“…[1][2][3][4][5][6] Recently, graphene-nanocomposite magnetic nanoparticles have been developed as an alternative to the application of carbon-based nanomaterials in the environment. [7][8][9][10][11][12] Typically, magnetic nanoparticles are dispersed into a sample solution to adsorb target compounds through the interaction of graphene with analytes. e nanoparticles are then collected rapidly and easily with an external magnetic eld, and the adsorbed analytes are subsequently eluted with solvents for the identi cation of analytes of interest.…”

In this article, we describe the application of surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) with the use of amine functionalized graphene-coated cobalt nanoparticles (CoC-NH 2 nanoparticles) to analyse aromatic hydrophobic compounds that are known environmental contaminants, including polycyclic aromatic hydrocarbons (PAHs) and pentachlorophenol (PCP). Our results demonstrated that SALDI-MS can detect PCP, anthracene, and pyrene in water. In particular, the CoC-NH 2 nanoparticles proved to be an e cient means of capturing PCP in water because of the high adsorption capacity of the nanoparticles for PCP, which resulted in a detectability of 100 ppt. Furthermore, the CoC-NH 2 nanoparticles also functioned as an adsorbent for solid-phase extraction of per uorooctane sulfonate (PFOS) from human serum, displaying good performance with a detectability of 10 ppb by SALDI-MS.

A B S T R A C TSample preparation is a crucial bottleneck in the whole analytical process. Solid-phase sorbents (SPSs) have aroused increasing interest in research on sample preparation, as they have key roles in obtaining high clean-up and enrichment efficiency in the analysis of trace targets present in complex matrices. The objective of this review is to provide a broad overview of the recent advances and applications of SPSs in sample preparation prior to chromatographic analysis, during the period 2008-13. We include SPSs, such as molecularly-imprinted polymers, carbon nanomaterials, metallic nanoparticles and metal organic frameworks, focusing on solid-phase extraction, solid-phase microextraction, matrix solid-phase dispersion and stir-bar sorptive extraction of typical pollutants in environmental, biological, food and pharmaceutical samples. We propose remaining challenges and future perspectives to improve development of new SPSs and to apply them further.

“…GC-MS can also be used in airport security to detect substances in luggage or on human beings. Additionally, it can identify trace elements in materials that were previously thought to have disintegrated [28] beyond identification. GC-MS has been widely heralded as a "gold standard" for forensic substance identification because it is used to perform a specific test.…”

One of the major challenges facing the pharmaceutical industry today is finding new ways to increase productivity, decrease costs whilst still ultimately developing new therapies that enhance human health. Both Biotechniques & Bioprocess engineering are integrated for bulk drug manufacturing of biopharmaceutical products to outcome the above problem. Different biotechnological processes are used in industries for large scale production of biological products for optimization of yield and the quality of end product. Various recent developments in biotechniques and its collaborated work with bioprocess engineering helps to maintain the quality in manufacturing process. However in this review article, we systemically describe all the techniques and different bioprocess used for manufacturing of drugs. To the author's knowledge this review represents the most exhaust description of different biotechniques, different bioprocess, process development and design criteria in bioprocess.
