Abstract
Nanobiotechnologies, from the convergence of nanotechnology and molecular biology and postgenomics medicine, play a major role in the field of public health. This overview summarizes the potentiality of piezoelectric sensors, and in particular, of quartz-crystal microbalance (QCM), a physical nanogram-sensitive device. QCM enables the rapid, real time, on-site detection of pathogens with an enormous burden in public health, such as influenza and other respiratory viruses, hepatitis B virus (HBV), and drug-resistant bacteria, among others. Further, it allows to detect food allergens, food-borne pathogens, such as Escherichia coli and Salmonella typhimurium, and food chemical contaminants, as well as water-borne microorganisms and environmental contaminants. Moreover, QCM holds promises in early cancer detection and screening of new antiblastic drugs. Applications for monitoring biohazards, for assuring homeland security, and preventing bioterrorism are also discussed.

Abstract
Viruses have recently proven useful for the detection of target analytes such as explosives, proteins, bacteria, viruses, spores, and toxins with high selectivity and sensitivity. Bacteriophages (often shortened to phages), viruses that specifically infect bacteria, are currently the most studied viruses, mainly because target-specific nonlytic phages (and the peptides and proteins carried by them) can be identified by using the well-established phage display technique, and lytic phages can specifically break bacteria to release cell-specific marker molecules such as enzymes that can be assayed. In addition, phages have good chemical and thermal stability, and can be conjugated with nanomaterials and immobilized on a transducer surface in an analytical device. This Review focuses on progress made in the use of phages in chemical and biological sensors in combination with traditional analytical techniques. Recent progress in the use of virus-nanomaterial composites and other viruses in sensing applications is also highlighted.

Peptide-coated nanotube-based biosensor for the detection of disease-specific autoantibodies in human serum. Biosens Bioelectron 2007; 23:1413-21. [PMID: 18222083 DOI: 10.1016/j.bios.2007.11.022] [Citation(s) in RCA: 69] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2007] [Revised: 11/17/2007] [Accepted: 11/23/2007] [Indexed: 11/20/2022]
Abstract
We demonstrate a label-free peptide-coated carbon nanotube-based immunosensor for the direct assay of human serum. A rheumatoid arthritis (RA)-specific (cyclic citrulline-containing) peptide, was immobilized to functionalized single-walled carbon nanotubes deposited on a quartz crystal microbalance (QCM) sensing crystal. Serum from RA patients was used to probe these nanotube-based sensors, and antibody binding was detected by QCM sensing. Specific antibody binding was also determined by comparing the assay of two serum control groups (normal and diseased sera), and the native unmodified peptide. The sensitivity of the nanotube-based sensor (detection in the femtomol range) was higher than that of the established ELISA and recently described microarray assay systems, detecting 34.4 and 37.5% more RA patients with anti-citrullinated peptide antibodies than those found by ELISA and microarray, respectively. There was also an 18.4 and 19.6% greater chance of a negative test being a true indicator of a person not having RA than by either ELISA or microarray, respectively. The performance of our label-free biosensor enables its application in the direct assay of sera in research and diagnostics.

Abstract
Results from an investigation of the frequency response resulting from ligand binding for a genetically engineered hormone-binding domain of the alpha-estrogen receptor immobilized to a piezoelectric quartz crystal are reported. Two different approaches were used to attach a genetically altered receptor to the gold electrode on the quartz surface: (1) the mutant receptor containing a single solvent-exposed cysteine was directly attached to the crystal via a sulfur to gold covalent bond, forming a self-assembled protein monolayer, and (2) the N-terminal histidine-tagged end was utilized to attach the receptor via a 3,3-dithiobis[N-(5-amino-5-carboxypentyl)propionamide-N',N'-diacetic acid] linker complexed with nickel. Previous studies have shown that these engineered constructs bind 17beta-estradiol and are fully functional. Exposure of the receptor directly attached to the piezoelectric crystal to the known ligand 17beta-estradiol resulted in a measurable frequency response, consistent with a change in conformation of the receptor with ligand binding. However, no response was observed when the receptor immobilized via the linker was exposed to the same ligand. The presence of the linker between the quartz surface and the protein receptor does not allow the crystal to sense the conformational change in the receptor that occurs with ligand binding. These results illustrate that the immobilization strategy used to bind the receptor to the sensor platform is key to eliciting an appropriate response from this biosensor. This study has important implications for the development of QCM-based sensors using protein receptors.

Abstract
A dense virus layer, readily tailored for recognition of essentially any biomarker, was covalently attached to a gold electrode surface through a self-assembled monolayer. The resistance of this "virus electrode", Z(Re), measured in the frequency range from 2 to 500 kHz in a salt-based pH 7.2 buffer, increased when the phage particles selectively bound either an antibody or prostate-specific membrane antigen (PSMA), a biomarker for prostate cancer. In contrast to prior results, we show the capacitive impedence of the virus electrode, Z(Im), is both a noisier and a less sensitive indicator of this binding compared to Z(Re). The specificity of antibody and PSMA binding, and the absence of nonspecific binding to the virus electrode, was confirmed using quartz crystal microbalance gravimetry.

