Abstract
The modern environmental and food analysis requires sensitive, accurate, and rapid methods. The growing field of biosensors represents an answer to this demand. Unfortunately, most biosensor systems have been tested only on distilled water or buffered solutions, although applications to real samples are increasingly appearing in recent years. In this context, biosensors for potential food applications continue to show advances in areas such as genetic modification of enzymes and microorganisms, improvement of recognition element immobilization, and sensor interfaces. This chapter investigates the progress in the development of biosensors for the rapid detection of food toxicants for online applications. Recent progress in nanotechnology has produced affordable, mass-produced devices, and to integrate these into components and systems (including portable ones) for mass market applications for food toxicants monitoring. Sensing includes chemical and microbiological food toxicants, such as toxins, insecticides, pesticides, herbicides, microorganisms, bacteria, viruses and other microorganisms, phenolic compounds, allergens, genetically modified foods, hormones, dioxins, etc. Therefore, the state of the art of recent advances and future targets in the development of biosensors for food monitoring is summarized as follows: biosensors for food analysis will be highly sensitive, selective, rapidly responding, real time, massively parallel, with no or minimum sample preparation, and platform suited to portable and handheld nanosensors for the rapid detection of food toxicants for online uses even by nonskilled personnel.

Abstract
It is beneficial to develop systems that reproduce complex reactions of biological systems while maintaining control over specific factors involved in such processes. We demonstrated a DNA device for following the repair of DNA damage produced by a redox-cycling anticancer drug, beta-lapachone (β-lap). These chips supported ß-lap-induced biological redox cycle and tracked subsequent DNA damage repair activity with redox-modified DNA monolayers on gold. We observed drug-specific changes in square wave voltammetry from these chips at therapeutic ß-lap concentrations of high statistical significance over drug-free control. We also demonstrated a high correlation of this change with the specific ß-lap-induced redox cycle using rational controls. The concentration dependence of ß-lap revealed significant signal changes at levels of high clinical significance as well as sensitivity to sub-lethal levels of ß-lap. Catalase, an enzyme decomposing peroxide, was found to suppress DNA damage at a NQO1/catalase ratio found in healthy cells, but was clearly overcome at a higher NQO1/catalase ratio consistent with cancer cells. We found that it was necessary to reproduce key features of the cellular environment to observe this activity. Thus, this chip-based platform enabled tracking of ß-lap-induced DNA damage repair when biological criteria were met, providing a unique synthetic platform for uncovering activity normally confined to inside cells.

Abstract
Absorption of UV light by nucleic acids can result in the formation of molecular lesions in DNA and RNA, leading to mutagenesis, carcinogenesis, and cell death. In this work, hairpin oligonucleotide probes, which have previously been shown to be selective for DNA damage, are used. The hypochromic effect, which arises from the formation of the target–hairpin hybrid when there is no damage, is used to measure the amount of UV damage by measuring the amount of single-stranded DNA oligonucleotides. With accumulated UV exposure, the target–hairpin hybrid concentration decreases and the absorbance increases, enabling detection of UV-induced DNA damage. Our results show that the selectivity for DNA damage of the hypochromism probe is comparable with the molecular beacon probes, detecting between one and three lesions in an oligonucleotide. In addition, this probe is more than 10 times cheaper than molecular beacon probes. However, it shows lower sensitivity to DNA damage. This makes its use recommended for high-throughput, qualitative analysis of DNA damage. This introduces a simple, fast, mix-and-read assay for the detection of DNA damage.

Abstract
First papers on electroactivity of DNA and RNA were published more then 50 years ago. For about 8 years oscillographic polarography at controlled a.c. (OP, proposed by J. Heyrovský already in 1941) was the method of choice for DNA analysis. Since approximately 1954 Robert Kalvoda developed OP for wide application in various fields. It is shown that already before 1960 it was possible to detect damage to DNA in X-ray-irradiated rats by means of OP. DNA samples from irradiated animals produced significantly larger OP anodic guanine signal indicating changes in the DNA structure. At present, radiation-induced strand breaks and damage to bases in DNA can be electrochemically detected at high sensitivity.

