Patterning of Silica Particles Using Self-Assembly on Two-Dimensional Patterns Fabricated from Phase-Separated Langmuir-Blodgett Films

Abstract

In this study, self-assembled arrays of silica particles were formed on the two-dimensional patterns of the functionalized templates fabricated from phase-separated mixed Langmuir-Blodgett films. Immersion of the functionalized templates into silica particle dispersion led to the formation of silica particle arrays due to the electrostatic interaction between the dissociated carboxylic groups originating from bovine serum albumin on the silica particles and the amino groups on the functionalized templates.
