(A) left, AuNP bound to a DRG neuron to stably make the cells photosensitive for optocapacitance stimulation; right, representative traces recorded from DRG neurons labelled with primary antibodies against P2X3 receptors before and after AuNPs attachments using secondary antibodies. (B) Representative traces and peak responses over a period of time from DRG neurons from neurons labeled with primary antibodies against TRPV1 (A and C) and P2X3 (B and D) receptors respectively. In both cases DRG neurons labelled with AuNPs functionalized with secondary antibodies become stably photosensitive. Reprinted from [23], copyright 2015, with permission from Elsevier.
