Book Description
The recent increase in survival rates of most cancers is due to early detection greatly aided by medical imaging modalities. Combined ultrasound and photoacoustic imaging provide both morphological and functional/molecular information which can help to detect and diagnose cancer in its earliest stages. However, both modalities can benefit from the use of contrast agents. The objective of this thesis was to design, synthesize, and test a nano-sized, dual contrast agent for combined ultrasound and photoacoustic imaging named Photoacoustic nanoDroplets. This agent consists of liquid perfluorocarbon nanodroplets with encapsulated plasmonic nanoparticles. These dual contrast agents utilize optically triggered vaporization for photoacoustic signal generation, providing significantly higher signal amplitude than that from the traditionally used mechanism, thermal expansion. Upon pulsed laser irradiation, liquid perfluorocarbon undergoes a liquid-to-gas phase transition generating giant photoacoustic transients from these dwarf nanoparticles. Once triggered, the gaseous phase provides ultrasound contrast enhancement. Demonstrated in this work are the design, synthesis, characterization, and testing of Photoacoustic nanoDroplets in phantom and animal studies, and preliminary work into adapting these agents into targeted, drug delivery vehicles for simultaneous detection, diagnosis, and treatment of diseases.

Book Description
Photoacoustic and Photothermal Spectroscopy: Principles and Applications introduces the basic principles, instrumentation and major developments in the many applications of Photoacoustic and Photothermal Spectroscopy over the last three decades. The book explains the processes of sound generation by periodic optical excitation and ultrasonic generation by pulsed laser excitation and describes the workings of photoacoustic cells equipped with microphones and piezoelectric transducers. Photoacoustic imaging (PAI) is one of the fastest-growing imaging modalities of recent times. It combines the advantages of ultrasound and optical imaging techniques. These non-invasive and non-destructive techniques offer many benefits to users by enabling spectroscopy of opaque and inhomogeneous materials, (solid, liquid, powder, gel, gases) without any sample preparation, and more. Written in a non-mathematical, simple-to-read manner Presents recent developments in the field, along with the scope of future progress, including up-to-date references Includes detailed illustrations, such as equipment layout, spectra, experimental setups, tables, photographs, and more

Book Description
This book describes medical applications of photochemistry. In the first part, a general introduction to photochemistry and related phototechnologies is provided. In the second part, photochemistry-based medical applications for diagnostics (biochips and bioimaging) and therapeutics (biomaterials for artificial organs, medical adhesives, dental materials, drug-delivery systems, tissue engineering, and photodynamic therapy) are described, with examples of recent research. The year 2015 is the International Year of Light and Light-Based Technologies. Light plays a vital role in our daily lives and is important in many interdisciplinary scientific fields in the twenty-first century. Light-based concepts have revolutionized medicine, including areas such as oncology, molecular biology, and surgery. Although photochemistry has contributed significantly to medicine directly and through photochemical fabrication of biomaterials, a book giving a comprehensive overview of recent progress has not been published until now. The aim of this book is to highlight the contributions of photochemistry in interdisciplinary fields of chemistry and medical engineering. This book will be useful for chemists who are interested in medical applications of photochemistry and engineers who are eager to learn the principles of photochemistry to enable its use in practical applications.

Book Description
This thesis covers a broad range of interdisciplinary topics concerning electromagnetic-acoustic (EM-Acoustic) sensing and imaging, mainly addressing three aspects: fundamental physics, critical biomedical applications, and sensing/imaging system design. From the fundamental physics perspective, it introduces several highly interesting EM-Acoustic sensing and imaging methods, which can potentially provide higher sensitivity, multi-contrast capability, and better imaging performance with less distortion. From the biomedical applications perspective, the thesis introduces useful techniques specifically designed to address selected challenging biomedical applications, delivering rich contrast, higher sensitivity and finer spatial resolution. Both phantom and ex vivo experiments are presented, and in vivo validations are progressing towards real clinical application scenarios. From the sensing and imaging system design perspective, the book proposes several promising sensing/imaging prototypes. Further, it offers concrete suggestions that could bring these systems closer to becoming “real” products and commercialization, such as replacing costly lasers with portable laser diodes, or integrating transmitting and data recording on a single board.
