Download or read book Label Free Biosensors written by Matthew A. Cooper and published by Cambridge University Press. This book was released on 2009-02-02 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Label-free biosensors are devices that use biological or chemical receptors to detect analytes (molecules) in a sample. They give detailed information on the selectivity, affinity, and, in many cases, also the binding kinetics and thermodynamics of an interaction. Although they can be powerful tools in the hands of a skilled user, there is often a lack of knowledge of the best methods for using label-free assays to screen for biologically active molecules and accurately and precisely characterize molecular recognition events. This book reviews both established and newer label-free techniques giving both the expert user and the general reader interested in the technologies and applications behind label-free an insight into the field from expert opinion leaders and practitioners of the technologies. Most importantly, chapters contain worked examples from leaders in the field that take the reader through the basics of experimental design, setup, assay development, and data analysis.

Download or read book Label free and Multi parametric Monitoring of Cell based Assays with Substrate embedded Sensors written by Maximilian Oberleitner and published by Springer. This book was released on 2017-09-26 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes novel substrate embedded physical sensors that can be used to monitor different types of cell-based assays non-invasively and label-free. The sensors described provide integrative information of the cells under study with an adaptable time resolution (ranging from milliseconds to days). This information about the dynamic cell response to chemical, physical or biological stimuli defines a new paradigm in fundamental biomedical research. The author, Maximilian Oberleitner, describes approaches in which the cells are directly grown on different sensor surfaces (gold-film electrodes, shear wave resonators or dye-doped polymer films). This approach, with the reacting cells in particularly close proximity and contact with the sensor surface, is key to a remarkable sensitivity, opening the way for a variety of new applications. This thesis not only introduces the fundamentals of each approach, but it also describes in great detail the design principles and elucidates the boundary conditions of the new sensors.

Download or read book Label Free Monitoring of Cells in vitro written by Joachim Wegener and published by Springer Nature. This book was released on 2019-11-18 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to label-free, non-invasive monitoring of cell-based assays and it comprises the most widely applied techniques. Each approach is described and critically evaluated by an expert in the field such that researchers get an overview on what is possible and where the limitations are. The book provides the theoretical basis for each technique as well as the most successful and exciting applications. Label-free bioanalytical techniques have been known for a long time as valuable tools to monitor adsorption processes at the solid-liquid interface in general – and biomolecular interaction analysis (BIA) in particular. The underlying concepts have been progressively transferred to the analysis of cell-based assays. The strength of these approaches is implicitly given with the name 'label-free': the readout is independent of any label, reagent or additive that contaminates the system under study and potentially affects its properties. Thus, label-free techniques provide an unbiased analytical perspective in the sense that the sample is not manipulated by additives but pure. They are commonly based on physical principles and read changes in integral physical properties of the sample like refractive index, conductivity, capacitance or elastic modulus to mention just a few. Even though it is not implied in the name, label-free approaches usually monitor the cells under study non-invasively meaning that the amplitude of the signal (e.g. electric field strength, mechanical elongation) that is used for the measurement is too low to interfere or affect. In contrast to label-based analytical techniques that are commonly restricted to a single reading at a predefined time point, label-free approaches allow for a continuous observation so that the dynamics of the biological system or reaction become accessible.

Available in PDF, EPUB and Kindle. Book excerpt: Biomedical optical imaging is a rapidly emerging research area with widespread fundamental research and clinical applications. This book gives an overview of biomedical optical imaging with contributions from leading international research groups who have pioneered many of these techniques and applications. A unique research field spanning the microscopic to the macroscopic, biomedical optical imaging allows both structural and functional imaging. Techniques such as confocal and multiphoton microscopy provide cellular level resolution imaging in biological systems. The integration of this technology with exogenous chromophores can selectively enhance contrast for molecular targets as well as supply functional information on processes such as nerve transduction. Novel techniques integrate microscopy with state-of-the-art optics technology, and these include spectral imaging, two photon fluorescence correlation, nonlinear nanoscopy; optical coherence tomography techniques allow functional, dynamic, nanoscale, and cross-sectional visualization. Moving to the macroscopic scale, spectroscopic assessment and imaging methods such as fluorescence and light scattering can provide diagnostics of tissue pathology including neoplastic changes. Techniques using light diffusion and photon migration are a means to explore processes which occur deep inside biological tissues and organs. The integration of these techniques with exogenous probes enables molecular specific sensitivity.

