Abstract
A special purpose cuvette assembly with features that create a small, restricted volume to minimize bulk movements of liquid and that minimize backscattering of light. The special-purpose cuvette assembly enables recording of Brownian movements of nanoparticles in a liquid when it is placed in a suitable optical device comprising a light sheet and an optical microscope attached to a video camera that is oriented perpendicular to the light-sheet plane.
Claims1
A system (10) for viewing particles, the system comprising:
- a light source (15) for generating an electromagnetic energy (20) directed at a cuvette (25);
- a sensor (30) for detecting electromagnetic energy within the cuvette;
- and
- the cuvette comprising:
- exterior walls (35) and a floor (40) that define a volume (45), wherein at least a portion of the exterior walls is transparent (50) to the electromagnetic energy, and wherein the volume is adapted to contain a suspension liquid and the particles;
- a viewing chamber (55) comprising:
- an upper viewing chamber wall (60) extending from the exterior walls and a lower viewing chamber wall (65) extending from the exterior walls, wherein the upper and lower viewing chamber walls are substantially parallel to the floor;
- a reflecting wall (70) adjacent to the upper and lower viewing chamber walls;
- a backscatter chamber (75) separated from and in fluid communication with the viewing chamber (80), wherein the reflecting wall is adapted to reflect (85) the electromagnetic energy into the backscatter chamber.
