NanoToxicology



Abstract

Nano materials are very special in the form of their properties. They are very fast reacting, having high surface area and they have higher than usual penetration power. However, these properties are also going against living beings affecting human and other animals' health. Particles gets entered into body either by accidently or by intentionally. In the body ultimately most of the nano material affects DNA functionality and lead to abnormal protein production. There is mentioning of two studies in this paper. One is regarding Ti02 effect upon p53 gene. This proves that Ti02 has adverse effects deviation p53 functionality. The other study is of Carbon Nano tubes . This study also emphasizes upon inhalational adverse effect of CNT in rats. There are some suggestions for modification of current methods in research also.Although, there is not sufficient data regarding mortality and morbidity due to nano particle toxicity, we cannot deny its adverse effects upon living beings like us. Those studies which are mentioned in this paper have shown some evidence about ill effects of nano particles and bagging some serious research in to this matter. Each day a new nanotechnology arrives with new nano particles, which are not yet know may have new kind of effects and may be serious after a long time.Methods for determination of toxicity should be changed according to nanotechnology development and other needs. In vitro test are more cost and time effective and there are no ethical issues. Also improving in vitro techniques would increase accuracy of test and so results

Introduction

This paper narrates the information about nanotoxicology. Nanotoxicology is a study of nano materials. There is information regarding current usage forms of nano particle in different technologies in different field. Nano materials are very special in the form of their properties. They are very fast reacting, having high surface area and they have higher than usual penetration power. However, these properties are also going against living beings affecting human and other animals' health. Particles gets entered into body either by accidently or by intentionally. In the body ultimately most of the nano material affects DNA functionality and lead to abnormal protein production. There is mentioning of two studies in this paper. One is regarding Ti02 effect upon p53 gene. This proves that Ti02 has adverse effects deviation p53 functionality. The other study is of Carbon Nano tubes . This study also emphasizes upon inhalational adverse effect of CNT in rats. There are some suggestions for modification of current methods in research also.

Toxicology is a study of toxicity of particles sized between 0 to100 nanometer. Study of toxicity caused by nanoparticles is mandatory to determine whether nanomaterial is detrimental to environment and so to human beings. Nanoparticles generally are used in medicines, electronics and biomaterials.(Candice,2013)
