The hallowed scene / Which others rave on, though they know it not.

PT Au NRs with average length of 210 ± 10 nm and width of 34 ± 1 nm were prepared as previously described by Pérez-Juste et al., with minor modifications (see Experimental Section). 49 The purified PT Au NRs show a shape yield around 99%, (Figure S1A–C, Supporting Information ) and can be used as seeds after redispersion in 10 mM benzyldimethylhexadecylammonium chloride (BDAC).

The control problem in these systems is challenging, especially with gravity coupling and large deformations, because of inherent underactuation and the combination of lumped and distributed parameters of a nonlinear system.
