Biosensor techniques are based on biospecific interaction between the biological parts of biosensor with the analyte. In biosensor construction, antibodies are usually used for the detection of analytes such as microorganism, because of very strong and highly specific interaction. The disadvantages of this assay are a long time needed for antibody isolation and purification as well as difficult regeneration of biosensor chip. The use of lectins instead of antibodies could solve these problems because a several hundred lectins are commercially available and their stability in standard buffers is better compared to monoclonal antibodies. While antibody can only be used to detect that antigen it was designed for, lectin as low affinity molecule may bind several different pathogens. Using the discriminative effect of an artificial neural network the application of a lectin array will compensate for the lower specificity. Microbial surfaces bear many of the sugar residues capable of interacting with lectins. The ability of lectins to react with microbial glycoconjugates means that it is possible to employ them as probes and sorbents for whole cells, mutants and numerous cellular constituents and metabolites, and it makes them useful tools for identification or typing of bacteria. Lectins are attractive reagents for the clinical diagnostic laboratory because of their diverse specificity, commercial availability, a wide range of molecular weights, and their stability in standard buffers. The construction of lectin biosensor could be an advantage method for detection of pathogenic bacteria.

The interaction of nanotechnology and biosciences opens the possibility for a wide variety of biological research topics and day-to-day applications at the molecular and cellular level. In particular, nanotechnology has been revolutionizing the area of biosensor. Nanobiosensor, an integration of physical sciences, molecular engineering, biology, chemistry and biotechnology holds the possibility of detecting and manipulating atoms and molecules using nanodevices, which have the potential for a wide range of both industrial and domestic applications. The role of electrochemical nanobiosensor in food analysis is an important and interesting area. This review covers the basic principles and types of electrochemical biosensor formats, role of nanomaterials for biosensor and reported food-specific applications of electrochemical nanobiosensors.

Yeast as a biosensor for antioxidants: simple growth tests employing a Saccharomyces cerevisiae mutant defective in superoxide dismutase

Mutants of Saccharomyces cerevisiae devoid of Cu,Zn-superoxide dismutase are hypersensitive to a range of oxidants, hyperbaric oxygen and hyperosmotic media, show lysine and methionine auxotrophy when grown under the atmosphere of air and have a shortened replicative life span when compared to the wild-type strain. Ascorbate and other antioxidants can ameliorate these defects, which may be a basis of simple tests sensing the presence of antioxidants. In particular, tests of growth on solid medium (colony formation) in the absence of methionine and/or lysine, or in the presence of 0.8 M NaCl can be useful for detection and semiquantitative estimation of compounds of antioxidant properties. Hypoxic atmosphere was found to increase the sensitivity of detection of antioxidants. The test of abolishment of lysine auxotrophy showed a concentration dependence of the antioxidant effects of cysteine and N-acetylcysteine which, however, lost their protective action at high concentration, in contrast to glutathione which was effective also at higher concentrations.

Glycophorin A (GPA), the major sialoglycoprotein of the human erythrocyte mem­brane, was isolated from erythrocytes of healthy individuals of blood groups A, B and O using phenol-water extraction of erythrocyte membranes. Interaction of individual GPA samples with three lectins (Psathyrella velutina lectin, PVL; Triticum vulgaris lectin, WGA and Sambucus nigra I agglutinin SNA-I) was analyzed using a BIAcore™ biosensor equipped with a surface plasmon resonance (SPR) detector. The experi­ments showed no substantial differences in the interaction between native and desialylated GPA samples originating from erythrocytes of either blood group and each of the lectins. Desialylated samples reacted weaker than the native ones with all three lectins. PVL reacted about 50-fold more strongly than WGA which, similar to PVL, recognizes GlcNAc and Neu5Ac residues. SNA-I lectin, recognizing α2-6 linked Neu5Ac residues, showed relatively weak reaction with native and only residual reac­tion with desialylated GPA samples. The data obtained show that SPR is a valuable method to determine interaction of glycoproteins with lectins, which potentially can be used to detect differences in the carbohydrate moiety of individual glycoprotein samples.

Nano-biosensors could be defined as biosensors, which are combined with nanotechnology by using several techniques. This strategy could be seen as a key to yielding device which exhibits rapid responses combined with very high sensitivities. In recent years as consumer demand traceability and legislators and accountability in the food chain distribution has increased, the need for rapid and verifiable methods of food quality assurance has grown rapidly. Sensing technologies for food analysis including optical, chromatographic, colorimetric, etc. are employed. Biosensors allow the detection of analyte’s wide spectrum in complex sample matrices, and have shown great promise in areas such as food analysis, environmental monitoring and bioprocess. Biosensors can be divided into six groups which depend on the method of signal transduction: magnetic, optical, electrochemical, mass, thermal and micromechanical sensors. The aim of this paper is to present the directions of the development of nano-biosensors and their useability to detect a range of biological and chemical compounds in the food industry market.