Download or read book Holographic Sensors written by Ali Kemal Yetisen and published by Springer. This book was released on 2014-12-03 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a theoretical and experimental approach for the rapid fabrication, optimization and testing of holographic sensors for the quantification of pH, organic solvents, metal cations, and glucose in solutions. Developing non-invasive and reusable diagnostics sensors that can be easily manufactured will support the monitoring of high-risk individuals in any clinical or point-of-care setting. Sensor fabrication approaches outlined include silver-halide chemistry, laser ablation and photopolymerization. The sensors employ off-axis Bragg diffraction gratings of ordered silver nanoparticles and localized refractive index changes in poly (2-hydroxyethyl methacrylate) and polyacrylamide films. The sensors exhibited reversible Bragg peak shifts, and diffracted the spectrum of narrow-band light over the wavelength range λpeak ≈ 495-1100 nm. Clinical trials of glucose sensors in the urine samples of diabetic patients demonstrated that they offer superior performance compared to commercial high-throughput urinalysis devices. Lastly, a generic smartphone application to quantify colorimetric tests was developed and tested for both Android and iOS operating systems. The sensing platform and smartphone application may have implications for the development of low-cost, reusable and equipment-free point-of-care diagnostic devices.

Download or read book Advancing the Biosensing Technologies of Two Optical Label free Sensing Platforms written by Rashmi Sriram and published by . This book was released on 2015 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Optical label-free biosensors promise high-throughput, rapid, and sensitive detection of biomolecules. As such, these biodetection platforms have applications in clinical diagnostics, pharmaceutical industry, homeland security and in environmental monitoring. Motivated by these attributes, my thesis has focused on advancing the biosensing technology of two novel silicon-based optical label-free sensors: arrayed imaging reflectometry (AIR) and two-dimensional photonic crystal structures (2D PhC). The AIR biosensor is an interferometry-based technique that relies on the creation and destruction of a near-zero reflectivity condition in a carefully chosen thin film. To thoroughly quantify the biosensor detection signal, a correlation between the sensor response and the solution analyte concentration needs to be determined. In the first half of this thesis, a theoretical framework was developed to predict the AIR sensor response for a given solution analyte concentration. The developed model was subsequently validated using spectroscopic ellipsometry and surface plasmon resonance techniques in addition to AIR by utilizing two model probe-analyte pairs. It was established that the probe-analyte interaction on AIR substrate across two formats: macrospots and microarrays closely represented one-site and two-site Langmuir models, respectively. Two-dimensional photonic crystals are periodic dielectric structures with spatial periodicity in two dimensions. In the presence of a "defect" microcavity that disrupts the spatial periodicity, light of specific wavelength can be captured within the defect cavity. This manifests as a "dip" in the transmission spectrum of the crystal and is very sensitive to the local refractive index changes in the immediate vicinity of the defect cavity. The second half of this thesis investigates the utility of two designs of the 2D PhC: "small" and "large" point-defect microcavities coupled to a transmission waveguide for sensing latex particles in microfluidic environment. With the "small" defect design, detection of ~100 nm size latex particles in microfluidic environment was confirmed. This is the first study that demonstrates particle detection in the presence of a fluid cover using a 2D PhC sensor, a significant technological advancement for the incorporation of this sensor into lab-on-a-chip device. Using a "large" point-defect cavity design, real-time detection of latex particles of size ~280 nm was demonstrated. This to our knowledge is the first demonstration of detection of latex particles in real-time using 2D PhCs without the aid of any optical forces. This proof-of-principle demonstration of particle detection lays the foundation for the further development of these devices for the detection of a single biological particle, which when accomplished will have a huge impact in the field of clinical diagnostics"--Pages ix-x.
