Electrochemical nucleic acid biosensors for the detection of interaction between peroxynitrite and DNA
(WILEY-V C H VERLAG GMBH, 2007-07)
We studied the reactivity of peroxynitrite and different nucleic acid molecules using DNA electrochemical biosensors. SIN-1 (3-morpholinosydnonimine) has been used for the simultaneous generation of NO- and superoxide, ...
Medida da elasticidade entrópica de uma molécula de DNA
(Universidade Federal de Minas GeraisUFMG, 2001-03-13)
In this work we combine optical tweezer and videomicroscopy techniques to obtain the entropic elastic behavior of single ¸ phage DNA molecules. By tethering a single DNA molecule by one end to a 3¹m poliestirene bead and ...

Dissociation of Rad51 Presynaptic Complexes and Heteroduplex DNA Joints by Tandem Assemblies of Srs2
(Elsevier, 2017-12)
Srs2 is a superfamily 1 (SF1) helicase and antirecombinase that is required for genome integrity. However, the mechanisms that regulate Srs2 remain poorly understood. Here, we visualize Srs2 as it acts upon single-stranded ...
Pinças ópticas: experimento, teoria e aplicação no estudo da interação DNA-fármacos
(Universidade Federal de Minas GeraisUFMG, 2008-03-19)
We started this work studying the physics of optical tweezers. This isa micromanipulation technique much used to study particles and biological systems with size in the micrometer range. We theoretically analyze the ...
Toxic and genotoxic effects of trivalent and hexavalent chromium - A review
(2005-06-01)
During the last years, the emission of heavy metals to the environment has increased, causing a severe negative impact to the ecosystems and seriously compromising human health due to their mutagenic potential. Tri- (III) ...
Carboplatin as an alternative to Cisplatin in chemotherapies: New insights at single molecule level
(Biophysical Chemistry, 2018)
A Model Coupling Vibrational and Rotational Motion for the DNA Molecule
(Springer, 2008-01-01)
We investigate a mechanical model for the DNA molecule using an extension of the Peyrard and Bishop model. In the present model, there are two chains of oscillators linked by a Morse potential, which represent the hydrogen ...
