Sample preparation is a paramount step of the analytical process that has undergone significant improvements within the framework of green chemistry. The present review reports on cutting-edge advances toward greener analytical methods involving sample preparation. Remarkable contributions published in the last two years on the implementation of greener solvents and adsorbents in sample preparation approaches, integration of unitary steps, miniaturization, and automation are discussed. Concluding remarks and additional considerations for further improvements are also addressed.
