一般描述

Single-walled carbon nanohorns are made of graphene sheets with long cone-shaped tips with the diameters of 2-5 nm and the length of 40-50 nm. Thousands of carbon nanohorns form spherical aggregates of about 100 nm in diameter.
  • Uniform size
  • High dispersion
  • High purity, no metallic compound
  • Large surface area
  • Utilization of internal space in carbon nanohorn

应用

  • Energy management system:
Capacitor (good discharge rate, high capacity)
Fuel cell (Good support materials for catalyst metal such as platinum)
  • Medical: Carrier containing the anticancer drug.
  • Gas adsorption: Adsorption of highly reactive gas.
  • Compound material: Additive for characteristic improvement (improve electrical properties).

We demonstrate that oxidized single-wall carbon nanohorns (SWNHs), a type of single-wall nanotube, entrap cisplatin, an anticancer agent. We found that the cisplatin structure was maintained inside the SWNHs and that the cisplatin was slowly released from the SWNHs in...

A novel sandwich-type electrochemical immunosensor based on functionalized nanomaterial labels and bienzyme (horseradish peroxidase and glucose oxidase) biocatalyzed precipitation was developed for the detection of α-fetoprotein (AFP). The enzymes linked to functionalized nanomaterials as biocatalysts could accelerate the oxidation of...
