Abstract:
1. A method for producing a helical fine structure characterized by comprising the steps of: filter-washing a phytoplankton. using running water while holding the phytoplankton by a mesh filter having an opening size of 25 μm or smaller, wherein the phytoplankton has a helical shape, wherein the phytoplankton having a helical shape is a phytoplankton selected from the group of cyanobacteria called removing an outer membrane from a surface of the filter-washed phytoplankton by introducing the phytoplankton into an ethyl alcohol solution; passing the ethyl alcohol solution though a coarse mesh filter having an opening size of 250 μm or larger, wherein the ethyl alcohol solution contains the phytoplankton, floating pieces formed from assembled mucosa-like outer membrane lysates, and portions of a cytoplasm and a pigment component eluted into the ethyl alcohol solution, and thereby the floating pieces and the cytoplasm are trapped by the coarse mesh filter, while the ethyl alcohol solution containing the phytoplankton and the pigment is passed therethrough; passing the ethyl alcohol solution through a mesh filter having an opening size of 25 μm or smaller to trap the phytoplankton, wherein the ethyl alcohol solution contains the phytoplankton and the pigment and has passed through the coarse mesh filter; and forming a surface modification layer on the trapped phytoplankton, wherein the surface modification layer includes at least one metal plating layer.
