freeze-etching
замораживание-травление
Метод приготовления материала для электронной микроскопии, включает замораживание свежей или фиксированной ткани во фреоне или жидком азоте и изготовление срезов в условиях вакуума, при котором происходит частичная сублимация воды из ткани и на ее поверхности проступает рельеф, с такой травленной поверхности получают отпечатки и исследуют их под электронным микроскопом; метод позволяет получать трехмерное изображние объекта.
