Optical sensing has become one of the most active areas of research in bio/chemical and environmental fields, driven by the need for analytical platforms that combine high sensitivity, reliability, and real-time operation with compact and cost-effective implementations. Advances in photonic technologies, functional materials, and data analysis are enabling new sensing concepts capable of addressing challenges in healthcare, environmental monitoring, food safety, and industrial applications.
Among the many approaches currently under investigation, optical fiber technologies continue to play a central role thanks to their versatility and excellent sensing performance. At the same time, emerging photonic platforms—including metasurfaces, optofluidic systems, and integrated optical devices—are expanding the range of available solutions for biochemical sensing. The combination of these platforms with innovative recognition layers, such as biological, biomimetic, and chemical receptors, together with machine learning techniques for signal processing and interpretation, is opening new perspectives for the development of next-generation biosensors.
This webinar will provide an overview of several complementary directions currently shaping the field. The invited presentations will explore recent developments and design challenges in optical fiber grating biosensing, discuss the opportunities offered by Brillouin optical frequency-domain analysis for advanced fiber sensing, and present innovative photonic tools for biochemical sensing. By covering these topics, the webinar aims to highlight both the technological advances and the scientific challenges that are defining the future of optical sensing for bio/chemical and environmental sensing applications.
