Micro/nanomotors (MNMs) are miniaturized machines that can convert many kinds of energy
into mechanical motion. Over the past decades, a variety of driving mechanisms have been …

Conspectus Enzymes are ubiquitous in living systems. Apart from traditional motor proteins,
the function of enzymes was assumed to be confined to the promotion of biochemical …

Motility in living systems is due to an array of complex molecular nanomotors that are
essential for the function and survival of cells. These protein nanomotors operate not only …

Using fluorescence correlation spectroscopy, we show that the diffusive movements of
catalase enzyme molecules increase in the presence of the substrate, hydrogen peroxide, in …

Recent studies have shown that the diffusivity of enzymes increases in a substrate-
dependent manner during catalysis,. Although this observation has been reported and …

Synthetic nano-and microscale machines move autonomously in solution or drive fluid flows
by converting sources of energy into mechanical work. Their sizes are comparable to …

The concept of a “power stroke”—a free‐energy releasing conformational change—appears
in almost every textbook that deals with the molecular details of muscle, the flagellar rotor …

Nature has designed multifaceted cellular structures to support life. Cells contain a vast
array of enzymes that collectively perform essential tasks by harnessing energy from …

Enzymes have been recently found to exhibit enhanced diffusion due to their catalytic
activities. A recent experiment [C. Riedel et al., Nature (London) 517, 227 (2015)] has found …

Recent experiments have revealed that the diffusivity of exothermic and fast enzymes is
enhanced when they are catalytically active, and different physical mechanisms have been …
