Selective molecular recognition of methylated lysines and arginines by cucurbit[6]uril and cucurbit[7]uril in aqueous solution.
Cucurbit[7]uril selectively binds the epigenetic mark N(ε),N(ε),N(ε)-trimethyllysine (LysMe(3), K(CB[7]) = (1.8 ± 0.6)× 10(6) dm(3) mol(-1)) by 3500-fold over lysine ((5.3 ± 0.7) × 10(2) dm(3) mol(-1)) in aqueous solution, using ion-dipole interactions and the hydrophobic effect, rather than cation-π interactions, as in the "aromatic cages" of p-SO(3)-calix[4]arene hosts or chromodomain protein...
متن کاملDynamic force spectroscopy of molecular adhesion bonds.
Recent advances in atomic force microscopy, biomembrane force probe experiments, and optical tweezers allow one to measure the response of single molecules to mechanical stress with high precision. Such experiments, due to limited spatial resolution, typically access only one single force value in a continuous force profile that characterizes the molecular response along a reaction coordinate. ...
متن کاملInterfacial propulsion by directional adhesion
The rough integument of water-walking arthropods is well known to be responsible for their water-repellency [1, 2, 3, 4]; however, water-repellent surfaces generally experience reduced traction at an air-water interface [5, 6, 7, 8]. A conundrum then arises as to how such creatures generate significant propulsive forces while retaining their water-repellency. We here demonstrate through a serie...
متن کاملMolecular Recognition and Adhesion of Individual DNA Strands Studied by Dynamic Force Microscopy
The development of versatile scanning probe methods such as atomic force microscopy (AFM) makes it today possible to study bio-adhesion on a single molecule level. In this paper, we present AFM-force-spectroscopy experiments on complementary DNA strands. From such experiments, intrinsic thermodynamical properties (energy landscape) of these weak non covalent bonds can be determined. Introductio...
متن کاملSupramolecular adhesives to hard surfaces: adhesion between host hydrogels and guest glass substrates through molecular recognition.
Supramolecular materials based on host-guest interactions should exhibit high selectivity and external stimuli-responsiveness. Among various stimuli, redox and photo stimuli are useful for its wide application. An external stimuli-responsive adhesive system between CD host-gels (CD gels) and guest molecules modified glass substrates (guest Sub) is focused. Here, the selective adhesion between h...
