In traditional medical examination theory, optical fibers made of glass fiber are generally used to transport light into the body.
However, once people use glass optical fibers to penetrate deep into biological tissues, glass is brittle and non-biodegradable.
Implantation into the body will destroy and damage tissue.
And for medical examinations such as laser surgery, drug activation, optical imaging, disease diagnosis, and optogenetics (an experimental field that uses light to manipulate the function of brain neurons), glass optical fibers are not suitable for transmitting information. Realistic.
ADSS Optical Cable This time, electrical engineers and biomaterials engineers from the Institute of Materials at Pennsylvania State University developed a degradable optical fiber. It is a citrate-based polymer, a key component of natural metabolism.
Develop this polymer into a general platform for biomedical applications such as biodegradable bone screws for bone fixation, scaffolds for tissue engineering, and nanoparticles for delivering time-release therapeutics. Created a step-index optical fiber for light propagation in the human body to achieve ultra-fine adjustment of the refractive index difference between the core and cladding to facilitate organ-sized light transmission and collection.
This optical fiber will bring new experiences in information transmission, imaging and detection in human tissue examination.