Abstract
In this work, we describe a method of constructing a film of linear poly(glycidyl methacrylate) (PGMA) polymer onto the surface of quartz crystal microbalance (QCM) electrode as a coating material that allows easy coupling of heparin molecules onto the electrode and facilitates the determination of the interaction between heparin and antithrombin III (AT III). The PGMA film was characterized with atomic force microscopy (AFM) and infra-red spectroscopy. The coupling of heparin was accomplished in one step solution reaction. A home-made quartz crystal microbalance-flow injection analysis (QCM-FIA) system with data analysis software developed in our laboratory was used to determine the interaction. The interactions between immobilized heparin and AT III were studied with various concentrations under various conditions. The obtained constants are kass=(1.49+/-0.12)x10(3)mol-1ls-1, kdiss=(3.94+/-0.63)x10(-2)s-1, KA=(3.82+/-0.33)x10(4)mol-1l.

Abstract
A quartz crystal microbalance (QCM) biosensor integrated into a flow injection analysis (FIA) system was used for the real-time investigation of molecular recognition between a protein and small molecular medicinal agents. Two sulfa-drugs, sulfamethazine (SMZ) and sulfamethoxazole (SMO), were, respectively, immobilized on the gold electrodes of the piezoelectric crystals using appropriate procedures based on self-assembly of the dithiothreitol (DTT). The binding interactions of the two immobilized drug ligands, with various proteins in solution, were followed as changes in the resonant frequency of the modified crystals. Results obtained from this rapid screen analysis clearly indicated that the two drug ligands appeared quite different in this molecular recognition procedure although their structures were similar. SMZ-immobilized sensor showed specific interaction only with IgG, while SMO-immobilized sensor showed negligible specific binding with IgG, but binding with trypsin and chymotrypsin. Further studies on the specific interaction between immobilized SMZ and three different species of IgG--human IgG, goat IgG and mouse IgG were carried out and the marked species-dependent difference was observed. The resultant sensorgrams were rapidly analyzed by using an in-house kinetic analysis software based on genetic algorithm (GA) to derive both the kinetic rate constants (kass and kdiss) and equilibrium association constants (KA) for IgG-SMZ interactions. For the interactions, KA were 5.48 x 10(5), 2.75 x 10(5) and 1.86 x 10(5) M(-1) for human IgG, goat IgG and mouse IgG, respectively. The kinetic data provided further insight into the structural/functional relationships of different IgG on a molecular level.

Abstract
We developed a quartz crystal biosensor designed to detect concentrations and ligand affinity parameters of free unlabeled proteins in real time. Using a model system with human IgE as the analyte and single-stranded DNA aptamers or an anti-IgE antibody as immobilized ligands, we could demonstrate that aptamers were equivalent to antibodies in terms of specificity and sensitivity. Both receptor types selectively detected 0.5 nmol/L of IgE. In addition, the aptamer receptors tolerated repeated affine layer regeneration after ligand binding and recycling of the biosensor with little loss of sensitivity. Because of the small size and nonprotein nature of the aptamers, they were immobilized in a dense, well-oriented manner, thus extending the linear detection range to 10-fold higher concentrations of IgE. In addition to demonstrating for the first time that an aptamer-based biosensor can specifically and quantitatively detect an analyte in various complex protein mixes, the aptamer-ligand proved to be relatively heat resistant and stable over several weeks. Since aptamers consist of nucleic acids, well-established chemistry can be applied to produce optimized affine layers on biosensors that may be developed to specifically detect proteins in solution for analysis of proteomes.

Abstract
Biosensors based on phage display-derived peptides as biorecognition molecules were used for the detection of cell surface cross-species markers in tissue homogenates. The peptide selected for murine myofibers was immobilized onto the surface of an acoustic wave sensor by biotin-streptavidin coupling. To detect peptide-receptor interaction, the sensors were exposed to muscle and control (kidney, liver, brain) tissue homogenates. The sensor showed a strong response to murine muscle. The amplitudes of the responses to the feline muscle homogenates were lower compared to those of the murine muscle, while the same K(d) indicated that the peptide has cross-species affinity. In contrast, murine kidney, liver and brain homogenates produced insignificant responses. Specificity of the sensor was shown in a blocking experiment, as reduced signal was detected when muscle preparations were preincubated with free peptide. Additionally, when muscle-specific peptide was replaced with two different random control peptides, the sensors produced no response to murine muscle. Suitability of peptide ligands for a variety of species can be evaluated using this technology.
