We describe synthetic membranes in which the molecular recognition chemistry used to accomplish selective permeation is DNA hybridization. These membranes contain template-synthesized gold nanotubes with inside diameters of 12 nanometers, and a “transporter” DNA-hairpin molecule is attached to the inside walls of these nanotubes. These DNA-functionalized nanotube membranes selectively recognize and transport the DNA strand that is complementary to the transporter strand, relative to DNA strands…

DNA translocation in inorganic nanotubes.
TLDR
Inorganic nanotubes were successfully integrated with microfluidic systems to create nanofluidic devices for single DNA molecule sensing and a transition from current decrease to current enhancement during translocation was observed on changing the buffer concentration, suggesting interplay between electrostatic charge and geometric blockage effects.
Selective Detection of Single-Stranded DNA Molecules Using a Glass Nanocapillary Functionalized with DNA.
TLDR
It is demonstrated that single-base mismatch transport selectivity can be achieved using the DNA-functionalized nanocapillaries and that the event duration time is dependent on the base pair binding strength.
Towards sequence selective DNA binding: design, synthesis and DNA binding studies of novel bis-porphyrin peptidic nanostructures.
TLDR
Using UV-visible spectroscopy and induced circular dichroism, it is demonstrated that the compounds are fully intercalated upon binding to double-stranded DNA and that they exhibit a tremendous preference for GC over AT sequences for intercalation.
Gold Nanotube Membranes
In this review, we discuss gold nanotube membranes, which are of interest in the field of membrane separations. The review briefly describes the template synthesis approach based on electroless gold…
Solid State Nanopores for Selective Sensing of DNA
This chapter focuses on the functionalized solid state nanopores for the purpose of rapidly and accurately sensing specific sequence of DNA. Fabrication processes are described, consisting of…
Solid-state nanopore channels with DNA selectivity.
TLDR
Solid-state nanopore channels that are selective towards single-stranded DNA (ssDNA) are reported, providing a tool to gain fundamental insight into the channel-molecule interactions and the conceptual framework of diffusive molecular transport with particle-channel interactions.
Molecular discrimination inside polymer nanotubules.
TLDR
It is demonstrated here that proteins can be differentially transported through the nanopores based on their size and/or electrostatics, and it is shown that these modified membranes separate small molecules based on size, charge and hydrophobicity.
Gating Protein Transport in Solid State Nanopores by Single Molecule Recognition
TLDR
This work shows how nanopores functionalized with poly(ethylene glycol) brushes, which fully prevent protein translocation, can be reversibly gated to an “open” state by binding of single IgG antibodies that disrupt the macromolecular barrier.
DNA at aqueous/solid interfaces: chirality-based detection via second harmonic generation activity.
We present electronic spectra of single-strand and duplex DNA oligonucleotides covalently attached to fused quartz/aqueous interfaces and demonstrate that a strong nonlinear optical linear dichroism…
Regulating DNA translocation through functionalized soft nanopores.
TLDR
The proposed soft nanopore is capable of enhancing the performance of DNA translocation while maintaining its basic signature of the ionic current at high salt concentration and provides the necessary information for designing devices used in DNA sequencing.

Antibody-Based Bio-Nanotube Membranes for Enantiomeric Drug Separations
TLDR
Synthetic bio-nanotube membranes were developed and used to separate two enantiomers of a chiral drug, and an antibody that selectively binds one of the enantiomeric selectivity coefficient increases as the inside diameter of the silica nanotubes decreases.
Single-mismatch detection using gold-quenched fluorescent oligonucleotides

It is shown that this composite molecule is a different type of molecular beacon with a sensitivity enhanced up to 100-fold and the ability to detect single mismatch is eightfold greater with this probe than with other molecular beacons.

Thermodynamic basis of the enhanced specificity of structured DNA probes.
TLDR
The results show that molecular beacons can exist in three different states: bound to a target, free in the form of a hairpin structure, and free in a random coil, and thermodynamic analysis of the transitions between these states reveals that enhanced specificity is a general feature of conformationally constrained probes.
