Simple and suitable immunosensor for β-lactam antibiotics analysis in real matrixes: Milk, serum, urine
2015, Journal of Pharmaceutical and Biomedical AnalysisCitation Excerpt :Conversely, our method only needs cheap and widely available apparatus (a simple potentiostat, an H2O2 electrode and an easily purchasable and relatively cheap antibody). As far as the comparison with other published sensor methods is concerned, a short analytical comparison is given in Table 11, considering of course above all the immunological type of sensor method [26,36–38], although extending it synthetically also to the enzymatic methods [68–73] with different types of detection and to the selective membrane potentiometric methods [74,75]. It is immediately apparent that the latter two types of sensors generally have inadequate LODs and at the same time a linearity range that is generally not as wide as in the case of our new immunosensor but also in the case of other immunological methods, only one [37] practically presents an LOD value lower than that of our method.
New immunosensor for β-lactam antibiotics determination in river waste waters
2014, Sensors and Actuators, B: ChemicalCitation Excerpt :These values are still more than acceptable, however, for the development of any kind of immunological method. A comparison of the main analytical data referring to penicillin G analysis, obtained using both the present immunosensor and ion selective electrodes (ISEs) investigated in previous research by the present and other authors [29,30] and by enzyme sensors [31–44] or immuno-devices developed by other authors [45–53], is shown in Table 7. The lower detection limit is 10−10 M for the present immunosensor, about 10−4 or 10−5 M usually for most of the penicillinase enzymatic sensors and about 10−4 M for most of the ISEs responsive to penicillin G.
