Enzyme Structure: A) Far-UV CD spectra of pristine GOx. B) Changes in the secondary structure of GOx following ultrasonication for 5 and 60 min compared to pristine GOX (0 min). * p < 0.05. C) Changes in the secondary structure of GOx-SWNT-X-L. Among the three parameters of interest, length of SWNT had the greatest effect on structure compared to functionality and sonication time. * p < 0.05.
