“…The detection limit of this assay was 4.52 ng ml À1 CAP, defined as the CAP concentration corresponding to the mean Au signal intensity of a zero standard (n ¼ 12) minus three standard deviations. 19 The detection limit of CAP obtained by our method is slightly improved from what has been reported earlier by the conventional ELISA (optical density based on indirect competitive immunoassay) 21 and immunochromatographic assay (using AuNPs as a probe detection), 22 which showed a detection limit of 10 ng ml À1 . The advantages of ICP-MS detection for routine performance of immunoassays include increased sensitivity, minimal interference from complex matrices and high throughput.…”

This paper describes the feasibility for trace analysis of chloramphenicol using a novel immunoassay by coupling competitive measurement of chloramphenicol (CAP) to ICP-MS by the use of CAP labeled with AuNPs. Polyclonal rabbit anti-mouse immunoglobulins (anti-mouse IgG) were pre-coated on the 96-well polystyrene microplate solid support to allow the retention of mouse monoclonal to chloramphenicol (MAb-anti-CAP) antibody-CAP on the plates. Samples containing CAP as an antigen premixed with CAP-BSA protein labeled with AuNPs as an immunogenic tag were added to the MAb-anti-CAP bound solid support, physically separated from non-reacting molecules. The AuNPs were measured by ICP-MS to indirectly determine the CAP concentration in the samples. For 10 nm AuNPs, the optimal condition for CAP-BSA protein conjugation was pH 9.5 and 120 mg l À1 of CAP-BSA protein. The detection limit, linearity range, and precision (intra-assay, inter-assay) were 4.52 ng ml À1 , 0-20 ng ml À1 , and less than 20%, respectively.

SummaryHerein we present a survey of the literature covering the development of molecular imprinting science and technology over the years 2004 to 2011. In total, 3779 references to the original papers, reviews, edited volumes and monographs from this period are included, along with recently identified uncited materials from prior to 2004 which were omitted in the first instalment of this series covering the years 1930 to 2003. 1 In the presentation of the assembled references, a section presenting reviews and monographs covering the area is followed by sections describing fundamental aspects of molecular imprinting including the development of novel polymer formats. Thereafter, literature describing efforts to apply these polymeric materials to a range of application areas is presented. Current trends and areas of rapid development are discussed.2

Cd(ii) ion was used as template ion, and N,N'-pyridine-2,6-di(2-methacrylamide) was used as the functional monomer. The experimental conditions for the synthesis of Cd(ii) ion-imprinted composite membranes (Cd(ii)-IICMs) were optimized by the surface-imprinting method, and 25 Cd(ii)-IICM1–25 and their corresponding non-imprinted composite membranes (NICM1–25) were prepared. Then, the structures of the optimal membranes Cd(ii)-IICM17 and NICM17 were characterized by scanning electron microscopy, Brunner–Emmett–Teller, thermogravimetric analysis, contact angle analysis, and the effects of different adsorption conditions were studied. The adsorption behavior was analyzed by isothermal adsorption models and kinetic models. The permeation selectivity of Cd(ii)-IICM17 towards Cd(ii) ions was studied. Results of the experiment indicate that Cd(ii)-IICM17 had excellent adsorption properties for Cd(ii) ions with an imprinting factor of 2.15. The adsorption of Cd(ii) ions in solution by Cd(ii)-IICM17 and NICM17 was in accordance with the Freundlich isothermal adsorption model and the pseudo-second-order kinetic model. In addition, in the presence of the competing ions Co(ii), Ni(ii), and Cu(ii), Cd(ii)-IICM17 showed good permeation selectivity for Cd(ii) ions, and the permeation process followed a facilitated permeation mass-transfer mechanism. In summary, the Cd(ii)-IICM17 prepared in this study has good application prospects for the separation and removal of Cd(ii) ions from wastewater.
