“…Additionally, SWCNT with no surfactant and not centrifuged showed no clear nanotube absorbance or fluorescence emission peaks, indicating that surfactant suspension and centrifugation remove most bundled SWCNT and most amorphous carbon. Based on an integrated fluorescence emission spectrum, the sample of mixed chirality was composed of largely (6,5), (8,4), and (7,5) SWCNTs, as is expected with CoMoCat SWCNT (Figure 1(e)). The DNA:SWCNT sample had an average SWCNT diameter of 0.83 nm, ranging from 0.6 to 1.4 nm (Figure 1(g)).…”

“…The DNA:SWCNT sample had an average SWCNT diameter of 0.83 nm, ranging from 0.6 to 1.4 nm (Figure 1(g)). The integrated fluorescence emission spectrum of this sample showed a majority of SWCNTs being of (6,5), (8,4), (7,5), (6,4), and (7,3) chirality (Figure 1(f)). The SC:SWCNT sample had an average diameter of 0.864 nm, with SWCNT being in the same range as DNA:SWCNT (Figure 1(h)).…”

Increasing use of single-walled carbon nanotubes (SWCNTs) will lead to their increased release into the environment. Previous work has shown negative effects of SWCNT on growth and survival of model organisms. The aim of the current study was to determine the effect of SWCNT well-dispersed by either DNA or sodium cholate (SC) on the unicellular green algae Chlamydomonas reinhardtii in stagnant water conditions. Growth measurements were taken up to ten days for algae treated with varied levels of DNA:SWCNT or SC:SWCNT or controls, and chlorophyll content after 10 days was determined. Results show no effect on either growth or chlorophyll content of algae at any concentration or duration. This is in contradiction to prior work showing toxicity of SWCNT to environmental model organisms.

“…The near-infrared photoluminescence intrinsic to the semiconducting single-walled carbon nanotubes (SWNTs) is ideal for biological imaging through the low autofluorescence and deep tissue penetration in the near-infrared region beyond 1 µm [143]. Their NIR fluorescence also offers a powerful approach for sensor development and in vivo or real-time imaging of biological systems [144]. They present an emission in the second IR window (1000-1350 nm), which would enable even deeper light penetration.…”

The successful development of nanomaterials illustrates the considerable interest in the development of new molecular probes for medical diagnosis and imaging. Substantial progress was made in synthesis protocol and characterization of these materials whereas toxicological issues are sometimes incomplete. Nanoparticle-based contrast agents tend to become efficient tools for enhancing medical diagnostics and surgery for a wide range of 2 imaging modalities. Multimodal nanoparticles (NPs) are much more efficient than conventional molecular-scale contrast agents. They provide new abilities for in vivo detection and enhanced targeting efficiencies through longer circulation times, designed clearance pathways, and multiple binding capacities. Properly protected, they can safely be used for the fabrication of various functional systems with targeting properties, reduced toxicity and proper removal from the body. This review mainly describes the advances in the development of mono-to multimodal NPs and their in vitro and in vivo relevant biomedical applications ranging from imaging and tracking to cancer treatment. Besides specific applications for classical imaging, (MRI, PET, CT, US, PAI) are also mentioned less common imaging techniques such as terahertz molecular imaging (THMI) or ion beam analysis (IBA).Perspectives on multimodal theranostic NPs and their potential for clinical advances are also mentioned.

This review mainly describes the advances in the development of mono-to multimodal NPs and their in vitro and in vivo relevant biomedical applications ranging from imaging and tracking to cancer treatment. Besides the specific applications for classical imaging (magnetic resonance imaging, positron emission tomography, computed tomography, ultrasound, and photoacoustic imaging), the less common imaging techniques such as terahertz molecular imaging (THMI) or ion beam analysis (IBA) are mentioned. The perspectives on the multimodal theranostic NPs and their potential for clinical advances are also mentioned.
