Book Description
Molecular recognition, also known as biorecognition, is the heart of all biological interactions. Originating from protein stretching experiments, dynamic force spectroscopy (DFS) allows for the extraction of detailed information on the unbinding process of biomolecular complexes. It is becoming progressively more important in biochemical studies and is finding wider applications in areas such as biophysics and polymer science. In six chapters, Dynamic Force Spectroscopy and Biomolecular Recognition covers the most recent ideas and advances in the field of DFS applied to biorecognition: Chapter 1: Reviews the basic and novel aspects of biorecognition and discusses the emerging capabilities of single-molecule techniques to disclose kinetic properties and molecular mechanisms usually hidden in bulk measurements Chapter 2: Describes the basic principle of atomic force microsocopy (AFM) and DFS, with particular attention to instrumental and theoretical aspects more strictly related to the study of biomolecules Chapter 3: Overviews the theoretical background in which experimental data taken in nonequilibrum measurements of biomolecular unbinding forces are extrapolated to equilibrium conditions Chapter 4: Reviews the most common and efficient strategies adopted in DFS experiments to immobilize the interacting biomolecules to the AFM tip and to the substrate Chapter 5: Presents and discusses the most representative aspects related to the analysis of DFS data and the challenges of integrating well-defined criteria to calibrate data in automatic routinary procedures Chapter 6: Overviews the most relevant DFS applications to study biorecognition processes, including the biotin/avidin pair, and selected results on various biological complexes, including antigen/antibody, proteins/DNA, and complexes involved in adhesion processes Chapter 7: Summarizes the main results obtained by DFS applied to study biorecognition processes with forthcoming theoretical and experimental advances Although DFS is a widespread, worldwide technique, no books focused on this subject have been available until now. Dynamic Force Spectroscopy and Biomolecular Recognition provides the state of the art of experimental data analysis and theoretical procedures, making it a useful tool for researchers applying DFS to study biorecognition processes.

Book Description
The highly specific recognition processes between biomolecules mediate various crucial biological processes. Uncovering the molecular basis of these interactions is of great fundamental and applied importance. This research work focuses on understanding the interactions of several biomolecular recognition systems and processes that can provide fundamental information to aid in the rational design of sensing and molecular recognition tools. Initially, a reliable and versatile platform was developed to investigate biomolecular interactions at a molecular level. This involved several techniques, including biomolecule functionalization to enable attachment to self-assembled monolayers as well as atomic force microscopy (AFM) based force spectroscopy to uncover the binding or rupture forces between the receptor and ligand pairs. It was shown that this platform allowed determination of molecular binding between single molecules with a high specificity. The platform was further adapted to a general sensing formulation utilizing a group of flexible and adaptive nucleic acid recognition elements (RNA and DNA aptamers) to detect specific target proteins. Investigation of interactions at the molecular level allowed characterization of the dynamics, specificity and the conformational properties of these functional nucleic acids in a manner inaccessible via traditional interaction studies. These interactions were then adapted to aptamer-based detecting methods that at the ensemble or bulk scale, specifically taking advantage of mechanisms uncovered in the biophysical study of this system. A quartz crystal microbalance (QCM) was used to detect protein targets at the bulk level and the affinities and binding kinetics of these systems were analyzed. Along with AFM-based force spectroscopy, ensemble-averaging properties and molecular properties of these interactions could be correlated to contribute to bridging the gap across length scales. Finally, more broadly applicable sensing platform was developed to take advantage of the unique properties of aptamers. DNA was employed both as a carrier and as a molecular recognition agent. DNA was used as a template for nanoconstruction and fabricating unique shapes that could enhance the aptamer-based molecular recognition strategies. With aptamers tagged to distinct nanoconstructed DNA, a novel shape-based detecting method was enabled at the molecular level. The results demonstrated that this is a flexible strategy, which can be further developed as ultrasensitive single molecule sensing strategy in complex environments.
Correlation Force Spectroscopy for Single Molecule Measurements
Author: Milad RadiomPublisher: Springer
ISBN: 3319140485
Category : Science
Languages : en
Pages : 135
Book Description
This thesis addresses the development of a new force spectroscopy tool, correlation force spectroscopy (CFS) for the measurement of the properties of very small volumes of material (molecular to μm3) at kHz-MHz frequency range. CFS measures the simultaneous thermal fluctuations of two closely-spaced atomic force microscopy (AFM) cantilevers. CFS then calculates the cross-correlation in the thermal fluctuations that gives the mechanical properties of the matter that spans the gap of the two cantilevers. The book also discusses development of CFS, its advantages over AFM, and its application in single molecule force spectroscopy and micro-rheology.
