Nanopartz™ Gold Nanoparticles for In Vitro Dark Field Imaging
Nanopartz™ Gold Nanoparticles for in vitro Dark Field Imaging utilize the complete line of nanospheres and nanorods for dark field microscopy from 500nm to the near IR. These conjugated particles exhibit extinctions many orders of magnitude greater than fluorophores. Every batch is completely characterized including size, monodispersity, aggregation, residual chemicals, and concentration. A Certificate of Analysis (COA) is provided for every order exhibiting TEM and UV-VIS images and data, as well as DLS data. This product comes in two concentration, 2.5mg/mL and 12.5mg/mL. The highly concentrated gold nanoparticles come in a range of conjugations.

Photomicrographs of Chlamydomonas are shown in Figure 2A-C and a buccal cell in Figure 2D. The difference in refractive indices of the media with the cell wall and other components of the algae are visualized in brightfield (Fig. 2A & B). Closing the condenser aperture diaphragm increases contrast allowing the flagella to be barely visible (Fig. 2A). Darkfield clearly shows many intracellular details as well as the flagella (Fig. 2C). Because these are unmounted living cells, they have moved a bit between the different exposures. Buccal cells are so similar in refractive index to the medium that photos of them could not be obtained in brightfield. Figure 2D shows buccal cells in darkfield; nucleus and other intracellular structures are clearly visible. Samples were photographed using CH2 student-grade Olympus microscope with 40X objective and 3.3X photo eyepiece on Kodak TMAX 400 film. |
This diagram compares the essential components of brightfield and darkfield microscopy. The difference in illumination (shown by stippling) of the sample between brightfield and darkfield is emphasized in the diagram. Darkfield utilizes a darkfield "stop" illustrated by the "spider stop" placed below the condenser. This stop blocks the center of the beam of light to produce a hollow cone of light. This light does not directly enter the objective lens. In contrast, a solid cone of light illuminates and enters the objective lens in brightfield. Only light that is scattered by the sample (depicted by the lines in the diagram) and enters the objective lens is seen as an image in darkfield. |
