Special Issue Information

Dear Colleagues,

The highly efficient separation of chemical and biological species is vital in various fields, including, but not limited to, the analysis of biological, environmental, food, forensic, petrochemical, and pharmaceutical samples. There has been a rapid increase in the number of publications employing high-performance liquid chromatography, gas chromatography, and capillary electrophoresis to separate and detect a wide range of chemical and biological molecules. In addition, a series of techniques, such as solid-phase extraction (SPE), dispersive solid-phase extraction (DSPE), dispersive solid-phase microextraction (DSPME), solid-phase microextraction (SPME), microwave-assisted extraction (MAE), liquid-liquid extraction (LLE), and dispersive liquid-liquid microextraction (DLLME), have been used for sample preparation prior to the separation.

This Special Issue of Processes, entitled “Recent Advances in High Efficient Separation Methods for the Analysis of Chemical and Biological Samples", aims to publish high-quality research pertaining to the development of efficient sample preparation and high-resolution separation methods. Reviews as well as original research articles related to the sample preparation and separation of challenging samples are welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Determination of oxyanions is of paramount importance because of the essential role they play in metabolic processes involved in various aquatic environmental problems. In this investigation, a novel chemical sensor array has been developed by using gold nanoparticles modified with different chain lengths of aminothiols (AET-AuNPs) as sensing elements. The proposed sensor array provides a fingerprint-like response pattern originating from cross-reactive binding events and capable of targeting various anions, including the herbicide glyphosate. In addition, chemometric techniques, linear discrimination analysis (LDA) and the support vector machine (SVM) algorithm were employed for analyte classification and regression/prediction. The obtained sensor array demonstrates a remarkable ability to determine multiple oxyanions in both qualitative and quantitative analysis. The described methodology could be used as a simple, sensitive and fast routine analysis for oxyanions in both laboratory and field settings. Full article
