Abstract: Изобретение относится к устройству и способу для анализа частиц и формирования изображения частиц или клеток во флюидах, и в частности к устройству и способу формирования изображения частиц во флюидах при использовании давления, динамики флюида, электрокинетических и оптических сил. Предлагается конфигурация микрофлюидного чипа, в которой нагнетание происходит кверху в вертикальном направлении, а резервуары с флюидом расположены под чипом для минимизации осаждения частиц перед участком анализа и на участке анализа каналов чипа. Согласно одному аспекту ввод и протекание флюида кверху через нижнюю часть чипа осуществляются при использовании манифольда, что исключает ортогональную переориентацию динамики флюида. Содержимое пробирок расположено под чипом и закачивается кверху и вертикально непосредственно в первый канал чипа. Длинный канал продолжается от нижней части чипа почти до верхней части чипа, где он сменяется коротким горизонтальным. Флюид закачивается кверху на горизонтальный участок анализа, который представляет собой самый верхний канал/самое верхнее место нахождения флюида в чипе и поэтому находится вблизи верхней части чипа, следствием чего является формирование более ясного изображения. 5 н. и 91 з.п. ф-лы, 9 ил.
