Electrical manipulation of oligonucleotides grafted to charged surfaces.
The electrical manipulation of short DNA molecules on surfaces offers novel functionalities with fascinating possibilities in the field of bio-interfaces. Here we present systematic investigations of the electrical interactions which govern the structure of oligonucleotides on charged gold surfaces. Successively, we address influences of the applied field strength, the role of DC electrode pote...
متن کاملElectric field manipulation of charged copolymer worm micelles.
Manipulation of diblock copolymer worm micelles by external electric fields is visualized by fluorescence microscopy in dilute, aqueous solution. Hydrodynamic coupling of the poly(acrylic acid)-(1,4)-polybutadiene (PAA-PBD) worm motion to the electric field and the effective stiffening of the worms in an oscillating electric field are demonstrated. A brief discussion on using this technique to ...
متن کاملManipulation Planning with Probabilistic Roadmaps Manipulation Planning with Probabilistic Roadmaps
This paper deals with motion planning for robots manipulating movable objects among obstacles. We propose a general manipulation planning approach capable of addressing continuous sets for modeling both the possible grasps and the stable placements of the movable object, rather than discrete sets generally assumed by the previous approaches. The proposed algorithm relies on a topological proper...
متن کاملManipulation of charged residues within the two‐peptide lantibiotic lacticin 3147
Lantibiotics are antimicrobial peptides which contain a high percentage of post-translationally modified residues. While most attention has been paid to the role of these critical structural features, evidence continues to emerge that charged amino acids also play a key role in these peptides. Here 16 'charge' mutants of the two-peptide lantibiotic lacticin 3147 [composed of Ltnα (2+, 2-) and L...
متن کاملElectric field isolator (EFI) for isolated and electrophoretic manipulation of charged biomolecules.
This paper describes a novel technology-an electric field isolator (EFI)-that can be used for achieving isolated and electrophoretic manipulation of charged biomolecules inside a selected microscopic location. The EFI is a ground ring-shaped electrode (RE) surrounding a centre electrode (CE), which is comprised of a functional unit. When the CE is powered, the ground RE can inhibit the electric...
