Today, healthcare problems have become the most essential and challenging matters worldwide. Many features in biomedical industries have been growing quickly in recent years, particularly in the underdeveloped areas.

The plasmonic-optical fiber sensors have shown extraordinary capabilities in realizing highly sensitive and accurate sensors for the measurement of biological analytes in the field of health monitoring and diagnosis.

This kind of sensor offers a unique ability for real-time monitoring of the molecular binding events. Plasmonics in optical fiber is a highly dynamic field feeding to multi-faceted research domains and involves several students, researchers, scientists, and engineers from different areas. The sensitivity of plasmonic structures to the changes in their local dielectric environment has led to the development of new sensing strategies and systems. It is a huge topic for many areas that need more than even research to increase the strength of this digital Era.

This Research Topic on “Optical Fiber-based Plasmonics Biosensors for Biomedical Applications” have contribution of papers in Frontiers in Sensors, Physical Sensors, Biosensors and Frontiers in Physics, Optics and Photonics and it was organized by Managing Editor Santosh Kumar, Liaocheng University, China and Guest Editors Carlos Marques, Qiang Wu, Qinglin Wang, and Sanjeev Kumar Raghuwanshi. The goal is to highlight the advancement of optical fiber-based plasmonics biosensors and devices in applications to sensors covering fields such as medicine, power industry, energy, fast optics and telecom. The Research Topic includes both comprehensive review articles and original technical contributions covering fundamental research and application. 17 invited feature papers will be published in this issue where the authors are from universities, government labs and industries.

The managing editor, Santosh Kumar, and guest editors thank the authors who submitted their papers to this Research Topic and the anonymous reviewers whose feedbacks ensure the high quality of the Journal, the Frontiers publication team, for helping this issue to be a success.

All Guest Editors hope that this special issue can provide and in-depth look at this hot-topic where future students, researchers, engineers and industrial applicators can take a valuable reference on Optical Fiber-based Plasmonics Biosensors for Biomedical Applications.
