Abstract
In the last two decades, there has always been a hunt for reliable, costeffective, and environmentally friendly processes for manufacturing nanomaterials to decrease the usage of dangerous chemicals affecting human life. There is always a debate about whether the industry is beneficial/nonbeneficial for human life. To answer this question, we have summarized the negative aspects of nanomaterials that have been used on numerous synthesized routes in laboratories and studied the journey of these particles from lab to industry.
