The photophysical properties of multichromophoric systems consisting of eight red or blue naphthalene diimides (NDIs) covalently attached to a p-octiphenyl scaffold, as well as a blue bichromophoric system with a biphenyl scaffold, have been investigated i ...
Electrophorescing blopolymers across nanopores modulates the ionic current through the pore, revealing the polymer's diameter, length, and conformation. The rapidity of polymer translocation (similar to 30 000 bp/ms) in this geometry greatly limits the inf ...
The central goal of this thesis work is to fabricate novel, functional fluorescent nanostructures in confined systems offered by phospholipid membranes, which are known to have highly ordered, thermotropic and lyotropic structures. In separate approaches, ...
The authors describe a strategy for the synthesis of 'nanocrystal mols.', in which discrete nos. of Au nanocrystals are organized into spatially defined structures based on Watson-Crick base-pairing interactions. The authors attach single-stranded DNA olig ...
Here we present a novel printing technique (that we call supramolecular nanostamping), based on the replication of single-stranded DNA features through a hybridization-contact-dehybridization cycle. On a surface containing features each made of single-stra ...
A new concept based on microstructuring techniques is presented to achieve size-dependent electrophoretic migration of DNA in free solution. Topographically structured microfluidic channels with periodical cavities in the range of the radius of gyration of ...
The outer membrane protein OmpF from Escherichia coli is a member of a large family of b-barrel membrane proteins. Some, like OmpF, are pore-forming proteins while others are active transporters or enzymes. We have previously shown that the receptor-bindin ...
The self-assembly in aqueous solution of hybrid block copolymers consisting of amphiphilic ?-strand peptide sequences flanked by one or two PEG chains was investigated by means of circular dichroism spectroscopy, small-angle X-ray scattering, and transmiss ...
In a recent paper, a new class of synthetic lipids, which self-assemble to form monolayers on gold surfaces, was introduced. The addn. of a monolayer of phospholipids to these layers results in robust supported lipid bilayers designed to reconstitute trans ...
A lipopeptide, carrying the antigenic peptide segment 135-154 of VP1, one of the capsid proteins of the picornavirus which causes foot-and-mouth disease in cattle, was investigated in lipid monolayers on the water surface and on hydrophobic solid supports. ...
