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

CoMoCAT™ Catalytic Chemical Vapor Deposition (CVD) Method

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
