Protein biosensing with track-etched single conical nanopores in polyimide
Currently, researchers are deeply involved in the field of nanopore technology due to its wide range of applications. Nanopores have been used for the detection and analysis of a variety of analytes, proteins, small organic molecules and metal ions [1-2]. So it becomes crucial to modify the chemistry of the nanopore walls to achieve desired interactions with molecules of interest. Single conica...
متن کاملNanopores with controlled profiles in track-etched membranes
The production of the track-etched membranes is well known in membrane science. Latent ion tracks are the result of the passage of swift ions through solid matter, they can be etched selectively in many materials. As a result, conical, cylindrical or other shape channels can be obtained. The increasing interest in polymer track-etched membranes with nano-channels is connected with the developme...
متن کاملSpace Charge Behavior in Low-Density Polyethylene
The space charge distribution in low-density polyethylene (LDPE) was measured with the pulsed electroacoustic (PEA) method. We used three types of LDPE: LDPE-L and LDPE-H were prepared by the high pressure process, and m-LDPE was polymerized with a metallocene catalyst. Space charge in LDPE strongly depended upon the electrode material. Semiconductive electrodes enhanced carrier injection into ...
متن کاملSeparation of Organic Molecules through Track-Etched Nanopores in PET Membranes
Chemical separations play an important role in most chemical, pharmaceutical, and petrochemical processes. Membrane-based separations are potentially important because they can be less energy intensive and more economical than conventional separation methods [1]. By controlling the pore diameter of track-etched nanoporous polymer membranes, they can be used as nanofilters for the separation of ...
متن کاملChemical Modification of track-etched dingle conical nanopores inducing inversed inner wall polarity
Nanopores are currently considered as promising candidates for a variety of applications, including separation techniques and biological sensing [1,2]. The pore surface properties are crucial for all these applications, since they influence the transport properties (e.g. hydrophobicity, selectivity) and chemical groups on the inner pore walls may serve as binding sites for analytes [3]. Therefo...
