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.

Application

Suitable for use in printed semiconductors, photovoltaic devices, sensors, medical research, etc.

Preparation Note

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

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
