摘要：

Carbon nanotubes (CNTs) did not exhibit strong interactions with Biliverdin \Xbeta reductase enzyme (BVRB) in water. With the use of noncovalent functionalization by the surfactant Triton X-100, the surfaces of the CNTs were changed from hydrophobic to hydrophilic. The hydrophilic surface of the CNT-Triton conjugate interacts with the hydrophilic surface of BVRB, thus creating a water-soluble complex. Results from ultracentrifugation through a sucrose gradient and gel electrophoresis show the presence of the enzyme. Raman spectroscopy confirmed that the enzyme indeed interacts with CNT-Triton conjugates.
