ABSTRACT

Diatoms are microscopic algae found in almost all aquatic environments. Diatoms can grow 3D nano-and microstructures of 200–50 microns with structural features down to 10nm. For the orientation and immobilization of the diatoms into patterned arrays, a technique has been designed and evaluated based using light and nutrients as attractants. As a result, a 2D array of diatom silica shells was obtained which could be useful for manufacturing of complex micro /nano-structures. We used a pattern having 20 µm size spots separated by a distance of 200 µm to observe the directed motility of diatoms regulated by light or nutrients.
