Graphical table reporting the biosensing methods and the corresponding references considered in this review.
The references are placed in the graphic according to the type of sensing substrate and the type of target. References to works where a metallic (dielectric) substrate is used are reported on the left (right) half of the table. References to works adopting a nano- or micro-patterned (planar) sensing surface are reported on the lower (upper) half of the table. The position along the radial direction indicates the target type among bio-NPs, proteins, NAs, small molecules, and single molecules.
