Conductive but low-cost materials, such as copper, can be coated with functional yet higher-cost materials such as gold or silver using electrodeposition to lower the overall cost while maintaining functionality. When the electrodeposition of multiple materials is required, current methods use a multistep process that deposits one material at a time, which requires a significant amount of time and a significant number of steps. Additionally, they use a large volume of electrolytes suitable for coating large objects, which is wasteful and unnecessary for the prototyping or coating of microelectrodes with a small area. In this paper, a new method of electroplating is introduced in which we used gels to immobilize and pattern electroplating electrolytes on a substrate surface. Agarose, as an immobilizing medium, enables the immersion of the substrate in a common working electrolyte without cross-mixing different electrolytes. We demonstrate the printing of jelly electrolytes by using spot-dispensing or microfluidic flow. Xurographically patterned films laminated on the substrate function as a mask and confine the printed gels to desired locations. After printing, the substrate is placed in a common working electrolyte container, and multimaterial patterns are produced through the application of an electrical current in a single step.<\/jats:p>","DOI":"10.3390\/s20030886","type":"journal-article","created":{"date-parts":[[2020,2,7]],"date-time":"2020-02-07T11:50:28Z","timestamp":1581076228000},"page":"886","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Electroplating of Multiple Materials in Parallel Using Patterned Gels with Applications in Electrochemical Sensing"],"prefix":"10.3390","volume":"20","author":[{"given":"Aliakbar","family":"Mohammadzadeh","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, McMaster University, Hamilton, ON L8S 4L7, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alison","family":"Fox-Robichaud","sequence":"additional","affiliation":[{"name":"Department of Medicine, McMaster University, Hamilton, ON L8L 2X2, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2041-7180","authenticated-orcid":false,"given":"P.
