Photonics applications in healthcare replace specific invasive and complex diagnostic and treatment procedures.
FREMONT, CA: Photonics is an essential application in the healthcare industry. Healthcare equipment leverages photonics' non-invasive properties and its high-speed movement while biological barriers are without causing complications. Biological tissues absorb light during imaging and cancer screenings. Photons in laser equipment and biomedical techniques are ideal for tissue incisions, heating and vaporizing specific tissue regions, and sealing wounds.
Bioactive macromolecules absorb specific wavelengths that flag the physiological conditions of organs. Engineered dyes and biomarkers apply light to marked cell types like cancer cells.
Disease diagnosis: Photonics technology selectively detects biomarkers, metabolites and metabolic biomarkers, pathogens, and disease-specific changes in cell and tissue composition and body fluids. Photonic applications in optical imaging techniques detect diffraction, refraction, scattering, and absorption of light by the tissue.
Multi-modal approaches to photonic applications analyze structural changes associated with specific disorders in morphological imaging. Functional imaging analyzes metabolism, cell composition, and blood flow. Optical imaging methods like endoscopy, optical coherence tomography (OCT), microscopy, and spectroscopy detect microscopic and macroscopic malignancies.
Ophthalmology departments and institutions utilize photonics to identify changes in the physical structure of the eye by obtaining high-resolution three-dimensional images of the retina using OCT. It flags structural changes indicative of glaucoma and macular degeneration.
Fluorescent endoscopy detects and differentiates small tumors of 1 mm diameter from healthy tissues. In cancer detection, fluorescent probes like peptide and nanoparticulate probes bind to identifiable tumor biomarkers with higher accuracy.
Disease treatment: Photonics-based treatment procedures deliver treatment measures quickly, especially in laser radiation. Physicians can scale treatment intensities to meet diagnostic requirements and severity by adjusting the radiation's wavelength, intensity, and duration. In cancer treatments, diffraction-limited laser scans smaller locations. Trends in scattered and absorbed light provide information about tumors at the cellular and sub-cellular levels. Surgeons prefer to use photon-based equipment for short laser bursts. Surgeons can avoid lengthy and complicated surgical procedures, blood loss, and surgery-related pain.
Researchers are combining artificial intelligence with photonic technologies to differentiate malignant tissues from benign tissues in any stage of cancer. Photonics applications are expanding with the deployment of Biophotonic cancer therapies like endoscopy-assisted surgery, photoablation, photothermal ablation, plasma-induced laser ablation, and photo-disruption.
