Abstract
Water-dispersible amphiphilic surface-engineered quantum dots (QDs) were found to be strongly accumulated within discrete zones of the exopolymer network of Shewanella oneidensis MR-1 biofilms, but not on the cell surfaces. These microdomains showed a patterned distribution in the exopolymer matrix, which led to a restricted diffusion of the amphiphilic nanoparticles.
摘要
水散性两亲表面工程量子点（QD）被发现强烈积聚在希瓦氏菌属 MR-1 生物膜的胞外聚合物网络的离散区域内，但不在细胞表面上。这些微区在胞外聚合物基质中呈现出图案分布，导致两亲性纳米粒子的扩散受到限制。
