Cinnamon, a spice commonly found in the kitchen able to present a more simple and secure way to make gold nanoparticles. According to research, cinnamon particles that can even be used to treat cancer.
For information, gold nanoparticles were known to be very useful for detecting tumors, performing a search of oil, street lights and cure diseases. Unfortunately, the process of making particles that require hazardous chemicals. Currently, there are several ways to make gold nanoparticles.
But the ways in which generally involves dissolving chloroauric acid, also called a gold salt, in the liquid and adding other chemicals to precipitate the gold atom. Other common mixtures such as using sodium citrate, sodium borohydrida (which is also used to bleach wood pulp) and ammonium compounds, all of which can be harmful to humans and the environment.
In order to promote environmentally friendly nanotechnology, researchers from the University of Missouri gold salt mixing with cinnamon. When combined with nanoparticles, this phytochemical substances can enter and destroy cancer cells or help with mapping for more accurate medical procedure can be applied. "
Our gold nanoparticles are not only healthy ecology and biology, but they are also biologically active against cancer cells," said Kattesh Katti, professor of radiology and physics from the University of Missouri School of Medicine.
As quoted from PopSci, January 5, 2011, the process of making particles that do not require electricity and chemicals in addition to the basic materials of gold salts.
In a report published in the journal of Pharmacy Research, Katti said that cinnamon and seeds, leaves and other spices can be used to convert metal into nanoparticles without using harmful chemicals. "Approach 'green' nanotechnology suggests that we use nature's role can not be ignored in the future development of nanotechnology," says Katti.
