In a recent publication , Cheng et al. argued that a waveguide (WG) coated with gold nanoparticles (NPs) should have an improved sensitivity over traditional surface plasmon resonance biosensors. Although the qualitative results of the study regarding the improvement in sensitivity are correct, errors in the numerical calculations resulted in several figures reporting incorrectly scaled values.
The corrected numerical values are as follows: the axis in Fig. 5 must be reduced by a factor of 29. The axes in Figs. 6 and 11 should be reduced by a factor of 29.5. The corrected versions of Figs. 7 and 9(b) are shown as Figs. 1 and 2.
The authors would like to thank students Iterio Degli-Eredi and Daniel-Anthony Travo for discussions and calculations leading to the corrected results.
