Nanopartz™ Ntracker™ for in vivo Therapeutics

Nanopartz™ Ntracker™ for in vivo therapeutics are gold nanorods specifically for use in in vivo applications such as cancer therapy research. These nanorods are coated in a proprietary dense layer of hydrophilic polymers that shield the gold surface and give the particles ultra-long circulation times. The combination of the highly monodisperse gold nanorods with the dense polymer coating extend circulation times 50% longer than other commercial polymers. As opposed to other commercially available nanoparticles such as quantum dots, Ntracker™ nanorods are completely non-toxic. Taking advantage of Enhanced Permeability and Retention effect (EPR), passive tumor targeting is possible where preclinical studies have shown ~7%ID/g tumor accumulation in mice 72 hours post injection, and better in companion animals. This product comes in a diameter of 10nm with SPRs matching all of the popular Near IR CW laser wavelengths, 780, 808, 850, 980, and 1064nm. Every batch is radiation sterilized in PBS, and comes with instructions. A Certificate of Analysis (COA) is provided for every order exhibiting TEM and UV-VIS images and data, as well as DLS data. Every product is in stock (99%) and is shipped same day. This product comes in two concentrations, regular OD=50, and highly concentrated OD=250.

Shallow-tissue modalities

Optical coherence tomography (OCT) [ref]

OCT captures three-dimensional images from optical scattering media (e.g., biological tissue), and it sometimes can provide sub-micrometer resolution. However, the imaging depth in OCT is limited by optical scattering rather than absorption because scattering tends to attenuate and randomize the light. Depending on the wavelength of light, this technique can achieve imaging depths of up to 2 mm in most tissues. This technique has been used clinically for some applications such as eye examination and has been tested in vivo and ex vivo for cancer diagnosis. In order to generate sufficient contrast, the imaging agents for this modality need to have large scattering cross sections.

Photoacoustic tomography (PAT) [ref]

PAT is a hybrid imaging modality that provides strong optical absorption contrast and high ultrasonic resolution. Because the spatial resolution beyond one optical transport mean free path (~1 mm) is determined by ultrasonic parameters, the maximum imaging depth and resolution of PAT are scalable when diffusive photons are available. One can greatly increase the penetration depth of PAT with near-infrared light because the optical absorption of hemoglobin and scattering of tissues are weak in this regime. Therefore, a proper combination of PAT with the right contrast agent can accurately detect and diagnose tumors. As in the case of OCT, the imaging depth depends on the wavelength of light, but the imaging depth (~30 mm) is higher than OCT. This modality is currently being evaluated in vivo. Additionally, contrast agents for PAT need to have large absorption cross sections.

Two-photon microscopy [ref]

Two-photon microscopy is a fluorescence-based technique that offers images of living tissue up to ~1 mm in depth. It usually uses red-shifted light to minimize scattering in the tissue, and the background signal is strongly suppressed owing to multiphoton absorption. It is being tested in vivo. Recently, Nguyen and colleagues reported that surgery with molecular fluorescence imaging can be efficient for complete removal of tumors [ref]. The results might suggest a breakthrough in the application of two-photon microscopy for molecular imaging to overcome the disadvantage of imaging depth.

Surface-enhanced Raman spectroscopy (SERS) imaging [ref]

SERS utilizes the enhancement of Raman scattering by molecules adsorbed on surfaces of metal NPs. The increment can be as much as 10^14–10^15, hence Raman-active dyes placed on the surface of gold and silver colloids will exhibit greatly amplified Raman signals. The ability of gold colloids to easily conjugate with targeting ligands enables the detection of tumors in vivo using this technique [refref].
