Transmission electron microscopy for imaging live cells

摘要

In one aspect, the present invention relates to a microfluidic chamber. In one embodiment, the microfluidic chamber has a first sub-chamber and at least one second sub-chamber. The first sub-chamber has a first window and a second window. Both the first window and the second window are transparent to electrons of certain energies. The second window is positioned substantially parallel and opposite to the first window defining a first volume therebetween. The first window and the second window are separated by a distance that is sufficiently small such that an electron beam that enters from the first window can propagate through the first sub-chamber and exit from the second window. The at least one second sub-chamber is in fluid communication with the first sub-chamber and has a second volume that is greater than the first volume of the first sub-chamber.

主权项

1. A microfluidic chamber comprising:
(a) a first sub-chamber comprising a first window and a second window that is positioned substantially parallel and opposite to the first window defining a first volume therebetween;
wherein each of the first window and the second window is transparent to electrons of certain energies, and the first window and the second window are separated by a distance such that an electron beam that enters from the first window can propagate through the first sub-chamber and exit from the second window, wherein the distance between the first window and the second window is smaller than about 1 micron; and (b) at least one second sub-chamber that is in fluid communication with the first sub-chamber, wherein the at least one second sub-chamber has a second volume that is greater than the first volume of the first sub-chamber.
