1. Quantificação de forças na manipulação de nano-objetos individuais em experimentos "in situ" de mocroscopia eletronica / Quantification of forces on the manipulation of individual nano-objects in "in situ" experiments of electron microscopy
O estudo de nano-sistemas tem atraído grande atenção nos últimos anos, principalmente devido às suas possíveis e novas aplicações tecnológicas. Muitos esforços têm sido feitos nessa área, porém há ainda várias questões em aberto com relação à compreensão de nanoestruturas. Um dos principais desafios diz respeito à manipulação e o posic

2. Protein decorated Nanoparticules : Small Unilamellar Lipid Vesicules and Block Copolymers Micelles. / Nanoparticules Décorées par des Protéines : Vésicules Lipidiques Unilamellaires et Micelies à Base de Copolymères à Blocs
The formation of protein Annexin-A5 decorated (bio-functionalized) nanoparticles is of particular interest in micelle-mediated target drug delivery, in vivo magnetic resonance imaging, or controlled fabrication of biochips. This work describes an easy access to the synthesis and manipulation of block copolymer nano-objects exhibiting binding ability for the

3. Nanomanipulation and characterization of individual nano-objects for in situ experiments of electron microscopy / Nanomanipulação e caracterização de nano-objetos individuais por experimentos in situ de microscopia eletronica
It is expected that, in the future, high-technology devices should be based on new and unexpected physical and chemical properties of nanometric objects. Many applications require nano-objects to be selectively positioned at well-defined positions of a device. However, the well-established methods of physical manipulation used in the macroscopic scale are no

4. Magneto-optics of layers of semiconductor quantum dots and nano-rings
We have studied the collective magneto-optical response of layers of semiconductor quantum dots and nano-rings. Expressions for both the polarizability of the individual nano-objects have been used to determine the magneto-optical response on square two-dimensional lattices on those nano-objects as a function on frequency, magnetic field and angle of inciden

5. TectoRNA: modular assembly units for the construction of RNA nano-objects
Structural information on complex biological RNA molecules can be exploited to design tectoRNAs or artificial modular RNA units that can self-assemble through tertiary interactions thereby forming nanoscale RNA objects. The selective interactions of hairpin tetraloops with their receptors can be used to mediate tectoRNA assembly. Here we report on the m
