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.

Fabrication and Functionalization of Inorganic Materials Using Amphiphilic Molecules

“…The rest of the functionalized template surface was covered with trifluoromethyl groups and was negatively charged. Electrostatic attractive forces between the silica particles and the amino groups resulted in the formation of self-assembled arrays of silica particles only in the region covered with amino groups 64 .…”

Fabrication and BSA Adsorption/Desorption Properties of Titania/Silica Composite Films Modified with Silane Coupling Agents

“…We have succeeded in fabricating self-assembled arrays of silica particles modified with bovine serum albumin BSA on oxidized Si wafers modified with silane coupling agents having amino groups 31,32 . The electrostatic interaction between the carboxylic groups of BSA adsorbed onto silica particles and the amino groups on the Si wafers led to the arrangement of silica particles.…”

Patterning of Solution-Processable Materials on Templates Fabricated from Mixed Langmuir-Blodgett Films

“…The surface of the ex-domain region is hydrophilic while the remainder is hydrophobic. Using this method, we have obtained patterned Cu films 53 , zirconia 54 , gold nanoparticles 55 , silica nanoparticles 56,57 , J-aggregated dyes 58 , and semiconductor quantum dots 59 on templates.…”
