Are aluminium ions unavoidable in antiperspirants? To answer this question, we present confocal microscopy images of dendritic plugs appearing in sweat flowing across a microfluidic channel in the presence of aluminium salts. By comparing with numerical simulations, we identify the mechanisms forming this structured protein gel inside the pore.

生理条件下铝盐堵塞汗孔过程中蛋白质凝胶的树枝状生长

止汗剂中是否不可避免地含有铝离子？为了回答这个问题，我们展示了在铝盐存在的情况下流过微流体通道的汗液中出现的树枝状栓塞的共聚焦显微镜图像。通过与数值模拟的比较，我们确定了在孔内形成这种结构化蛋白质凝胶的机制。
