Optical Sensors for Biomedical Diagnostics and Monitoring

Dear Colleagues,

Optical sensing technologies are transforming the landscape of biomedical diagnostics and health-monitoring systems. With their unique advantages—high sensitivity, rapid response, non-invasive operation, and compatibility with compact and wearable platforms—optical sensors have become indispensable tools across clinical medicine, personalized healthcare, and physiological monitoring. Recent progress in photonic materials, micro/nano-optical structures, fiber-optic technologies, and optical signal-processing methods has further accelerated the development of innovative biomedical sensing modalities capable of detecting subtle biochemical, metabolic, and biomechanical changes within the human body.

The aim of this Special Issue is to provide a timely platform for showcasing the latest breakthroughs in optical sensor materials, device architectures, and biomedical applications. We welcome contributions that span fundamental technological innovations, system-level integration, and practical demonstrations in diagnostic or monitoring scenarios. Original research articles, communications, and comprehensive reviews are all encouraged. Topics of particular interest include, but are not limited to, the following:

• Design and engineering of optical sensing materials and photonic structures for biomedical use;
• Fiber-optic, waveguide-based, or micro/nano-optical sensors for physiological and biochemical monitoring;
• Optical imaging and spectroscopy techniques for disease detection and health assessment;
• Wearable, implantable, or minimally invasive optical sensing platforms;
• Signal processing, machine learning, and intelligent algorithms for optical biosensing and diagnostics;
• Multimodal sensing systems integrating optical signals with mechanical, electrical, or chemical readouts;
• Demonstrations of optical sensor applications in clinical diagnostics, health monitoring, rehabilitation, and telemedicine.

We hope this Special Issue will inspire new ideas and foster interdisciplinary collaborations that further advance the use of optical sensors in biomedical science and healthcare.
