چکیده
A simple biomimetic mercury(II)-gated single nanochannel has been developed by incorporating a mercury(II) responsive single stranded DNA (ssDNA) with thymine-thymine (T-T) bases into a single polymetic nanochannel.

pH gated glucose responsive biomimetic single nanochannels.
The development of pH gated glucose (Glu) biosensor is of great significance to human health. Herein, we have designed a pH gated Glu responsive biomimetic nanochannel, modified with 3-aminobenzeneboronic acid. The Glu responsive property can be regulated by pH which can switch nanochannels from the "on" to "off" state.
متن کاملMimicking the binding and unbinding of Fe3+ with transferrin using a single biomimetic nanochannel.
A new type of apo-Tf functionalized nanochannel is developed to achieve the specific and selective binding and unbinding of Fe(3+) in a multiple and reversible manner via a protein-conformation-gating mechanism. This ion-responsive biomimetic nanochannel provides a simple, robust, and promising model for studying other biological processes.
متن کاملChiral recognition of L-tryptophan with beta-cyclodextrin-modified biomimetic single nanochannel.
A stable system of enantioselectively recognising L-tryptophan based on β-cyclodextrin-modified single nanochannel fabricated in a polyimide membrane was demonstrated, and we realized the chiral recognition of an essential amino acid with this system for the first time.
متن کاملSimulation of single-molecule trapping in a nanochannel.
The detection and trapping of single fluorescent molecules in solution within a nanochannel is studied using numerical simulations. As optical forces are insufficient for trapping molecules much smaller than the optical wavelength, a means for sensing a molecule's position along the nanochannel and adjusting electrokinetic motion to compensate diffusion is assessed. Fluorescence excitation is p...
متن کاملSynthesis and crystal structure of mercury (II) complex Hg (Meca2en) I2
The mercury (II) complex, Hg (Meca2en)I2 (1), containing bidentate Schiff base ligand Meca2en = N,N′-bis[(E)-2-benzylidenepropylidene]ethane-1,2-diamine, has been synthesized and characterized by elemental analyses (CHN) and 1H-NMR spectroscopy. The crystal structure of 1 was determined using single-crystal X-ray diffraction. Structural investigation shows that 1 crystallizes in a monoclinic s...
