Light, Life and Control: Optogenetics, Light-Sensing Moss, and Bio-Inspired Detection Systems: Fundamentals of Light, Life, and Biological Control

Light, Life and Control: Optogenetics, Light-Sensing Moss, and Bio-Inspired Detection Systems explores the fascinating relationship between light, living organisms, and emerging technologies. The book presents an interdisciplinary perspective connecting photobiology, molecular biology, cellular signalling, optogenetics, and bio-inspired sensing systems. It explains how light acts not only as an energy source but also as a biological signal that regulates cellular activities, gene expression, growth, and physiological responses.

The initial chapters introduce the fundamental properties of light, including wavelength, frequency, and intensity, and examine how light interacts with biological matter. The book discusses photoreception and light-driven biological processes, highlighting the mechanisms through which living systems detect and respond to different wavelengths of light. It also introduces biological control mechanisms, cellular communication, signal transduction, feedback regulation, and gene expression, establishing the scientific foundation for understanding light-controlled biological responses.

A major focus is placed on biological photoreceptors, including phytochromes, cryptochromes, phototropins, and Light-Oxygen-Voltage (LOV) domains. Their structural characteristics, light-sensing mechanisms, and functional roles are explored to explain how organisms convert optical signals into biochemical and physiological responses. The discussion further considers the engineering of photoreceptor proteins for applications in optogenetics and other light-responsive technologies.

By connecting natural biological mechanisms with engineered control systems, the book establishes a foundation for understanding how biological light-sensing principles can inspire innovative detection, monitoring, and control technologies. It is intended for students, researchers, and professionals in electronics and communication engineering, biotechnology, biological sciences, biomedical engineering, photonics, and artificial intelligence who are interested in the convergence of light-based science and emerging technological applications.

Overall, the book aims to bridge the gap between fundamental biological principles and technological innovation, demonstrating how the study of light-sensitive living systems can contribute to the development of intelligent, responsive, and bio-inspired systems.
