Here, the spatially defined photodeposition of gold nanoparticles onto periodically proton exchanged lithium niobate is demonstrated. It is shown that the location where the gold nanoparticles form can be tailored by altering the concentration of HAuCl4. This enables the possibility to sequentially deposit gold and silver in different locations to create bimetallic arrays. The cytocompatibility of photodeposited gold, silver, and bimetallic ferroelectric templates to osteoblast-like cells is also investigated. Gold samples provide significantly greater cell biocompatibility than silver samples. These results highlight a potential route for using photodeposited gold on lithium niobate as a template for applications in cellular biosensing.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||ACS||Journal:||ACS Biomaterials Science and Engineering||Volume:||2||Issue:||8||Start page:||1351||End page:||1356||Copyright (published version):||2016 American Chemical Society||Keywords:||Ferroelectric; Atomic force microscopy; Photochemistry; Metallic nanoparticles; Metallic nanostructures; Biocompatibility; Patterning||DOI:||10.1021/acsbiomaterials.6b00264||Language:||en||Status of Item:||Peer reviewed|
