A quasi-soft catcher, a quasi-soft capture device, and a method for using the same are provided. The quasi-soft catcher includes a base and a plurality of protruding structures for capturing at least one target biological particle from a specimen. The protruding structures are regularly arranged on a board surface of the base. Each of the protruding structures includes an outer portion configured to touch the at least one target biological particle and an inner portion that is connected between the board surface and the outer portion, and a structural strength of the inner portion is less than that of the outer portion. The board surface has an interspace region arranged outside of the protruding portions, and the interspace region occupies 20-80% of the board surface.

Quasi-soft catcher, quasi-soft capture device, and method using the same

A microfluidic device includes a lower casing and an upper casing covering the lower casing. The lower casing includes a lower base wall having a top surface and a plurality of spaced-apart columns that protrude upwards from the top surface. The upper casing includes an upper base wall. A first gap between the upper base wall and a column top surface of each of the columns is large enough to permit passage of large biological particles of a liquid sample, and a second gap between any two adjacent ones of the columns is not large enough to permit passage of the large biological particles and is large enough to permit passage of small biological particles of the liquid sample.

Microfluidic device

A catcher, a capture device, and a method for capturing at least one target biological particle are provided. The catcher includes a base and a plurality of capture arms extending from the base and spaced apart from each other. Each of the capture arms has a free end portion configured to capture a target biological particle and a supporting segment connected between the free end portion and the base. The supporting segment of each of the capture arms is arranged in a projection space defined by orthogonally projecting the free end portion along a height direction onto the base. When the target biological particle is captured by two of the capture arms that are bent and arranged adjacent to each other, a part of the target biological particle is trapped by the supporting segments of the two of the capture arms and is held.
