This book provides a one-stop solution to the latest advanced microscopic and spectroscopic techniques for investigating a range of important polysaccharides and is an ideal reference for researchers in the field of biophysics, molecular biology, biochemistry, pharmaceutics, food chemistry and related areas.

This book focuses on polarization microscopy, a powerful optical tool used to study anisotropic properties in biomolecules, and its enormous potential to improve diagnostic tools for various biomedical research. The interaction of polarized light with normal and abnormal regions of tissue reveals structural information associated with its pathological condition. Diagnosis using conventional microscopy can be time-consuming, as pathologists require an hour to freeze and stain tissue slices from suspected patients. In comparison, polarization microscopy more quickly distinguishes abnormal tissue and provides better microstructural information of samples, even in the absence of staining. This book provides a basic understanding of the properties of polarized light, a description of the polarization microscope, and a mathematical formalism of Mueller matrix polarimetry. The authors discuss various advanced linear and nonlinear optical techniques such as optical coherence tomography (OCT), reflectance and transmission spectroscopy, fluorescence, multiphoton excitation, second harmonic generation, Raman microscopy, and more. They explore the exciting potential of integrating polarimetry with these techniques for possible applications in different areas of biomedical research, as well as the associated challenges. Including the most recent developments on the topic, this book serves as a modern guide to polarization microscopy and advancements in its use in biomedical research.

The book reviews the recent developments in brain imaging and their technological advancements to understand molecular mechanisms associated with neurological disorders and basic behaviors in humans and rodents at the structural, molecular, and functional levels. It discusses the usefulness of advanced optical microscopy techniques, including optical coherence tomography (OCT), miniscope, multiphoton fluorescence (2PF & 3PF), adaptive optics, harmonic generation, and Raman microscopy for understanding pathomechanism of brain disorders and pathological and physiological changes associated with neurodegenerative diseases. Also, the book presents conventional imaging modalities, including Magnetic Resonance Imaging (MRI), for delineating underlying mechanisms and precise early diagnosis of neurological disorders. This book is a useful resource for neuroscientists and researchers working in biomedical engineering and optics.

Collagen is the most abundant protein class in the human body. The polymer also has the distinct benefit of being biodegradable, biocompatible, readily accessible, and very adaptable. The use of collagen-based biomaterials in tissue engineering applications has increased dramatically over the past few years, owing to extensive research in the field. Multiple cross-linking strategies for collagen have been examined. Various combinations of collagen with other biopolymers have also been investigated in an attempt to increase the tissue function of the collagen biomaterials in their various formulations. Collagen Biomaterials provides a thorough overview of the different uses of collagen-based biomaterials produced for tissue engineering, to offer a functional material for use in regenerative medicine from the laboratory bench to the patient bedside.
