A molecular motor “lawnmower” made from trypsin enzymes attached to a polystyrene-
based bead moves in a directed manner by breaking chemical bonds in a lawn of peptides …

Molecular motors of the cell are protein-based, nanoscale machines, which use a variety of
strategies to transduce chemical energy into mechanical work in the presence of a large …

Inspired by biology, great progress has been made in creating artificial molecular motors.
However, the dream of harnessing proteins-the building blocks selected by Nature-to design …

Molecular motors are protein-based machines essential for directional transport of cellular
components. Inspired by biology, we have synthesized and characterized a protein-based …

This work is related to efforts by several teams of bioengineers to envision molecular motor–
based technology and build proof-ofprinciple devices that radically depart from current …

Machines and motors based on synthetic small molecules are realized by a “bottom-up”
approach to nanotechnology (1–3) and could exploit molecular motion in one of two ways …

Motor proteins and other biological machines are highly efficient at converting energy into
directed motion and driving chemical systems away from thermodynamic equilibrium. But …

Biomolecular motors are often described in mechanical terms, with analogy to cars, turbines,
judo throws, levers, etc. It is important to remember however that because of their small size …

We use machines to move, to lift, and to build. In a similar way, cells use machines to grow,
to reproduce, and to live. These machines play essential roles in cellular functions such as …
