We have determined limits of detection (LODs) of DNA hybridization using an optical detection by two different method, i.e., surface plasmon fluorescence spectroscopy (SPFS) and optical waveguide fluorescence spectroscopy (OWFS), however, an identical sens ...
In view of developing DNA biochips based on electric detection, well controlled DNA functionalisation of conductive substrate electrode is a challenging process. In this study, the whole process of functionalisation onto home made conductive films with con ...
We present and demonstrate a novel technique for the purification of nucleic acids from biological samples using isotachophoresis (ITP). We demonstrate a simple and rapid method to achieve ITP-based extraction, preconcentration, and purification of DNA fro ...
Two types of DNA biosensors are presented. Both sensing principles are demonstrated using synthetic oligomer single-stranded DNA (ssDNA) with concentrations in the micromolar range. A first sensor type is based on the detection of fluorescently labeled ssD ...
The invention relates to a method of preparing template constructs for solid-phase nucleic acid amplification and to use of the templates in methods of solid-phase nucleic acid amplification. The method involves carrying out two ligation reactions: (a) a l ...
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. ...
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 ...
First results are reported regarding the design, fabrication and operation of a DNA biochip based on a semiconductor oxide electrode that employs label-free electrical detection of the DNA hybridization. The same process of DNA functionalisation, including ...
• Goal The goal of the project was to produce biomolecular fingerprints in order to describe the structure of microbial community which develops during aerobic sludge granulation, initiated in sequencing batch wastewater treatment processes. Four SBR were ...
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 ...
