Green Nanotechnology: The Influence of Intermolecular and Supramolecular Interactions

Abstract

Green nanotechnology seeks eco-friendly solutions, capable of generating efficient nanotechnological protocols with low or no environmental impact. These nanosystems are marked out by intermolecular and supramolecular interactions capable of stabilizing the nanostructures and making nanotechnology effective. Many synthesis methodologies are being developed that involve a variety of biological sources. Among them, it can highlight biosynthesis using plant extracts. They are simple, cheap syntheses and have a fast reaction and low energy consumption. The dispersive vegetable medium is very complex due to its biomolecules. Extraction protocols must be established in order to isolate molecules efficient in colloidal stabilization. However, a lot has to be understood about these systems so that the present interactions have reproducible behavior worldwide.

Environmental Implications Associated with the Development of Nanotechnology: From Synthesis to Disposal

“…Another essential factor to be considered is that more eco-friendly conditions of pH, temperature, and pressure are adopted during green synthesis and the establishment of protocols with reactions that generate few or no by-products. Thus, the synthesis needs to be sustainable throughout the process including the disposal [ 29 , 30 , 31 , 32 ].…”

“…As a result, an important reduction of waste, cost, and environmental impact. It has also been reported that green synthesis using vegetable extracts or oils tends to be simple and fast, requiring fewer steps and hence minimizing the possibility of exposure [ 31 ]. Safety and control measures also need to be taken during handling to prevent accidental NM emissions.…”
