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.

Shelf Life/Storage Temperature

This product is guaranteed for six months and should be stored at 4°C after opening. Care must be taken to only use sterile glassware when working with this product.

Sterilization/Endotoxin

Sterilization and Endoxtoin Free Options are available.

Certifications

This product is manufactured using our audited ISO 9000/2001 quality control system. Every order comes with a Certification of Analysis. We use NIST traceable:

UV-VIS (Agilent 8453) for extinction and concentration measurements

NIR (Cary 500) for NIR extinction and concentration measurements

DLS (Malvern Nano ZS) for zeta potential measurement

ICP-MS (Varian 820-MS) for gold mass measurements

TEM (Phillips CM-100 100KV) for sizing

These gold nanoparticles exhibit extinctions from 500nm to 2100nm, perfect for labeling in dark field microscopy applications. These gold nanoparticles come with a wide variety of covalent conjugations, specifically suited for in-vitro applications. They are resistant to high salt concentrations, and a wide variety of pHs (4-9). The customer is given the opportunity to select from a variety of buffers, and may request custom conjugations to specific antibodies. Nanopartz possesses technologies that allow for the "site specific conjugation" to antibodies, thereby keeping the ligand active for further activity. Customer has a choice for radiation sterilization (no sodium azide is used) certification and endotoxin free products.

Spherical Gold UV VIS Gold Nanorods UV VIS

 

 

Spherical Gold UV VIS

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.

Gold Nanorods UV VIS

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.

 

 

 

"We have looked at many different gold nanoparticles samples from Nanopartz including spheres, rods, and microrods using single particle spectroscopy techniques and are extremely happy with the quality of the samples and the service provided by Nanopartz."
