Parallel or angle parked: Gold nanorods (see picture) were selectively modified either on the sides or ends using complementary microcystin (MC-LR) antibody and antigen (blue). Fast detection of MC-LR (green) was successfully achieved with these assemblies, and both sensitivity and detection ranges were markedly better for the end-to-end motif (right) than the side-to-side variant (left).
