“…Mallouk et al demonstrated the internalization of a nanowire-based motor inside living cells, as shown in Figure 25D. Developing biocompatible materials and fuels for artificial micro-/ nanomotors or the use of noninvasive external triggered motors may pave the way for biomedical applications of micro-/nanomotors in the near future [72][73][74][75][76][77][78][79][80].…”

Micro-/nanomotors are self-propelled micro-/nanomachines, which are capable of converting the surrounding fuels into mechanical movement or force. Inspired by naturally occurring biomolecular motor proteins, scientists extensively paid great attentions to synthetic micro-/nanomotors. Especially, a number of researchers devoted their efforts onto catalytic micro-/nanomotors. In the past few decades, several advanced developments and excellent contributions have been made in catalytic micro-/nanomotors. The future of this research field can be bright, but some major existing challenges such as biocompatible materials and fuels, smart controlling, and specifically practical applications are still required to be resolved. Therefore, it is essential for us to learn the state of the art of catalytic micro-/nanomotors. In this chapter, the propulsion mechanisms, fabrication methods, controlling strategies, and potential applications of catalytic micro-/nanomotors are presented and summarized.

In this article, a miniature micromotor comprising of gold, nickel, and platinum is proposed. Herein, platinum acting as a chemical catalyst stimulates hydrogen peroxide to decompose into water and oxygen bubbles separated from the surface, which conversely produces a recoil force to drive the gold-nickelplatinum micromotor propelling forward. The micromotor is synthesized by a layer-by-layer coating strategy based on the micro-electro-mechanical systems technology. The propulsion of the as-synthesized micromotor is experimentally conducted in diluted hydrogen peroxide both with and without the presence of external magnetic field, disclosing that oxygen bubbles are produced and separated from the platinum surface. Moreover, the results show that the speed of the gold-nickel-platinum micromotor is larger at higher hydrogen peroxide concentration, and the micromotor is able to move forward in an either linear or circular trajectory depending on the separation site of oxygen bubbles, the propulsion path of the micromotor can be manipulated by external magnetic field as well. Hence, the propulsion of the micromotor is chemical reaction-and magnetic field-dependent. In addition, the surfactant effect on the propulsion of micromotor and its application for E. coli transportation are investigated.

“…However, for gold nanohelices 400 nm high, 400 nm in diameter, and 80 nm thick nanowires, the chirality enhancement factor was determined as 10, so the use of such structures in biosensing is limited [75]. This problem was solved by fabricating superstructures with several nanohelices [76] using direct laser recording methods [77,78] or ion-and electron beam lithography [79][80][81]. The use of such structures made it possible to increase the optical chiral amplification factor up to two orders of magnitude and to adjust the CD signal from IR to the visible region of the spectrum.…”

“…The following review demonstrated the formation of chiral nanocrystals of Te and Se, which can be used as a matrix for growing nanostructures of gold and silver tellurides [87]. Also, there was presented the growth of chiral gold nanoparticles in the opposite direction induced by amino acids and peptides [77]. The effect of different growth rates on the chiral morphology of gold nanocrystals in the presence of L-Cys or D-Cys was observed.…”
