Special Issue Information

Dear Colleagues,

This Special Issue invites contributions to the current advances in the development and application of analytical methods for biomedical analysis aimed toward biological fluids or bodily fluids. This liquid class of specimens includes any liquids that can be found within the human body, such as urine, blood, or saliva. Bodily fluids are often extraordinarily complex in nature and mainly consist of salts, proteins, metabolites, and lipids, but they also contain other biomolecules carrying important information about the patient. Separation of these biomolecules prior to any analysis remains one of the most crucial components in today’s biomedical analysis and affects the downstream assay performance used to assess at what levels these molecules are present. Separation of these molecules can be performed at different levels to achieve a reduced complexity, ranging from upfront enrichment using nanoparticles or antibodies to alternative ion-sampling strategies when analyzing the sample using methods such as LC-MS/MS.

The target of this Special Issue is to present state-of-the-art separation methods applied to biological fluids, which enable sensitive detection or robust quantification suitable for clinical applications.

With your rich expertise in the field of biochemical separation, we believe that your contribution to this Special Issue will be of great importance to the scientific community.

Dr. Fredrik Edfors

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. Separations 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 2600 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.

Adenosine is a purine ribonucleoside with important roles in various physiological processes. A number of studies have indicated the importance of adenosine in cardiovascular diseases including syncope; however, the accurate determination of adenosine in human blood is challenging due to the molecule’s instability. In the present study, we report a simple method for the pre-treatment of blood samples and the development of a fast and efficient hydrophilic interaction chromatographic tandem mass spectrometry method for the analysis of adenosine in patient blood. During collection, samples were mixed directly with a solvent mixture containing 95% acetonitrile and 10 mM ammonium formate in a Vacutainer tube, resulting in successful prevention of adenosine metabolic processes and direct blood sample deproteinization. The method was validated according to bioanalytical industry guidelines and found to be accurate, repeatable, specific and sensitive with LLOQ 0.005 μg/mL, thus allowing its application in the analysis of real clinical samples.
