The second part of the review shifts attention to novel modern materials applied to dSPE as sorbents, that are often designed specifically for the extraction of a particular analyte. This part will focus on advances in materials such a molecularly imprinted polymers (MIP), metallic organic frameworks (MOF), layered double hydroxides (LDH) or magnetic nanoparticles (MNP). As in the first part, studies chosen for this review will be listed in tables alongside their relevant validation parameters at the end of each chapter. Studiesfound to be particularly interesting due to high effectiveness, unusual operating procedure or scope, among other reasons, will be described in greater detail.

Solid phase extraction (SPE) is an analytical procedure developed with the purpose of separating a target analyte from a complex sample matrix prior to quantitative or qualitative determination. The purpose of such treatment is twofold: elimination of matrix constituents that could interfere with the detection process or even damage analytical equipment as well as enriching the analyte in the sample so that it is readily available for detection. Dispersive solid phase extraction (dSPE) is a relatively recent development of the standard SPE technique that is attracting growing attention due to its remarkable simplicity, short extraction time and low requirement for solvent expenditure, accompanied by high effectiveness and wide applicability. There is an enormous abundance of articles concerning advances in sample preparation and analysis published every year. The aim of this review is to bring to closer attention developments of materials with potential application as sorbents in dSPE technique through a thorough survey of recently conducted analytical studies focusing on methods utilizing novel, interesting nanomaterials in dSPE procedures and evaluation of their performance and suitability based on comparison of provided validation parameters with previously reported analytical procedures. The first part of this review focuses on widely known and utilized materials such as silica and carbon and their modifications, up to and including graphene and carbon nanotubes. Studies chosen for this review will be listed in tables alongside their relevant validation parameters at the end of each chapter. Applications found to be particularly interesting due to high effectiveness, unusual operating procedure or scope, among other reasons, will be described in greater detail.
