Bioresorbable Fiber Bragg Grating sensor advances medicine

on December 17, 2018

Today environmental change provokes the appearance of new diseases and, finally, human health care requirements continue increasing during several decades. Moreover, it is necessary to have new advanced tools for the disease diagnosis at early stages, for monitoring and treatment of patients. Then unconventional biomedical instrumentation and sensors, including optical-fiber sensors come for help to modern medicine. And devices with bioresorbable fiber sensors increase the efficiency of monitoring and treatment.

Fiber Bragg Grating (FBG) is one of the most productive way suggested for fiber-based biomedical sensing. Fiber Bragg grating sensing technology provides a new and effective way of real-time measurements. The fields of FBGs application contain biosensing, safety or security and structural-health monitoring. Also FBG sensors are highly suitable for laser systems, medical tiny intra-aortic probes and body sensors for biochemical analysis making.

Modern Fiber Bragg Gratings use bioresorbable optical-fiber sensing probes that have such ability as controlled solubility in physiological environment. A bioresorbable material is the main component of FBG sensors and human body easily and safely assimilates it at a special time interval. The technology allows safer diagnostic of sensitive human organs and there is no need for a surgery extraction. Fiber Bragg Gratings sensors are easy to install and use, their sensing points have quite high density. It is an ideal, cost effective and accurate technology for extreme environmental conditions.

The advantages of optical fiber include:

  • good mechanical durability;
  • high optical transmission;
  • stoichiometrically tunable dissolution rate.

It should be mentioned that tilted Bragg gratings with 1-degree tilt angle that are immersed in phosphate buffered saline solution with temperature and pH conditions similar to those of the human body allow fiber dissolution studying. Finally, selective chemical-etching effects were found out thanks to scanning electron microscope images and micro-Raman spectroscopy.

Thus, bioresorbable fiber Bragg grating sensor are considered to be effective for the development of soluble, compact photonic sensing probes that can be used for in vivo monitoring of vital mechanical or chemical factors with a specific time limit, and also in controlled in-body drug delivery.
