What Is Nanomedicine

nanomedicineNanomedicine term refers to the application of nanotechnology in the field biological devices, nanoelectronic bio sensors, molecular nanotechnology and biological machines. The contemporary researchers struggle with the issues that involve the toxicity and the impact these materials have on the environment.

The molecules manipulated by these scientists have more or less the same size as the biological structures and molecules. The similarity of sizes makes it possible to nanomaterials to be used in in vitro research and application.

The National Nanotechnology Initiative has set the goals to research, develop and implement as many tools and devices in the future. The latest research is looking into administrating drugs in the human body with a targeted delivery. The problem that scientists try to solve is the maximization of the medication delivery. The current drug delivery, either by pills or injectable has a lower efficiency in administrating the medicine to the correct and intended medication. With the help of nanotechnology, tests are already being made on successfully delivering the drugs to the targeted regions in the body, releasing the medication at the intended destination, thus eliminating the possibility that body parts receive a medication it does not need.

Tests with gold nanoshells are already being made on mice. This type of treatment is intended to locate and treat cancer, by finding the sick cells and acting against them. This method is good because it uses the specific medication only on the infected cells, thus minimising the poisoning of the entire organs or cells around the sick area.

This method is awaiting to start human trials in the near future and if successful, to start using it for patient suffering of cancer.

A different path of nanomedicine is the development of small electromechanical systems, that travel through the human body, investigate certain areas, identify the problems and map the area for the drug delivery in the correct spot.
