The commercial application of biosensors has had a significant impact in a number of areas, particularly in the field of medical diagnostics. But in spite of the great number of publications, only a few systems are commercially available in food analysis. ...
Genetically encoded fluorescent sensor proteins offer the possibility to probe the concentration of key metabolites in living cells. The approaches currently used to generate Such fluorescent sensor proteins lack. generality, as they require a protein that ...
This paper presents a microfabricated DNA chip for fully electronic, label-free DNA recognition, based on capacitance measurements. The chip has been fabricated in 0.5-mu m CMOS technology and it features an array of individually addressable sensing sites ...
This paper examines reliable advancements in low-cost DNA- and immuno-chips. Capacitance detection was successfully chosen to develop label-free bio-chips. Probe immobilization was rigorously investigated in order to obtain reliable capacitance measurement ...
The thesis presents the development of a custom made atomic force microscope (AFM) conceived to image biological molecules at low temperatures in ultrahigh vacuum conditions, and its application to DNA single molecule studies. Starting from a first prototy ...
The aim of this thesis was to explore the statistical physics and the mechanical properties of individual biomolecules, to study their interactions, and to develop new techniques based on atomic force microscopy (AFM). First, we exploit the high resolution ...
In this work we present the first results on a 'label-free' DNA analysis system based on hydrogenated amorphous silicon (a-Si:H) thin film sensors. The detection mechanism is based on absorbance measurements performed on DNA molecules in a buffer solution. ...
The conformation of NAD bound to dogfish lactate dehydrogenase (LDH) was reinvestigated by using an NMR expt. that allows one to exploit NOEs to det. internuclear distances between pairs of protons, without perturbation of spin-diffusion effects from other ...
A new concept based on microstructuring techniques is presented to achieve size-dependent electrophoretic migration of DNA in free solution. Topographically structured microfluidic channels with periodical cavities in the range of the radius of gyration of ...
We studied the structure of viral nucleoprotein complexes extracted from the nuclei of mouse cells infected with the immunosuppressive strain of the minute virus of mice (MVMi). Two types of complex were detected, with sedimentation coefficients of about 1 ...
