General description

Produced using CHASM′s patented CoMoCAT^™ synthesis technology, Signis^® SG65i is a single-wall carbon nanotube (CNT) product uniquely enriched in semiconducting tubes, with (6,5) chirality being most abundant. Approximately 95% of the CNTs in SG65i are semiconducting, with approximately 41% of those tubes being (6,5) chirality.

Characterization and Biodistribution Analysis of Oxygen-Doped Single-Walled Carbon Nanotubes Used as in Vivo Fluorescence Imaging Probes.

Tsukasa Takeuchi et al.

Bioconjugate chemistry, 30(5), 1323-1330 (2019-03-09)

Single-walled carbon nanotubes (SWCNTs) show strong fluorescence in the 1000-1700 nm second near-infrared (NIR-II) wavelength range and are considered promising candidates for angiographic imaging probes. Oxygen-doped SWCNTs coated with phospholipid-polyethylene glycol (o-SWCNT-PEG) show exceptional potential, as they emit fluorescence at

Exfoliated near infrared fluorescent silicate nanosheets for (bio)photonics.

Gabriele Selvaggio et al.

Nature communications, 11(1), 1495-1495 (2020-03-22)

Imaging of complex (biological) samples in the near-infrared (NIR) is beneficial due to reduced light scattering, absorption, phototoxicity, and autofluorescence. However, there are few NIR fluorescent materials known and suitable for biomedical applications. Here we exfoliate the layered pigment CaCuSi4O10

Chirality enriched carbon nanotubes with tunable wrapping via corona phase exchange purification (CPEP).

Robert Nißler et al.

Nanoscale, 11(23), 11159-11166 (2019-06-01)

Single-walled carbon nanotubes (SWCNTs) have unique photophysical properties and serve as building blocks for biosensors, functional materials and devices. For many applications it is crucial to use chirality-pure SWCNTs, which requires sophisticated processes. Purification procedures such as wrapping by certain

Quantifying the semiconducting fraction in single-walled carbon nanotube samples through comparative atomic force and photoluminescence microscopies.

Anton V Naumov et al.

Nano letters, 9(9), 3203-3208 (2009-07-31)

A new method was used to measure the fraction of semiconducting nanotubes in various as-grown or processed single-walled carbon nanotube (SWCNT) samples. SWCNT number densities were compared in images from near-IR photoluminescence (semiconducting species) and AFM (all species) to compute

Water-ion permselectivity of narrow-diameter carbon nanotubes.

Yuhao Li et al.

Science advances, 6(38) (2020-09-18)

Carbon nanotube (CNT) pores, which mimic the structure of the aquaporin channels, support extremely high water transport rates that make them strong candidates for building artificial water channels and high-performance membranes. Here, we measure water and ion permeation through 0.8-nm-diameter
