微細構造表面におけるフジツボ幼生の付着前行動

抄録

  Recently, antifouling activities of micro-structured surfaces against marine sessile organisms have been reported. However, antifouling mechanisms of micro-structured surfaces have remained unclear until now. During their pre-settlement stage, cypris larvae of barnacles, which are popular marine sessile organisms, explore substrates with their two sensory organs. It is considered that the exploring behavior is intended to determine the most suitable substrate for their settlement.

  In this study, we investigated pre-settlement larval behavior of barnacle on micro-structured surfaces. The results found no settled cypris on self-assembled honeycomb-structured porous films. Furthermore, most of non-settled cypris quitted their exploration on the honeycomb-structured surface at an early stage.
