Uses of Photonics to improve Medicines

The benefits and detriments of sunlight have been known for decades. Researchers are showing that electromagnetic radiation can be the key to safe and effective medical therapies, but only when applied at specific wavelengths and power levels. The application of natural and synthetic forms of electromagnetic radiation formerly called biostimulation but now more commonly known as.

Low-level light therapy (LLLT) or photonic therapy is entirely a matter of wavelength, power level, and duration. The ML 830 is applied for pain management, sports injury, and trigger-point therapy for fibromyalgia, arthritis, and even neuromuscular disorders such as Bell's Palsy. The legitimacy of this therapy and actively investigates the safety, claims, and labeling for all photonic-therapy devices.

Photonics in medical uses

Modern optical endoscopes provide a close-up view of organs and a method for implementing laser surgery, utilizing incisions of less than a few centimeters. In addition, endoscopic visualization is now the standard of care for screening for colon cancer and for diagnosing esophageal cancer. Commonly used today in orthopedic surgery for repairing injuries in almost all of the major joints (knee, elbow, hip, wrist), this technology has allowed many surgeries to become outpatient procedures, eliminating hospital stays and greatly reducing health care costs.

Besides being ubiquitous in the hospital, optical methods and instruments are also used in monitoring chronic conditions and in many outpatient surgical procedures. The most pervasive use of optics and lasers in surgery is in ophthalmology. Laser treatments are standard therapy for treating blindness due to diabetes as well as age-related degenerative disease. One of the most common laser cosmetic surgeries today is the correction of focus of the eye lens by the precise shaping of the cornea, a procedure that has been performed on tens of millions of patients. Lasers and optics are also used in many outpatient elective cosmetic procedures, such as skin resurfacing and hair and tattoo removal.

Wavelength-specific therapies

When discussing LLLT, it is important to distinguish it as the direct application of the laser, LED, or other structured light to a patient for the purpose of offering some healing benefit. Longer infrared wavelengths at 830 nm offer the greatest tissue penetration depth for muscle-healing applications.

The Oralase device from MedX Health (Mississauga, ON, Canada) reduces bleeding, pain, and swelling after dental procedures, and also promotes bone regeneration. Oralase uses a continuous-wave 808 nm, 200mW gallium aluminum arsenide (GaAlAs) laser diode with three red LEDs to guide the infrared healing beam. Another emerging 808 nm application is the noninvasive treatment of ischemic stroke using PhotoThera's (Carlsbad, CA) NeuroThera laser. The even shorter 532 nm wavelength output from a potassium titanyl phosphate (KTP) laser has a profound effect on healing diabetic and other ulcerated open wounds that do not heal after months of traditional treatment with antibiotic and other creams.

New Applications of Photonics by Advance Technology

New optical technology has accelerated the translation of remarkable new capabilities into medical practice. With the introduction of optical methods in the 1980s, the development of superior separation technologies, including capillary electrophoresis and better optical designs using confocal laser scanning.

Increased sequencing speed by about another factor of 10. Recently, single-molecule fluorescence detection during single-strand DNA synthesis, synthesis-based sequencing (SBS), has replaced electrophoresis. Low-noise, high-resolution charge-coupled device (CCD) imaging devices allow the simultaneous sequencing of millions of individual DNA strands.

There is a lot of space to know and improve in photonics. Like: Many chronic, debilitating, and often fatal degenerative diseases impacting the aging population are mediated or exacerbated by the patient's own immune system; Stem cell science is providing great insight into how cells progress from progenitor cells (capable of transforming into any tissue type) to cells of a phenotype characteristic of a specific tissue; Optical techniques using solid-state light sources and detectors. combined with microfluidics are the ideal technology base for automated, low-cost, portable devices that can be operated by personnel without their needing extensive training; etc..

HEALTHCARE!

PHOTONICS is considered as one of the key technologies of the 21st century. At the heart of photonics are technologies for generating light for practical purposes in HEALTHCARE & LIFE SCIENCES. With these technologies, you can understand the aftermath of a concussion. Better with diffusion tensor magnetic resonance imaging. Restore blindness with a PROSTHETIC RETINA. Detect cancer or other illness with a breath test. Treat skin cancer, complexion problems, remove a tattoo, repair damaged neurons, non-invasively with laser etc.
