In the last decade, there has been a rapid development in the field of catalytically driven propulsion of colloidal particles and other devices that operate by converting chemical energy into translational motion in a viscous medium via a surface chemical reaction. It is becoming an area of important implications in a wide range of problems. These devices, whether individual, or assembled into desired architectures, might someday transport medicine in the human body, conduct operations in cells, move cargo around microfluidic chips or complex channels, manage light beams, agitate liquids close to surfaces, and search for and destroy toxic organic molecules in polluted water streams
A new paper has been accepted in Nano Letters on the dynamics of enzyme-coated spheres.
The research described in this paper will broadly advance our understanding of active matter in biological systems. Advances in our understanding of the biological responses in systems of active particle has the potential to enable new designs of smart fluids, fluid property sensors, and novel biomedical devices.
