Transcript

  • 1. Nanotechnology in Surgery
    Louizos Alexander Louizos
    ΜSc Nanotechnology & Nanosciences
    PhD candidate in Nanomechanics
    Resident in Vascular Surgery
  • 2. What is NanoTech ?
    Tech for objects in the size scale of < 100 nm
    Nanomedicine Nanotechnology in Medicine
  • 3. “Nature is our playground through a holistic synthetic approach to science”.
    Biological Material, DNA synthesis
    MechanicalProperties
    NOVEL MATERIALS THROUGH NOVEL APPROACH TO SCIENCE
    Chemistry & SurfaceScience
    Optical Properties
    Electronic Properties
    Electron Microscopy, AFM
  • 4. Who is the oldest Nanotechnologist?
  • 5. Mother Nature has had 4.5 billion years to play with inorganic matter and build nanomachines that prove the feasibility of nanotechnology in medicine
    FACT THAT LED TO BIOMIMETIC TECHNOLOGY
  • 6. Surgery
    Surgeons operate in the macro scale.
    We promote the self healing of the body so we do not heal. The reason for the tissue malfunction is on molecular basis
    All surgeons (almost all ) know that the more gentle you are with the tissue the less the complications
    We need lessons from nature on how to heal
    gently and elegantly from the bottom up!
  • 7. Trends in surgery
    We created better tools to assist our hands
    We begun to be less invasive: Laparoscopic tools , endovascular treatments
    We created robotic hands that are performing better than human hand: Da Vinci Robotic Surgery
    We are now experimenting with microrobots ( I will show you some of them)
    We will finally move to the nanorobotics technology
    SEEMS BIT FRUSTRATING
    FOR YOUR TRAINING AS A SURGEON 
    The only thing that saves us is the time lag between
    experimental phase, clinical trials and widespread use of methods
  • 8. Robots in Surgery
    Da Vinci Robotic Surgery
    Mag-μbot
    Endoscopy Capsule
    Mag-μRobot (Carnegie Mellon )
  • 9. Nanorobots
    When and how?
    In about 10-20 years but we do not know how they will be like.
    We presume them to be like natural nanomechines (e.g. mitochondria)
  • 10. Lab On A Chip
    • No need for an angry (why did you awake me up in the middle of the night) microbiologist.
    • 11. Multiple exams on a small scale machine
    • 12. Minimal invasive: less blood for the same exams
    • 13. Can be preventive in nature – Self assessment by patients
  • Nanoparticle Assisted Surgery
    Targeted nanoparticles to specific tumors will provide visual guide for the right tissue removal (not too much, not too little).
    No need for histological tissue exam of the extremities of the oncectomy.
  • 14. The Ideal Grafts
    Enhanced Biocompatibility through Biomimetism of nanotopography (still needing surgery for transplantation, hint: Future surgical specialties will be boosted toward transplantation of every possible human part)
    Artificial Grafts are mistaken for Real Tissue if they look like tissue
    We should still embed “if they function like tissue”
    Future of Grafts 3D Printing and Stem Cells
    The future may be towards “transcendence” meaning hacking of our physiological evolutionary path towards an enhanced man – machine hybrid. (possibly in the next 50 years)
  • 15. Tissue Engineering - Bioprinting
    Bioprintingcan be defined as computer-aided, automatic, layer-by-layer deposition, transfer, and patterning of biologically relevant materials.
  • 16. Potential Dangers of Nanomedicine
    D.I.Y. Bio: Biotechnology tools on the hands of ordinary people through the miniturization of devices
    Nanoparticles not yet deeply studied in terms of toxicity and safety
    Great Goo-> uncontrolled self replicating nanorobots
