Cartoon of the setup of the imaging SPR experiment. The inset shows the cyprids of Semibalanus balanoides and the arrows indicate their antennules. When the antennules get in contact with the surface, a bright spot appears in the SPR image. On “sticky” surfaces, adhesive material and thus the bright spot in SPR will remain as a footprint in the image. The magnified view of the contact point illustrates schematically the probing depth of SPR of a few hundreds of nanometers (reproduced from Ref.[107] (Fig. 1, ^©Springer 2009) with kind permission from Springer Science and Business Media)
