We propose a novel characterization method of randomly branched polymers based on the geometrical property of such objects in confined spaces. The central idea is that randomly branched polymers exhibit a passing/clogging transition across the nanochannel as a function of the channel size. This critical channel size depends on the degree of the branching, whereby allowing the extraction of the branching information of the molecule.
我们基于受限空间中此类物体的几何特性，提出了一种新型的随机支化聚合物表征方法。其核心思想是，随机支化聚合物会随着纳米通道尺寸的变化，在纳米通道中呈现通过/堵塞转变。这个临界通道尺寸取决于支化程度，从而能够提取分子的支化信息。
