Stimuli-responsive materials, frequently designated as “smart/intelligent materials”, can modify their structure or properties by either a biological, physical, or chemical stimulus which, if properly controlled, could be used for specific applications. Such materials have been studied and exploited in several fields, like electronics, photonics, controlled drugs administration, imaging and medical diagnosis, among others, as well as in Analytical Chemistry where they have been used as chromatographic stationary phases, as part of sensors and for extraction purposes. This review article pretends to provide an overview of the most recent applications of these materials (mostly polymeric materials) in sample preparation for extraction purposes, as well as to provide a general vision of the current state-of-the-art of this field, their potential use and future applications.

刺激响应材料，通常被称为“智能/智能材料”，可以通过生物，物理或化学刺激来改变其结构或特性，如果适当控制，可以用于特定应用。这类材料已在电子，光子学，药物控制，成像和医学诊断等多个领域进行了研究和开发，在分析化学中已用作色谱固定相，用作传感器的一部分和用于提取目的。这篇评论文章假装概述了这些材料（主要是聚合物材料）在用于提取目的的样品制备中的最新应用，并提供了对该领域当前最新技术的总体了解，
