Introduction

Nonmaterial pose new challenges to laboratory safety: for example, they have been shown to have the potential to infiltrate healthcare products. Development of evaluation models to assess the health and safety risks of nanostructures is critical to both protect human health and to assure the public that nonmaterial's can be handled safely. Current uncertainties for risk assessment of nanostructures arise due to lack of an acceptable model that accommodates the wide range of physical characteristics of nanostructures (i.e., size, shape, and surface charge), variation in cell models, and growing media, as well as limited information on toxic kinetics and toxicology. The available data on exposure to specific engineered nonmaterial's and consequently toxicity is extremely limited; the majority of the available information on toxicity of nonmaterial's is from in vitro studies, while the limited in vivo studies available cover only a narrow range of particles. The interdisciplinary nature of much nanotechnology research also makes it difficult to impose a single set of rules for lab research, since researchers from different disciplines are accustomed to different procedures and regulations. In addition, nanotechnology is not a single technology so much as it is an approach to manipulating and creating substances while working on a very small scale, one that is used in many settings, from university research labs to factories producing consumer products, each with their own priorities and customs regarding safety regulation.

Discussion

Physical and chemical properties of nonmaterials makes the same material or from a macro-scale chemical substance is dissolved, it provides a new addition to the extensive application, they may cause different changes in reaction kinetics and toxicity profile. For non-physical properties of substances are the main parameters of size distribution, shape, chemical composition, solubility, surface properties (charge, composition), and the presence of impurities. Reduce the surface area of ??the nano-particle size increased dramatically, until the number of surface molecules, making it dominate the surface characteristics. Very high for non-material surface area, the situation in the risk assessment needs to consider some of the effects, because it makes them different from the macroscopic counterparts. (Powell, Kanarek , 2006)

The increased activity of nanoparticles with the surface of bulk materials, the more molecules, because the nanoparticle surface in the strongly unstable. High surface energy and surface forces may bring instability of the anti-particle interactions. Therefore, particles tend to freedom of reunion, in the larger particles, can be saved, such as high surface area of ??nanoparticles and the reaction of some of the properties. Tendency to unite the nanoparticles surface modification can enhance or hinder. (Meyer,2005)

Use gloved hands to prevent microbial contamination and infection. In the user or invasive procedures reviewed, there may be health professionals, contact with blood or body fluids potentially infectious. Professionals who do not wear gloves, in these cases can be easily infected wounds, puncture or broken skin. Similarly, staff who are infected and those who maintain body cleansing treatment equipment and other objects have the same risk of contamination of clinical ...
