Photonics for healthcare

Photonics includes all sciences, technologies and branches that involve light: optics, vision, laser, telecom, etc. It regroups the study and manufacturing of components allowing light generation, detection and manipulation. These devices show significant design advantages: light moves 1014 times faster than electrons and light of certain wavelengths can pass through many biological barriers without undesired interacting.

The photon is the particle of light. The modern concept of photon was developed gradually by Albert Einstein in the early XXth century. Its general definition was adopted in 1926 after a publication of the physical chemist Gilbert N. Lewis in Nature.

What does photonics bring to healthcare?

The use of light has revolutionised biology and medicine several times in History. Back to the XVIIth century, the optical microscope first reset our knowledge of biological tissues, origin of diseases, and our ability to diagnose & cure them. In the last decade, high-resolution combinations of light and electron microscopy allowed to study the structure of biological tissues at a drastically smaller scale, reaching real-time and dynamic visualisation of complex macromolecules like DNA and proteins. Even more recently, biophotonics research has created new solutions for clinical diagnosis and therapies. The current applications of photonics to healthcare are therefore very broad:

  • Ophthalmology deals with the diagnosis and treatment of eye disorders. It indeed uses the photonic optics principle in medicine, from simple medical devices like glasses to laser surgery.
  • Medical imaging is crucial from preclinical research to clinical diagnosis and treatment monitoring as it allows to detect, highlight and track any biological component or micro-organism.
  • Targeted treatments based on light and radiotherapies are vastly used, notably in oncology.
  • Biology manipulation technics like flow cytometry give access to personalized medicine by notably allowing to sort pathologic vs. normal cells of patients.
  • Optical fibre technology has revolutionised communication technologies allowing massive data transfer needed for remote surgery for instance.

    Photonics for healthcare applications

    Improved multi-band (i.e. X-ray, UV, visible, IR, Terahertz)devices

    Various research projects currently develop improved imaging devices to functionally characterise pathologies and to constitute biomarkers database. Optical Coherence Tomography (OCT) or Raman spectroscopy for example allow new laser technologies to perform wide-screening, functional imaging and the constitution of a biomarker database for diagnostics of ocular and neurodegenerative diseases.

    Eye laser surgery is an efficient treatment of vision problems

    LASIK (laser-assisted in situ keratomileusis) is a surgery performed by an ophthalmologist. It uses a laser to reshape the eye’s cornea in order to improve visual acuity. It allows the correction of myopia, hyperopia, and astigmatism and is a long-lasting alternative to eyeglasses or contact lenses.

    Pathogen identification and determination of antibiotics resistance

    Today, bacteria identification is based on cultures, the growth of which takes time. Time, that would be better spent to treat the patient, since survival rates e.g. in case of sepsis, dramatically decrease within the first 48 hours. Optical techniques like Raman spectroscopy will allow to identify bacteria and their resistance within hours, which would drastically increase the survival rate.

    How will NOBEL support the photonics for healthcare community?

    • The European project NOBEL is a Coordination and Support Action (CSA) under Horizon 2020 aiming to help the convergence of photonics with other key enabling technologies with applications in healthcare: nanomedicine, robotics, advanced materials and digital health. NOBEL is coordinated by the ETP-Nanomedicine
    • European Technology Platforms (ETPs) represent each individual technological community at the European level and help bridging those communities with the European Commission. Six ETPs that have applications in healthcare are associated to NOBEL: ETP-Nanomedicine, Photonics21, EU-Robotics, EU-MAT, the European Society of Biomaterials and the ETP for Smart Systems Integration (EPoSS). The NOBEL Project provides them with a meeting space and dissemination by organising annual meetings of their representatives and sharing information from each of them to the HealthTech community
    • The NOBEL Project provides the ecosystem with strategic documents on the future of HealthTech in Europe by combining the inputs of all its Associated Partners in a single vision: the Continuum of Care, a vision for the future of healthcare in Europe
