Abstract
Disclosed is a method of manufacturing colloidal crystals using a confined convective assembly, more particularly, to a method for manufacturing two-dimensional and/or three dimensional colloidal crystals on a substrate by infusing colloidal suspension between two substrates and self-assembling colloidal particles by capillary action. The present invention can control a convective flow moving the colloidal particles to a meniscus generated by removing the solvent of the colloidal suspension. It is possible to manufacture face-to-face two-dimensional colloidal crystals and/or three-dimensional colloidal crystals within a short time using various sizes of colloidal particles through the control of the convective flow of colloidal particles, which are not easily achieved in the existing method. The present invention can use two-dimensional colloidal crystals and/or three-dimensional colloidal crystals manufactured using the confined convective assembly method in the various fields such as in biosensors and devices, information storing medium, display devices and optical devices.
