Single-walled carbon nanotubes as a multimodal-thermoacoustic and photoacoustic-contrast agent.
نویسندگان
چکیده
We have developed a novel carbon nanotube-based contrast agent for both thermoacoustic and photoacoustic tomography. In comparison to deionized water, single-walled carbon nanotubes exhibited more than twofold signal enhancement for thermoacoustic tomography at 3 GHz. In comparison to blood, they exhibited more than sixfold signal enhancement for photoacoustic tomography at 1064 nm wavelength. The large contrast enhancement of single-walled carbon nanotubes was further corroborated by tissue phantom imaging studies.

Carbon nanotubes as photoacoustic molecular imaging agents in living mice.
Photoacoustic imaging of living subjects offers higher spatial resolution and allows deeper tissues to be imaged compared with most optical imaging techniques. As many diseases do not exhibit a natural photoacoustic contrast, especially in their early stages, it is necessary to administer a photoacoustic contrast agent. A number of contrast agents for photoacoustic imaging have been suggested p...
متن کاملUltrahigh sensitivity carbon nanotube agents for photoacoustic molecular imaging in living mice.
Photoacoustic imaging is an emerging modality that overcomes to a great extent the resolution and depth limitations of optical imaging while maintaining relatively high-contrast. However, since many diseases will not manifest an endogenous photoacoustic contrast, it is essential to develop exogenous photoacoustic contrast agents that can target diseased tissue(s). Here we present a novel photoa...
متن کاملBroadband Spectroscopic Thermoacoustic Characterization of Single-Walled Carbon Nanotubes
Carbon nanotubes have attracted interest as contrast agents for biomedical imaging because they strongly absorb electromagnetic radiation in the optical and microwave regions. This study applies thermoacoustic (TA) imaging and spectroscopy to measure the frequency-dependent absorption profile of single-walled carbon nanotubes (SWNT) in the ranges of 2.7–3.1 GHz and 7–9GHz using two tunable micr...
متن کاملOrganometallic carbonyl clusters: a new class of contrast agents for photoacoustic cerebral vascular imaging.
We report, for the first time, the use of a water-soluble organometallic compound as a stable, reliable and high-contrast photoacoustic contrast agent. This gives a significantly higher contrast than that achievable with alternatives such as single-walled carbon nanotubes. Image enhancement of the rat cerebral cortex vasculature was observed using in vivo dark-field photoacoustic microscopy.
متن کاملSemiconducting Polymer Nanoparticles as Photoacoustic Molecular Imaging Probes in Living Mice
Photoacoustic imaging holds great promise for the visualization of physiology and pathology at the molecular level with deep tissue penetration and fine spatial resolution. To fully utilize this potential, photoacoustic molecular imaging probes have to be developed. Here, we introduce near-infrared light absorbing semiconducting polymer nanoparticles as a new class of contrast agents for photoa...
