Biosensors can often diagnose diseases and problems in real-time, reducing the need for invasive treatments or scans. The study of amyloid-beta plaque in the human brain as a precursor to Alzheimer's disease is an example of this.
Fremont, CA: It has been a long time since researchers started manipulating laser technologies in scientific research. This started as scientists started exploring the behavior of light and its interaction with nature. Later it turned into a complete branch of science that is now known as photonics. With every advancement in this branch, scientists discovered how influential photonics was in many scientific discoveries.
Photonics technology spread swiftly from physics to the life sciences. In many stages of medical and biological research, light and laser technologies are used. Spectroscopy enables a more in-depth investigation of biological building pieces, which could change how we view diseases. Medical lasers are used in a variety of applications, including medical imaging and genomics, medication development and delivery, and even robotic surgery guidance.
In this article, let us explore the far-reaching influence of photonics on medicine:
Diagnostic Imaging Devices (OCT, MRI and PET)
Photonics has arguably had the greatest impact on diagnostics in medicine. OCT scans, for example, are a relatively new technology that can identify a wide range of previously undetectable disorders. Ophthalmology was the first and most heavily impacted field to benefit from OCT. Glaucoma, retinopathy, and other kinds of severe visual degeneration can be detected with OCT eye scans. The technique has been vital in diagnosing new retinal disorders and is now a staple in every modern optometry clinic.
Similarly, MRI, CT, and other imaging techniques have aided in the advancement of women's health diagnoses. Replacing cumbersome and intrusive processes with a simple scan reduces the need for cumbersome and invasive procedures.
Biosensors and Biomarkers
Biosensors can often diagnose diseases and problems in real-time, reducing the need for invasive treatments or scans. The study of amyloid-beta plaque in the human brain as a precursor to Alzheimer's disease is an example of this. Injectable nanoscopic sensors and ocular scans are two new technologies that are being developed to investigate the amount of plaque formation. This is a well-known example, but biosensors are being investigated for a variety of conditions, including cancer, HPV, and even some cardiac problems. They have a lot of potentials when combined with photonics and optics technology to address the most serious diseases that affect people's lives.
