Here we compare MUC1 and the well studied cell surface receptor target, EGFR, as gold nanoparticle (AuNP) targets and their subsequent vapor nanobubble generation efficacy in the human epithelial cell line, HES. Although EGFR and MUC1 were both highly expressed in these cells, TEM and confocal images revealed MUC1 as a superior target for nanoparticle intracellular accumulation and clustering. The MUC1-targeted AuNP intracellular clusters also generated significantly larger vapor nanobubbles. Our results demonstrate the promising opportunities MUC1 offers to improve the efficacy of targeted nanoparticle based approaches.engThis is an open access article distributed under the terms of the Creative Commons Attribution (CC BY-NC) License.The MUC1 Ectodomain: A Novel and Efficient Target for Gold Nanoparticle Clustering and Vapor Nanobubble GenerationJournal articleMUC1EGFRtargeted gold nanoparticlevapor nanobubblenanoparticle endocytosisnanoparticle clusteringhttp://dx.doi.org/10.7150/thno.4494
