Abstract

Optical condensation is a method for the rapidly and densely assembling dispersoids on the substrate. Recently, we developed the metallic nanofilm-coated optical fiber (MNOF) module to perform optical condensation on the three-dimensionally arbitrary position in dispersion liquid although the convection profile was limited in the case of a two-dimensional photothermal source. In this work, we investigate the effect of interface on the optical condensation using MNOF by changing the position from the substrate. Remarkably, the assembly efficiency of optical condensation with MNOF can be 1 to 2 orders of magnitude higher than that of conventional optical condensation two-dimensional case. These results will lead to a high-performance analysis of various small objects, such as microbes and biomaterials.
