Journal ArticleDOI
Controlling protein translocation through nanopores with bio-inspired fluid walls
Erik Yusko,Jay M. Johnson,Sheereen Majd,Panchika Prangkio,Ryan Rollings,Jiali Li,Jerry Yang,Michael Mayer +7 more
TL;DR: It is shown that coating nanopores with fluid bilayer lipids allows the pore diameters to be fine-tuned in sub-nanometre increments, and incorporation of mobile ligands in the lipid conferred specificity and slowed down the translocation of targeted proteins sufficiently to time-resolve translocation events of individual proteins.
Journal ArticleDOI
Ion selectivity of graphene nanopores
TL;DR: It is shown that single graphene nanopores preferentially permit the passage of K+ cations over Cl− anions with selectivity ratios of over 100 and conduct monovalent cations up to 5 times more rapidly than divalent cations.
Journal ArticleDOI
Real-time shape approximation and fingerprinting of single proteins using a nanopore.
Erik Yusko,Brandon R. Bruhn,Olivia M. Eggenberger,Olivia M. Eggenberger,Jared Houghtaling,Jared Houghtaling,Ryan Rollings,Nathan Walsh,Santoshi Nandivada,Mariya A. Pindrus,Adam R. Hall,David Sept,Jiali Li,Devendra S. Kalonia,Michael Mayer,Michael Mayer +15 more
TL;DR: The zeptolitre sensing volume of bilayer-coated solid-state nanopores can be used to determine the approximate shape, volume, charge, rotational diffusion coefficient and dipole moment of individual proteins.
Journal ArticleDOI
Single-particle characterization of Aβ oligomers in solution.
TL;DR: The potential of resistive-pulse sensing through lipid bilayer-coated nanopores to measure the size of individual amyloid-β oligomers directly in solution and without chemical modification is explored.
Journal ArticleDOI
Threading immobilized DNA molecules through a solid-state nanopore at >100 μs per base rate.
TL;DR: An apparatus that can place a DNA-tethered probe tip near a solid-state nanopore, control the DNA moving speed, and measure the ionic current change when a DNA molecule is captured and released from a nanopore is designed and constructed.
