Abstract
Microstructures immersed in a liquid have multiple chambers and funnels oriented inwardly. The funnels generate differential motility for bacteria. Bacteria is therefore concentrated within the chamber, and effectively sequestered from the environment outside the microstructures. Multiple consecutive chambers and conical funnels allow more effective sequestration of bacteria. These microtraps offer biocontrol options alternative to pharmaceutical solution such as antibiotics.
Claims12
