский порошок с превосходными характеристиками, который представляет собой магниточувствительный порошок для диагностики, терапии или раздачи лекарств и который, даже если находится в организме в течение длительного периода времени, не страдает уменьшением магнитной чувствительности и не высвобождает ионы и так далее. Медицинский порошок содержит базовую частицу из ферромагнитного материала со слоем покрытия на ней, в котором, по меньшей мере, наружная сторона слоя покрытия содержит биоинертное вещество. Слой покрытия, содержащий биоинертное вещество, предпочтительно включает в себя слой, содержащий продукт гидролиза алкоксидного соединения.Международная заявка была опубликована вместе с отчетом о международном поиске.
