DNA-centered approaches to characterize regulatory protein–DNA interaction complexes

Gene regulation is mediated by site-specific DNA-binding proteins or transcription factors (TFs), which form protein complexes at regulatory loci either to activate or repress the expression of a target gene. The study of the dynamic properties of these re ...

Interdigitated electrode DNA biosensor for detection of food-borne pathogens by impedance spectroscopy

Daniel Berdat

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. ...

New insights for using self-assembly materials to improve the detection stability in label-free DNA-chip and immuno-sensors

Sandro Carrara, Luca Benini, Andrea Cavallini, Anna Ferretti, Bruno Samori

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 curse of taxonomic uncertainty in biogeographical studies of free-living terrestrial protists: a case study of testate amoebae from Amsterdam Island

Edward Mitchell, Thierry Jean Heger

Aim A current debate in microbial biogeography contrasts two views concerning the distribution of free-living microorganisms. The first view assumes a ubiquitous distribution, while the second view assumes that at least some species have limited geographic ...

A fully electronic label-free DNA sensor chip

Sandro Carrara, Carlotta Guiducci

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 ...

Interface Layering Phenomena in Capacitance Detection of DNA with Biochips

Giovanni De Micheli, Sandro Carrara, Carlotta Guiducci, Yusuf Leblebici, Luca Benini, Bruno Samori

Reliable DNA detection is of great importance for the development of the Lab-on-chip technology. The effort of the most recent projects on this field is to integrate all necessary operations, such as sample preparation (mixing, PCR amplification) together ...

Vertebrate conserved non coding DNA regions have a high persistence length and a short persistence time

Philipp Bucher

ABSTRACT: BACKGROUND: The comparison of complete genomes has revealed surprisingly large numbers of conserved non-protein-coding (CNC) DNA regions. However, the biological function of CNC remains elusive. CNC differ in two aspects from conserved protein-co ...

Community and cultivation analysis of arsenite oxidizing biofilms at Hot Creek

Janet Gordon Hering

At Hot Creek in California, geothermally derived arsenite is rapidly oxidized to arsenate. This process is mediated by microorganisms colonizing the surfaces of submerged aquatic macrophytes in the creek. Here we describe a multifaceted approach to charact ...
