Today, nanotechnology is becoming the new and popular way to improve health care. Evidence is accumulating that nanotechnology may enable better early warning systems for cancer and heart disease, cures for progressive diseases like cystic fibrosis, techniques for making implants like artificial hips more successful, and even artificial kidneys. In the medical field, the scale is so small involving living cells and viruses that range in size from 20 nanometers to 300 nanometers. For this reason, medical research has long worked on the nanoscale. Dr. H. David Humes at the University of Michigan and Dr. Tejal Desai at Boston University are using machinery and processes to build prototypes of implantable artificial organs with pores or slits smaller than 20 nanometers wide.
Nanoparticles are used by researchers to overcome obstacles in gene therapy, which are predicted to cure genetically inherited diseases such as cystic fibrosis by implanting healthy genes to help cure or replace the spot of the damaged genes. Nanoparticles can also be used to kill cancer cells by heating them. According to MagForce Technologies by using nanotechnology allows the nanoparticles to destroy tumor cells by coating iron oxide nanoparticles with a compound that is a nutrient for tumor cells. After an external magnetic field vibrates the particles rapidly, the tumor cells are killed and the scavenger cells flush them out of the body.
This new technology is predicted to be a controversial method in curing many health related issues; however this new technology faces many technical issues and repeating failures by delaying the development nanotechnology. "The complexity of biology is clearly beyond our comprehension at this time," said Dr. James R. Baker Jr.
