Green nanomaterials in sample pre-treatment processes

Abstract

Extraction is an important step in sample pre-treatment processes for the efficient removal of an analyte of interest from a complex matrix. Removal of harmful pollutants from contaminated food, environmental, and biological samples is a crucial demand. Green extraction techniques have been developed as greener and more sustainable alternatives to traditional sample preparation methods. These techniques aim to improve the selectivity and sensitivity of analytical methods and simultaneously reducing the harmful side effects of conventional extraction techniques. Green nanomaterials have advanced extraction technologies due to their unique physicochemical features and facile surface functionalization. This chapter presents the synthesis of green nanomaterials and their use in analytical applications, with a special focus on their roles as sorbent materials. © 2024
