Micro And Nano Techniques For The Handling Of Biological Samples

Several micro- and nanomanipulation techniques have emerged in recent decades thanks to advances in micro- and nanofabrication. For instance, the atomic force microscope (AFM) uses a nano-sized tip to image, push, pull, cut, and indent biological material in air, liquid, or vacuum. Using micro- and nanofabrication techniques, scientists can make manipulation tools, such as microgrippers and nanotweezers, on the same length scale as the biological samples. Micro and Nano Techniques for the Handling of Biological Samples reviews the different techniques available to manipulate and integrate biological materials in a controlled manner, either by sliding them along a surface (2-D manipulation), or by gripping and moving them to a new position (3-D manipulation). The advantages and drawbacks are mentioned together with examples that reflect the state-of-the-art in manipulation techniques for biological samples. Thanks to the advances in micro- and nanomanipulation techniques, the integration of biomaterials with physical transducers has been possible, giving rise to new and highly sensitive biosensing devices. Although great progress has been made, challenges are still present. To understand the complex interactions between and inside biological samples, scientists will always be working on improving technologies to manipulate, transport, sort, and integrate samples in different environments. Balanced between simplicity for the beginner and hardcore theory for the more advanced readers, this book is the ideal launching point for sharpening the scientific tools required to address these challenges.

The self-organization of bionanostructures into well-defined functional machineries found in nature has been a priceless source of ideas for researchers. The molecules of life, proteins, DNA, RNA, etc., as well as the structures and forms that these molecules assume serve as rich sources of ideas for scientists or engineers who are interested in developing bio-inspired materials for innovations in biomedical fields. In nature, molecular self-assembly is a process by which complex three-dimensional structures with well-defined functions are constructed, starting from simple building blocks such as proteins and peptides. This book introduces readers to the theory and mechanisms of peptide self-assembly processes. The authors present the more common peptide self-assembled building blocks and discuss how researchers from different fields can apply self-assembling principles to bionanotechnology applications. The advantages and challenges are mentioned together with examples that reflect the state of the art of the use of self-assembled peptide building blocks in nanotechnology.

Research on new sensing concepts has opened the door to a wide variety of microsystems for clinical applications. Such devices are extremely useful for delivering diagnostic information in a fast, simple, and low cost fashion. This book is one of the first to focus on the use of nanotechnology in diagnostics. Designed as a broad survey of the field, this book combines contributions by international experts from divergent fields of study ranging from single molecule diagnostics to cell based systems.

These contribution books collect reviews and original articles from eminent experts working in the interdisciplinary arena of biomaterial development and use. From their direct and recent experience, the readers can achieve a wide vision on the new and ongoing potentials of different synthetic and engineered biomaterials. Contributions were not selected based on a direct market or clinical interest, than on results coming from very fundamental studies which have been mainly gathered for this book. This fact will also allow to gain a more general view of what and how the various biomaterials can do and work for, along with the methodologies necessary to design, develop and characterize them, without the restrictions necessarily imposed by industrial or profit concerns. The book collects 22 chapters related to recent researches on new materials, particularly dealing with their potential and different applications in biomedicine and clinics: from tissue engineering to polymeric scaffolds, from bone mimetic products to prostheses, up to strategies to manage their interaction with living cells.

The manipulation of cells and microparticles within microfluidic systems using external forces is valuable for many microscale analytical and bioanalytical applications. Acoustofluidics is the ultrasound-based external forcing of microparticles with microfluidic systems. It has gained much interest because it allows for the simple label-free separation of microparticles based on their mechanical properties without affecting the microparticles themselves. Microscale Acoustofluidics provides an introduction to the field providing the background to the fundamental physics including chapters on governing equations in microfluidics and perturbation theory and ultrasound resonances, acoustic radiation force on small particles, continuum mechanics for ultrasonic particle manipulation, and piezoelectricity and application to the excitation of acoustic fields for ultrasonic particle manipulation. The book also provides information on the design and characterization of ultrasonic particle manipulation devices as well as applications in acoustic trapping and immunoassays. Written by leading experts in the field, the book will appeal to postgraduate students and researchers interested in microfluidics and lab-on-a-chip applications.

The tools of nanodiagnostics, nanotherapy, and nanorobotics are expected to revolutionize the future of medicine, leading to presymptomatic diagnosis of disease, highly effective targeted treatment therapy, and minimum side effects.

Self-assembled nanostructures based on peptides and proteins have been investigated and presented as biomaterials with an impressive potential for a broad range of applications such as microfabrication, biosensing platforms, drug delivery systems, bioelectronics and tissue reparation. Through self-assembly peptides can give rise to a range of well-defined nanostructures such as nanotubes, nanofibers, nanoparticles, nanotapes, gels and nanorods. However, there are challenges when trying to integrate these biological nanostructures in the development of sensing devices or drug-delivery systems – challenges such as controlling the size during synthesis, the stability in liquid environments and manipulation. In "Micro and Nanofabrication Using Self-assembled Biological Nanostructures" the options and challenges when using self-assembled peptide nanostructures in micro and nanofabrication are discussed. The publication covers different ways to manipulate, deposit and immobilize on specific locations these biological nanostructures in order to use them in the fabrication of new structures or as part of biosensing platforms. Examples where researchers used biological nanostructures for those types of applications are provided. Finally, future applications are discussed as well as parameters to accelerate and expand the use of these biological building blocks in nano- and micro-fabrication processes by taking advantage of their impressive properties such as low-cost and short synthesis time.
