Filling Gel for Optical Fiber Cable
"Human Fiber" in vivo transmission of information can be automatically degraded
Recently, an article was published in the magazine "Biomaterials". The electrical engineer of the Materials Research Institute of Pennsylvania State University and the biological material engineer showed the latest work. A flexible, biodegradable fiber can transmit light into the human body. In this experiment, citrate polymers were used to create a step-index optical fiber for light transmission in the human body.
In traditional medical examination theory, glass fiber-based optical fibers are generally used to deliver light into the body. However, if people use glass fiber to penetrate into biological tissues, the glass is brittle and not biodegradable. Implantation destroys and damages tissue. And for medical examinations such as laser surgery, drug activation, optical imaging, disease diagnosis, and optogenetics (the experimental field where light is used to manipulate brain neuronal functions), glass fiber optics transmit information unrealistically. filling gel for optical fiber cable.
This time, the degradable fiber developed by electrical engineers and biomaterials engineers at the Pennsylvania State University Material Research Institute is a citrate-based polymer that is a key component of natural metabolism. Develop this polymer as a general platform for biomedical applications, such as bone-immobilized biodegradable bone screws, tissue-engineered stents, and nanoparticles for the delivery of time-release therapeutics, which create light for human body transmission. A step-index fiber that is used to achieve ultra-fine adjustment of the refractive index difference between the core and the cladding, promoting light transmission and collection at the organ size level. This kind of fiber will bring new experiences for information transmission, imaging and detection in human tissue inspection.filling gel for optical fiber cable
Due to the same mechanical properties of the core and the cladding, such fibers can be bent and stretched, and similar situations can occur between different materials. And after the completion of optical information transmission, imaging and detection, the core and cladding materials of the optical fiber will be biodegraded at the same rate in vivo, and will not cause secondary damage to human tissues. filling gel for optical fiber cable .
The author of the article stated that this new type of biodegradable, biocompatible, and low-loss step-index optical fiber is still in the laboratory stage, ready to go deep into the biological tissue. After success, not only can it complete the transmission, detection and imaging of medical optical information, but it can also add therapeutic chemicals, drugs or biological molecules for disease treatment.
