摘要：

Wrapped around the finger: A hybrid-type biocatalyst suitable for extreme conditions is engineered by immobilizing cellulase on DNA-wrapped single-walled carbon nanotubes (SWNTs). The exocellulases are attached to the bare surface of the nanotubes, which are helically wrapped with DNA. Such spatially hybridized cellulases on DNA-dispersed individual SWNTs are stable in alkaline conditions and at high temperatures and exhibit a high initial enzymatic activity.
