Nanotechnology
The future of healthcare doesn’t lie solely in things like large MRI machines and huge surgical facilities; it is being created on the atomic/molecular level. Nanotechnology, or working with materials at the nanometer level (1 to 100 nanometers), is no longer a futuristic concept — it is at the forefront of a new medical revolution that will provide more precise, less invasive and more effective ways to treat patients.
The Benefits of Using Nanotechnology
-
Delivering Medicines Precisely:
Unlike the traditional system of delivering medicines to the whole body in order to get to one organ; nanoparticles provide a means of delivering ‘intelligent couriers’ of drug/medication directly to the site. -
Development of diagnostics, new methods of diagnosis:
Quantum dots and gold nanoparticles have the ability to replace traditional dyes as contrast agents in imaging and can therefore be utility to assist clinicians in detecting diseases such as Alzheimer’s and early stage tumour prior to the availability of images via conventional imaging (e.g., X-ray, MRI).
-
Development of regenerative medicine:
The potential impact of nanotechnology has vast implications in treating and repairing individuals with spinal cord injuries and even for those individuals that have sustained severe burns.
Outlook:
Despite the enormous benefits of this technology, there is much to be achieved in order for the mangled healing of mankind to become a reality. We must understand the nanotoxicity associated with the manufacture and use of nano-made materials as well as their long-term effects on the human immunology system.
Closing Thoughts:
Nanotechnology is altering the medical model from “responding to illness through treatment” to “anticipating sickness by preventative methods.” The future holds some of the most impactful devices that will alter the biological processes of the human body without being visible.
conclusion :
What aspect of nanotechnology do you see as the most promising and/or concerning over the next ten years in your practice or in your research? Are you convinced the “smart pill” will succeed in eliminating your need for traditional surgical methods, or is there an unknown consequence by intervening on a molecular level?
