This image was obtained using a Scanning Electron Microscope. It shows gold nanoparticles of various sizes and shapes. Note that individual atoms of gold can be seen as well as the boundaries between different crystal organizational regions of the nano particles. These boundary regions may prove important in understanding the strength of the nano particle. Suppose now that instead of a bowling ball rolling along, we follow a red blood cell traveling through the blood stream. Instead of the billiard ball, imagine a drug coated nanoparticle made up of several hundred gold atoms.

Can we calculate the path of the cell and the nanoparticle after they collide using the same approach we used with the bowling and billiard balls, or should we take into account other mechanisms such as the viscosity of the blood? Is it possible that the interaction between the much larger red blood cell and the small nano particle may convey sufficient energy to the nanoparticle so that the bonding force between its atoms would be overcome and the nanoparticle would fall apart?

At the present time the answer to such questions is not always fully known, and such scenarios are studied by nanoscience researchers and practitioners. Nanoscientists are asking questions like, "How do atoms behave differently than ,? Or "Can we weigh proteins and viruses? Most importantly, the information and knowledge required to answer these questions does not come for only one or two disciplines - it requires a combination of knowledge, investigative and experimental skills from all of the disciplines.

In the nanoscience research and product development arena many of the understanding and discoveries are coming about because of the interaction and synergistic efforts of multi-disciplinary teams. As implied above, we have a good understanding of how many things work and interact at the macro or micro scale but the understanding is less clear when we start observing the interaction of individual molecules or atoms. This is especially true, and even more so for biological systems. Although answers are being found daily, we do not know the exact interaction mechanism for a drug and various proteins, or how the ion channels in cell membranes "decide' whether to open or close.

The foundational cause of most diseases is fundamentally unknown. This is where the tools of nanotechnology enter into the picture.

Researchers are using the tools of nanoscience; atomic force microscope AFM , scanning electron microscope SEM , transmission electron microscoe TEM and so on to understand how biological systems work at the molecular level. The image to the right shows the hairs inside the ear of a turtle. By taking images like this we can begin to understand the chemical, electrical and physical operation of very small, complex biological systems. The bundle in this hair cell is a pyramidal structure composed of sterocilia, which are connected by tip links. When the bundle is displaced, the tip links get stretched and pull open the transduction channels, thereby generating an electrical signal due to positively charged ions.

Myosin motor proteins attached to the channels may be involved in active amplification. Using nanoscience tools such as a nano mechanical indenter, researchers are studying the interface between the sponge-like dentin region and the hard enamel portion of a tooth. This understanding will lead to better dental care, treatment and protection materials. As researchers begin to understand the molecular level operation of biological systems we can then begin to replicate those systems using tools and methods of chemistry, physics, materials science, and engineering.
