Medicine has been around since the interception of life itself, but as always Medicine is changing.
As years go by we have switched from orthodox medicine to ingestible drugs, and right now the future of medicine is nanomedicine. Medicine cannot change completely because some illness will still require orthodox methods of treatment but nanomedicine provides a new means where active ingredients can be digested using unconventional means. In nanomedicine, we will be seeing more of biological sensors and medical devices.
What is Nanomedicine?
As the name implies, nanomedicine is the application of nanotechnology principles and nanomaterials to medicine. In a real sense, its principles are also applied in many areas of biology, chemistry, and pharmacy. In pharmacy, there are so many areas where they have incorporated the principles of nanotechnology, especially in drug delivery systems.
The drug delivery systems work for conventional drug delivery solvent and many of these drugs are programmed and tailored to deliver in a specific location and even to specific cancerous tissues. They do not make a mistake to program this drugs to deliver to healthy tissues. Liposomes, colloidosomes are a few of the many novel systems that can trap active drug ingredients inside nanostructure and safely deliver them at their desired target without causing any harmful effect to the body.
One of the most successful areas where nanomedicine has been developed is in the creation and administering of 3-dimensional nanovaccines. During the administration of these nanosized rods, the rods are injected under the skin of a patient, whereupon they assemble into a 3-dimensional structure. These nanosized rods are made up of series of nano-pores that release chemical messenger molecules and antigens that activate dendritic cells within the body. These cells then diffuse out of the rods and into the body, where they alert the white blood cells and invoke an immune response. The key thing with these vaccines is that the chemicals and antigens can be changed in the nanorods, meaning that this vaccine method could be used for multiple diseases.
A few of the basic areas of nanomedicine is written here, they are just the most common in a whole range of new medical treatments that use nanotechnology. You can be assured that nanomedicine will not take over traditional pharmaceutical medicine, instead, it is going to compliment it and fill in the gaps where conventional pharmaceuticals are ineffective.