Abstract
The molecular level damage to DNA is important due to DNA's susceptibility to free radical attacks and crucial roles in maintaining cell functions. Although a panel of techniques can be used to detect DNA damages, most of them are limited due to low sensitivity, low throughput, incompatibility for automated data analysis, and labor-intensive operations. We have developed a cell array based DNA damage assay in which mammalian cells are attached on an array of microfabricated patterns through electrostatic interactions. After trapping patterned cells inside gels, damaged DNA fragment can diffuse out of the nucleus and form a halo around each cell inside gels. The halo array can be observed fluorescently after labeling DNA with ethidium bromide. DNA damages can be determined sensitively at the single cell level, accurately due to the symmetric shape of the halo, and automatically due to the spatial registry of each cell and the nonoverlapping halos surrounding cells. The HaloChip can be used to detect DNA damages caused by chemicals and ultraviolet and X-ray irradiations with high efficiency. A major advantage of HaloChip is the ability to increase throughout by spatially encoding multiple dosing conditions on the same chip. Most importantly, the method can be used to measure variations in response to DNA damaging agents within the same cell population. Compared with halo assay or comet assay alone, this method allows automated analysis of a million cells without an overlapping issue. Compared with the microwell array based comet assay, this method can selectively capture and analyze cells, and the results can be easily analyzed to provide precise information on DNA damage. This method can be used in a broad range of clinical, epidemiological, and experimental settings.

Abstract
The detection of mismatched base pairs in DNA plays a crucial role in the diagnosis of genetic-related diseases and conditions, especially for early stage treatment. Among the various biosensors that have been used for DNA detection, EC sensors show great promise because they are capable of precise DNA recognition and efficient signal transduction. Advancements in micro- and nanotechnologies, specifically fabrication techniques and new nanomaterials, have enabled for the development of highly sensitive, highly specific sensors making them attractive for the detection of small sequence variations. Furthermore, the integration of sensors with sample preparation and fluidic processes enables for rapid, multiplexed DNA detection essential for POC clinical diagnostics.

Abstract
Screen-printed carbon electrodes (SPCEs) have been investigated as possible sensors to identify gamma-irradiation induced oxidative damage in double stranded (ds) DNA. Studies were undertaken to explore the possibility of using both cyclic voltammetry and differential pulse voltammetry to identify changes due to oxidative damage. Initially, guanine, adenine and 8-oxoguanosine were examined and it was found possible to differentiate them from their voltammetric responses. The voltammetric response of 8-oxoguanosine was found to be linear over the concentration range 1-400 microM, with a slope of 0.0296 microA microM(-1) (R2 value of 0.9984), in the presence of 2mM concentrations of guanine and adenine. Investigations were made into harnessing these findings to identify oxidative damage in gamma-irradiated dsDNA. The presence of oxidative damage in these samples was readily identifiable, and the magnitude of the voltammetric response was found to be dose dependant (R2=0.9919). A simple sample preparation step involving only the dissolution of double stranded DNA sample in the optimised electrolyte (0.1M acetate buffer pH 4.5) was required. This report appears to be first describing the use of a SPCE to detect DNA damage which can be related to the dose of gamma-radiation used.

Abstract
A novel mixed-ligand nickel(II) complex that contains 1-methylimidazole and thiocyanate, Ni(NCS)(2)(Mim)(4) (Mim=1-methylimidazole), was synthesized and its structure was determined by X-ray crystallography, IR spectrum and elemental analysis, etc. Its DNA-binding properties were studied by electronic absorption spectral, viscositive and electrochemical measurements. The absorption spectral and viscositive results suggest that the nickel(II) complex binds to DNA via partial intercalation. The addition of DNA results in the decrease of the peak current of the nickel(II) complex proved their interaction. The slight differences of peak profiles and electrochemical parameters between free and DNA-bound Ni(NCS)(2)(Mim)(4) showed the formation of an electrochemical inactive complex between Ni(NCS)(2)(Mim)(4) and DNA. The binding site and binding constant of the complex to DNA were determined by electrochemical titration method.

Abstract
This review is devoted to applications of mercury electrodes in the electrochemical analysis of nucleic acids and in studies of DNA structure and interactions. At the mercury electrodes, nucleic acids yield faradaic signals due to redox processes involving adenine, cytosine and guanine residues, and tensammetric signals due to adsorption/desorption of polynucleotide chains at the electrode surface. Some of these signals are highly sensitive to DNA structure, providing information about conformation changes of the DNA double helix, formation of DNA strand breaks as well as covalent or non-covalent DNA interactions with small molecules (including genotoxic agents, drugs, etc.). Measurements at mercury electrodes allow for determination of small quantities of unmodified or electrochemically labeled nucleic acids. DNA-modified mercury electrodes have been used as biodetectors for DNA damaging agents or as detection electrodes in DNA hybridization assays. Mercury film and solid amalgam electrodes possess similar features in the nucleic acid analysis to mercury drop electrodes. On the contrary, intrinsic (label-free) DNA electrochemical responses at other (non-mercury) solid electrodes cannot provide information about small changes of the DNA structure. A review with 188 references.

