General description

IsoNanotubes-S^™ are produced by arch discharge or plasma torch. The diameter of the semiconducting single walled nanotubes range in 1.2-1.7 nm, whereas the length varies from 100nm to 4 μm. The degree of purity of the SWNTs can be determined from the absorbance spectrum. The optical absorbance of semiconducting SWNTs occurs at S22 (850-1250nm) and S33 (450-550nm). Toxic behavior of SWNTS were studied by studying the response of human hepatocarcinoma cells to SWNTs.

Application

These carbon nanotubes are produced via the arc discharge process and are purified via density gradient centrifugation.Semiconducting SWNTs can be used in various wearable and flexible devices such as bendable pressure sensor. Research applications include:

Electronics[1]
Sensors[2]
Composites
Energy Storage
Study of Life Science systems[3]

Single-walled carbon nanotubes (SWNTs) have been previously observed to be strong antimicrobial agents, and SWNT coatings can significantly reduce biofilm formation. However, the SWNT antimicrobial mechanism is not fully understood. Previous studies on SWNT cytotoxicity have concluded that membrane stress
