Journal ArticleDOI
Complex micromachines produced and driven by light
Peter Galajda,Pál Ormos +1 more
TL;DR: In this article, a method is introduced to build microscopic light driven rotors that are created and manipulated in laser tweezers, which can be used to build complex mechanical machines of micrometer size.
Journal ArticleDOI
A Wall of Funnels Concentrates Swimming Bacteria
TL;DR: The funnel effect is shown, which shows that when a population of bacteria is exposed to a microfabricated wall of funnel-shaped openings, the random motion of bacteria through the openings is rectified by tracking (trapping) of the swimming bacteria along the funnel wall.
Journal ArticleDOI
Bacterial growth and motility in sub-micron constrictions
TL;DR: The results reveal that sub-micron size pores and cavities are unexpectedly prolific bacterial habitats where bacteria exhibit morphological adaptations.
Journal ArticleDOI
Bacterial metapopulations in nanofabricated landscapes
TL;DR: By patterning habitat differences across the landscape, this device physically implements an adaptive landscape and observes rapid adaptation to large-scale, low-quality (high-stress) areas in landscapes with higher niche diversity.
Journal ArticleDOI
Hydrodynamic Trapping of Swimming Bacteria by Convex Walls.
TL;DR: The results demonstrate that the main mechanism for wall entrapment is hydrodynamic in nature and show the possibility of inhibiting cell adhesion, and thus biofilm formation, using convex features of appropriate curvature.
