Directing Single-Molecule Emission with DNA Origami-Assembled Optical Antennas
(American Chemical Society, 2019-08)
We demonstrate the capability of DNA selfassembledoptical antennas to direct the emission of anindividual fluorophore, which is free to rotate. DNA origami isused to fabricate optical antennas composed of two colloidalgold ...
Medida da força entrópica de uma molécula de DNA
(Universidade Federal de Minas GeraisUFMG, 2001-09-04)
This work combines optical tweezer, videomicroscopy and photon correlation techniques in order to study the entropic elastic behaviour of single A-fage DNA molecules. A DNA molecule is attached by one end to the surface ...
Simulating DNA chip design using all-electronic graphene-based substrates
(2019-01-01)
In this paper, we present a theoretical investigation of an all-electronic biochip based on graphene to detect DNA including a full dynamical treatment for the environment. Our proposed device design is based on the changes ...
Cooperative RNA Polymerase Molecules Behavior on a Stochastic Sequence-Dependent Model for Transcription Elongation
(2013-02-21)
The transcription process is crucial to life and the enzyme RNA polymerase (RNAP) is the major component of the transcription machinery. The development of single-molecule techniques, such as magnetic and optical tweezers, ...
Electron migration in DNA matrix: an electron transfer reaction
(Editora Unesp, 1998-01-01)
Este artigo apresenta uma área de pesquisa atual, ativa e interessante. Descreve a investigação da química de transferência de elétrons (TE) de um modo geral e resultados de TE em DNA em particular. Dois intercalantes de ...

Controlling cooperativity in β-cyclodextrin–DNA binding reactions
(The Journal of Physical Chemistry Letters, 2018)
Desenvolvimento de uma representação mesoscópica para marcadores fluorescentes em DNA e predição de intensidade de fluorescência
(Universidade Federal de Minas GeraisBrasilICB - INSTITUTO DE CIÊNCIAS BIOLOGICASPrograma de Pós-Graduação em BioinformaticaUFMG, 2020-02-18)
Fluorescent dyes attached to DNA molecules are used in biomedicine and biotechnology areas, for example, and they can be studied with mesoscopic models such as Peyrard-Bishop model (PB). In particular, Cy3 and Cy5 dyes ...
Estudo da interação DNA-ciclodextrina com a técnica de pinçamento óptico com aplicação em terapia gênica
(Universidade Federal de Minas GeraisUFMG, 2009-03-03)
In one of the methods of gene therapy, DNA of normal cells are encapsulated inside liposomes (lipids vesicles) which are transferred by endocytosis into the unhealthy cells. However, the amount of pure DNA that may be ...
