Sizing Channels with Neutral Polymers,of the availability of a wide range of size-selected nonelectrolyte polymers of poly(ethylene glycol), PEG, and because PEG decreases the bulk conductivity of ionic solutions. The method is simple. PEGs that are sufficiently small enter the channel’s pore and decrease the channel’s ionic conductanceFocus-Words 发表于 2025-3-25 08:21:28
Dynamic Partitioning of Neutral Polymers into a Single Ion Channel,nce of a channel depends on the state of occupancy of the pore by polymer and serves as a measure of polymer partitioning. Specifically, the movement of neutral polymer into the pore causes a reduction of the channel’s conductance. The mean conductance is used to determine the polymer partition coef蔓藤图饰 发表于 2025-3-25 13:54:08
Branched Polymers inside Nanoscale Pores,s sucked in by a solvent flux . higher than a threshold value ... For linear polymers . (where. is the temperature and η the solvent viscosity). We discuss here the case of statistically branched polymers, with an average number . of monomers between branch points. We find that, depending on the tub毕业典礼 发表于 2025-3-25 17:01:54
Physics of DNA Threading through a Nanometer Pore and Applications to Simultaneous Multianalyte Senion. To better understand the mechanisms of macromolecular transport, we are studying the ability of polymers to partition into and thread through single protein ion channels. It was recently shown in our laboratory that individual molecules of single-stranded DNA and RNA can be detected and charact歌曲 发表于 2025-3-25 23:08:07
