Biochemical noise in single DNA molecule studied by optical trapping technique
(Universitat Politècnica de Catalunya, 2010-09-09)
Master thesis
Open AccessNoise spectra from single DNA molecules in their natural aqueous environment at different grades of stretching are presented. A DNA molecule is anchored between two dielectric beads. One of the beads is fixed to the surface ... -
Electrical charge of a single living cell measured by optical trap technique
(Universitat Politècnica de Catalunya, 2009-06-03)
Master thesis
Open AccessElectrical charge is an indicator of the cellular state of health. The exact local charge can be determined only by a non-invasive technique. This project aims at setting a method for the determination of the overall ... -
Emodin diffusion in cancerous living cells studied by means of Raman spectroscopy enhanced by plasmon effects
(Universitat Politècnica de Catalunya, 2009-06-09)
Master thesis
Open AccessEmodin (6-methyl-1,3,8 trihydroxyanthraquinone) is considered as a potential candidate for photodynamic therapy for the treatment of cancer. A success in using of the molecule depends among other factors on the knowledge ... -
Mechanochemical study of single living cells and biomolecules combining optical tweezers and raman spectroscopy
(Universitat Politècnica de Catalunya, 2012-11-05)
Doctoral thesis
Open AccessThis thesis is devoted to the study of mechanochemistry of single cells and single biomolecules. Mechanochemistry relates to the association of mechanical and chemical occurrence at the molecular level. Using a combination ... -
Noise assisted effects in physics and biophysics studied by the optical trapping technique
(Universitat Politècnica de Catalunya, 2014-04-25)
Doctoral thesis
Open AccessAlmost two centuries after the first observations of Robert Brown, the study of systems ruled by noise has become a significant part of modern physics and other so diverse situations, such as the stock market, personal ... -
Novel applications of Photonic Force Microscopy
(Universitat Politècnica de Catalunya, 2008-10-23)
Doctoral thesis
Open AccessThe ability of detecting farces and torques at the micro-and nano-scale is fundamental. When this Thesis started, various scanning probe techniques had already been developed to probe the mechanical properties of microsystems. ... -
Statistical analysis and plasmonic effects to extend the use of Raman spectroscopy in biochemistry
(Universitat Politècnica de Catalunya, 2013-07-12)
Doctoral thesis
Open AccessSince its discovery in 1928, Raman spectroscopy (RS) has produced a revolution in the fields of analytical chemistry and molecular detection. Thanks to the latest technical advances, the expectations of the applicability ... -
Using optical tweezers to measure electrophoretical mobility of yeast cells under different conditions
(Universitat Politècnica de Catalunya, 2012-07-17)
Master thesis
Open Access[ANGLÈS] Living cells contain different charged groups such as membranes, nucleus, histones, etc. The interaction of these groups with electric fields will afect the basic properties and behavior of cells by determining ...