Abstract
A nanostructured film electrode, a multi-wall carbon nanotubes (MWNT)-modified glassy carbon electrode (GCE), is described for the simultaneous determination of guanine and adenine. The properties of the MWNT-modified GCE were investigated by scanning electron microscopy (SEM) and cyclic voltammetry. The oxidation peak currents of guanine and adenine increased significantly at the MWNT-modified GCE in contrast to those at the bare GCE. The experimental parameters were optimized and a direct electrochemical method for the simultaneous determination of guanine and adenine was proposed. Using the MWNT-modified GCE, a sensitive and direct electrochemical technique for the measurement of native DNA was also developed, and the value of (G+C)/(A+T) of HCl-digested DNA was detected.

Abstract
A flow-injection (FI) device is combined, through the use of a low-volume (4 microl) flow cell, with an ultrasensitive surface plasmon resonance (SPR) spectrometer equipped with a bi-cell photodiode detector. The application of this novel FI-SPR device for sequence-specific ultratrace analysis of oligodeoxynucleotides (ODNs) and polydeoxynucleotides was demonstrated. Self-assembled monolayers of ODN probes are tethered onto Au films with a mercaptohexyl group at the 3' ends. The FI-SPR provides a detection level (< or =54 fM) 2-3 orders of magnitude lower than other SPR devices and compares well with several ultrasensitive detection methods for labeled DNA targets (e.g. fluorophore-tagged and radiolabeled DNA samples). The technique is also highly selective, since a 47mer ODN target with a single-base mismatch yielded a much smaller SPR signal, and a specific interaction was detected when the complementary target was present at 0.001% of the total DNA. The FI-SPR was extended to the measurement of two individual genes in a cDNA mixture transcribed from an Arabidopsis thaliana leaf mRNA pool. The greatly enhanced sensitivity not only obviates the necessity of DNA labeling, but also significantly reduces sample consumption, allowing direct quantification of low abundance mRNAs in cellular samples without amplification.

Abstract
Detection of benzo[a]pyrene diol epoxide (BPDE)-damaged DNA in a human lung carcinoma cell line (A549) has been performed using free zone affinity capillary electrophoresis with laser-induced fluorescence (LIF). Using BPDE as a model carcinogenic compound, the speed, sensitivity and specificity of this technique was demonstrated. Under free zone conditions, an antibody bound adduct was baseline-resolved from an unbound adduct in less than 2 min. The efficiencies of separation were in excess of 6 x 10(5) and 1 x 10(6) plates per meter for the antibody-bound and unbound adducts, respectively. Separation using a low ionic strength buffer permitted the use of a high electric field (830 V/cm) without the loss of resolving power. Using LIF detection, a concentration detection limit of roughly 3 x 10(-10) M was achieved for a 90-mer oligonuleotide containing a single BDPE. The use of formamide in the incubation buffer to enhance denaturing of DNA did not affect the stability of the complex between the antibody and the adducts. Using a fluorescently labeled BPDE-modified DNA adduct probe, a competitive assay was established to determine the levels of BPDE-DNA adducts in A549 cells.

Abstract
Wide-scale DNA testing requires the development of small, fast and easy-to-use devices. This article describes the preparation, operation and applications of biosensors and gene chips, which provide fast, sensitive and selective detection of DNA hybridization. Various new strategies for DNA biosensors and gene chips are examined, along with recent trends and future directions. The integration of hybridization detection schemes with the sample preparation process in a 'Lab-on-a-Chip' format is also covered. While the use of DNA biosensors and gene chips is at an early stage, such devices are expected to have an enormous effect on future DNA diagnostics.

Abstract
Recent trends in the development of DNA biosensors for nucleotide sequence-specific DNA hybridization and for the detection of the DNA damage are briefly reviewed. Changes in the redox signals of base residues in DNA immobilized at the surface of carbon or mercury electrodes can be used as a sign of the damage of DNA bases. Some compounds interacting with DNA can produce their own redox signals on binding to DNA. Covalently closed circular (usually supercoiled) DNA attached to the electrode surface can be used for a sensitive detection of a single break of the DNA sugar-phosphate backbone and for detection of agents cleaving the DNA backbone such as hydroxyl radicals, ionizing radiation, nucleases, etc. Using the peptide nucleic acid in the biosensor recognition layer greatly increased the specificity of the DNA hybridization biosensor making it possible to detect point mutations (single-base mismatches) in DNA.
