Being a tremendously inter-disciplinary subject, nanotechnology which comprises of life sciences, materials science, and engineering sciences shines out as the upcoming field in many industries. Nanoparticles that are of 10-9 in size act as a bridge between mass materials and atomic structures. That is the reason of why they form a great scientific attention. To define on the whole, nano-science comprises the basic sciences like physics, biology and chemistry and understanding their properties on atomic and molecular scales. Nanotechnology occupies controlled manipulation of the atomic properties to make materials to exhibit their exclusive capabilities.

One such industry in which nanoparticles are used is the food industry. Nanotechnology is soon to set its foot in food industry and futuristically speaking, the science will be utilized in food production and also for food detection. Broadly Nanoscience is the wide subject providing ample opportunities as the production of less waste using less sized particles is the need of our hour where environment is a must to be taken into account. Nanotechnological companies are on high roads in the field of food production already.

The expected impact of nanotechnological methods, machines, and products is to be extensive and frankly speaking, Nanotechnologies have the potentials to proffer exciting promises which will benefit the society as a whole. But it is important to consider both pros and cons of the technology. The darker side of the nanoparticles is that they can cause brain damage. The recent studies with the rats have proved this which is equivalent to Alzheimer's disease.

The primary effect is to the workers working in Nanotech companies. There is a possibility of health risks and this is unconventional. That means we need to practice some practices in the industries which can provide safety measures. The presence of engineered nanoparticles in the workplace today fronts an instant challenge to safety measure controls to manage the workers? health.

It is throbbing when we listen to experts and their researches stating that companies spend billions of money for the research and leave away just a few million for the whole safety and regulatory measures. Finally it is required to put in a serious investment in safety measures for a field of nanotechnology risk research.
