We have come to know that our ability to survive and grow as a nation to a very large degree depends upon our scientific progress. Moreover, it is not enough simply to keep abreast of the rest of the world in scientific matters. 1 We must maintain our leadership. President Harry Truman spoke those words in 1950, in the aftermath of World War II and in the midst of the Cold War. Indeed, the scientific and engineering leadership of the United States and its allies in the twentieth century played key roles in the successful outcomes of both World War II and the Cold War, sparing the world the twin horrors of fascism and totalitarian communism, and fueling the economic prosperity that followed. Today, as the United States and its allies once again find themselves at war, President Truman’s words ring as true as they did a half-century ago. The goal set out in the Truman Administration of maintaining leadership in science has remained the policy of the U.S. Government to this day: Dr. John Marburger, the Director of the Office of Science and Technology (OSTP) in the Executive Office of the President made remarks to that effect during his confirmation hearings in October 2 2001.

This interdisciplinary book covers the fundamentals of optical whispering gallery mode (WGM) microcavities, light–matter interaction, and biomolecular structure with a focus on applications in biosensing. Novel biosensors based on the hybridization of WGM microcavities and localized surface plasmon resonances (LSPRs) in metal nanoparticles have emerged as the most sensitive microsystem biodetection technology that boasts single molecule detection capability without the need for amplification and labeling of the analyte. The book provides an ample survey of the physical mechanisms of WGMs and LSPRs for detecting affinity, concentration, size, shape and orientation of biomarkers, while informing the reader about different classes of biomolecules, their optical properties and their importance in label-free clinical diagnostics. This expanded and updated second edition features a new chapter that introduces the reader to advanced in vivo biosensing techniques using WGM microcavities, looking at photothermal sensing, methods for trapping neutral atoms around WGM microcavities, and practical aspects of optoplasmonic sensing. The second Edition now provides a comprehensive introduction to the use of WGM microcavities in physical sensing which includes measurements with frequency combs, macro and micro (one atom) lasers, gyroscopes, optomechanical and parity-time-symmetric sensor devices. Chapter-end problems round out this comprehensive and fundamental textbook, inspiring a host of up-and-coming physicists, bioengineers, and medical professionals to make their own breakthroughs in this blossoming new field. This textbook can be used for both introductory and advanced courses about the modern optics of optical microcavities.

The transduction of unreadable chemical/biological components to readable optical or electrochemical signals utilizing different biosensing technologies is one of the important pathways of understanding the principles of nature. To achieve this ambitious goal, many biosensors have been developed to obtain useful information from complex systems (e.g. cells, tissues, and humans) ever since the first glucose biosensor was invented in 1967. Nowadays, biosensors are spread all over every branch of frontier science ranging from fundamental measurement science to advanced artificial intelligence technology. Although many transduction technologies are available so far, optical and electronic signals are still two of the most commonly used techniques as the detectable outputs for biosensors. Taking advantage of the development of additive manufacturing techniques such as 3D printing and the improved understanding of the biomolecules, optical and electrochemical biosensing technologies have also been developed on their sensitivity, selectivity and speed. In view of the fast development in the area, we propose a Research Topic focused on the recent development of optical and electrochemical biosensing. The topics of the Research Topic cover various optical and electrochemical biosensors, which potentially promote the revolution of modern measurement techniques. Notably, this issue will not only cover the topics in individually used optical or electrochemical biosensors but also receive interconnection techniques between optical and electrochemical signals. We welcome submissions in the following themes, but not limited to: • Fundamental studies of the optical and electrochemical biosensing • Optical biosensing techniques • Electrochemical biosensing techniques • Combined optical and electrochemical biosensors • Commercializing of the optical and electrochemical biosensors • In vivo and in vitro optical and electrochemical biosensing
