Gold Nanoshells and Cancer Treatment

Cancer represents a major concern not only in the medicine area, but in all the science sectors around the globe. Now, nanotechnology is leading the area of research development thanks to some new discoveries that allow the scientific community to see the light at the end of the tunnel. In previous research, the creation of…

Titanium Dioxide for Photocatalytic Decontamination

Water decontamination using titanium dioxide (TiO2) as photocatalyst is being used in some places around the world. Under ultraviolet light (UV) the TiO2 reacts with organic pollutants due to it strong oxidative potential. It is also demonstrated that with natural sunlight the TiO2 can degrade the 4-chlorophenol pollutant from water[1]. Also other water contaminant can…

Nanotechnology: Janus Particles

Recently, the synthesis of Janus particles has created great interest in the scientific field. These particles received its name in allusion to the double-faced Roman god Janus; for this reason the particles with two chemically or physically different surfaces, receive the name of Janus particles. Synthesized particles with different properties present new opportunities for many…

Machines at very small scales

What is a machine? And why do we need them? The scientific definition of a “machine” is any device that transmits or modifies energy. In common usage, the meaning is restricted to devices that have rigid moving parts that perform, or assist in performing some work (see Concise Oxford Dictionary), although animals, including humans, and…
