Following publication of the original article [1], the authors identified inadvertent errors in caption of Fig. 4.

The caption for Fig. 4 originally read:


Ultrasensitive detection of amyloid-beta-oligomers in mice CSF using a poly(3,4-ethylene dioxythiophene) (PEDOT)-embedded Au nanoelectrode. Reprinted with permission from ref. [138].


The caption for Fig. 4 should read: Figure 4 Conceptual illustration for the detection of Aβ42 using localized surface plasmon resonance (LSPR) technique. Reprinted with permission from Ref. [138]


The original article [1] has been corrected.
