Direct mass spectrometry (MS) is an exciting strategy in bioanalysis, enabling rapid decision-making different scenarios. Its application usually hindered by matrix effects and the typically low concentration of target compounds biofluids. In this sense, combining a previous sample preparation step minimizes or removes these shortcomings. This article describes sorptive tape-spray tandem (STS-MS/MS) based on mixed-mode particles as to combine MS analysis single device. The technique uses...
Access to clean water, a Sustainable Development Goal, can only be accomplished worldwide using affordable technologies. In the analytical chemistry realm, developing cheap devices capable of on-site extraction results in helpful tool. This article presents new device based on open-source technologies for isoflavones from environmental waters as proof concept. The is wholly operated by an Arduino microcontroller that also integrates sensors (temperature and conductivity) provide information....
This article describes the synthesis of mixed-mode cationic exchange (MCX) tapes as sorptive phases in bioanalysis, and it faces determination methadone tramadol saliva model analytical problem. The are synthesized using aluminum foil substrate, which is subsequently covered with double-sided adhesive tape where MCX particles (ca. 1.4 ± 0.2 mg) finally adhere. allow extraction analytes at physiological pH, both drugs positively charged, minimizing potential co-extraction endogenous matrix...
The spatial heterogeneity of environmental systems makes sampling at multiple locations crucial to provide complete and representative information. on-site application an extraction technique simplifies the logistics, increasing sample integrity during transportation storage.

Magnetite nanoparticles (Fe3O4) functionalized with graphene oxide (GO) have been synthesized through a silanization process of the magnetic tetraethyl orthosilicate and (3-aminopropyl)triethoxysilane further coupling GO. The nanomaterials characterized by several techniques, such as transmission electron microscopy (TEM), infrared Raman spectroscopy, which enabled evaluation different steps functionalization process. hybrid nanomaterial has employed for extraction five benzophenones...
Abstract An on-site extraction device is presented consisting of scotch tape modified with concentric domains micrometric hydrophilic-lipophilic balance (HLB) particles surrounded by a ring nanometric magnetic ones. On the one hand, HLB microparticles are readily available at surface tape, exposed to interact target analytes, being responsible for capacity sorptive phase. other presence nanoparticles enables attachment onto metallic screw via magnet, which then coupled wireless drill,...
Polymeric nanocomposites have been extensively used as sorbents to extract pollutants from environmental waters before their final instrumental analysis. These materials are highly versatile and can be adapted a given analytical problem by selecting the polymer/nanomaterial combination adequately. The adaptability of is strengthened easy preparation in laboratory different formats (particles, membranes, monoliths, or fibers) which they obtained. This article delivers general overview...
Environmental compartments are characterized by their large size and the heterogeneous distribution of target analytes. Onsite extraction procedures especially useful in this scenario, allowing development ambitious sampling campaigns (including a larger number locations periods). This article outlines relevance techniques, including exhaustive non-exhaustive ones, onsite strategies. However, only stirred units discussed described detail. The discussion analytical performance (for example,...
