“…Although there are reports in the literature on the trace elements content in plants, we are still far from the point of knowing exactly the mechanisms of action and the formation of active constituents for ech medicinal plants. Major and Minor elements have very important functions and it is believed a key component of proteins such as haemoprotein and haemoglobin which play role in biochemical functions and essential enzyme system even in low doses (Erden & Kılıç, 2013). 1760.28 ± 12.39 Each value is the mean ± standard deviation of five determinations, Values bearing the same letter showed no significant difference (P < 0.05).…”

The aim of this study was to investigate the chemical composition of the best known plants biomarkers from the locality of Gafsa (Tunisia). Majority of investigated plants had high levels of phenolics and exhibited noteworthy antioxidant activity. The plants showing the highest antioxidant activities were P. angustifolia, T. garganica, G. alypum and L. multifida. P. angustifolia demonstrated by far the most potent antioxidant activity, as well as total phenolic and total flavonoids content. In flavonoid structure of the aerial parts of the related species, different amounts of rutin, myricetin, morin, quercetin and kaempferol together with ergosterol, stigma sterol and b-sitosterol as phytosterols, vitamin D, vitamin K, a-tocopherol and retinol as vitamins, and arabinose, fructose, glucose, sucrose and maltose as sugars were found. The mineral analysis was related to the existence of Ca, Na, K, Fe, Mn, Zn and Mg with different amounts in all of the nine tested species.

In recent time, several novel biosensors such as enzyme based, immunosensors, tissue-based, DNA biosensors, piezoelectric, and thermal biosensors have been explored with high sensitivity by many research groups. These biosensors exhibit many essential benefits, including operational simplicity, remarkable sensitivity, low-cost instrumentation, the potential of automation, inherent miniaturization. They have offered elegant paths for the detection of even trace amounts of analytical agents of biological significance existing from macromolecules (e.g., disease biomarkers and antigens) and small molecules (e.g., natural toxins and haptens) to cells, viruses, and bacteria. Many electrochemical techniques viz., amperometry and voltammetry, photoelectrochemistry, electrochemiluminescence, impedance, piezoelectricity, potentiometry, alternating current electrohydrodynamics, and field-effect transistor have been utilized in the development of immunoassays to attain high sensitivity for electrochemical signal transduction. Recent developments in biological methods and instrumentation after using fluorescence tag to various nanocarriers such as nanoparticles, nanowires, nanotubes, etc. have improved the sensitivity of biosensors. Utilization of nucleotides/aptamers, affibodies, molecule imprinted polymers, and peptide arrays offer great tools to prepare advanced biosensors. Merging of nanotechnology with biosensor systems enhanced the diagnostic capability. This review gives an outline of the advances in biosensors technology relating biomedical sciences.

: Screen printed carbon electrodes (SPCEs) with immobilized osmium-based hydrogel redox polymer, uricase and PEGDGE can be used to apply uric acid electrochemical detecting. The osmium redox complexes were synthesized by the coordinating pyridine group having different functional group at 4-position with osmium compounds. The synthesized poly-osmium hydrogel complexes are described as PAA-PVI- [Os(dCl-bpy)
