“…CNTs can detect strong charge transfer interaction in the host-guest binding of supramolecules and cause a change in their conductance, result in a more sensitive sensor (Zhu & Fang 2014). Several previous studies such as Gaichore and Srivastava (2012), Mermer et al (2012) and Wang et al (2012), demonstrated that the developed sensors have synergistic effect after combined the calixarene and CNTs together, lead to the production of better result in the guest detection. Besides the addition of CNTs to enhance the sensing property of calixarene, other approach included the addition of conducting polymer (Gokoglan 2015;Vigalok & Swager 2002).…”

In this study, we investigated the conductivity enhancement of calix [8]arene-multi-walled CNTs (MWCNTs) thin film. Two types of calix [8]arenes were used, which were 5,11,17,23,29,35,41,47-p-tert-butyl-49,50,51,52,53,54,55,56-oktakis[(carboxy)-pentoxy] -calix[8]arene (C[8]1) and 49,50,51,52,53,54,55,56 -octahydroxycalix[8]arene (C[8] 5,11,17,23,29,35,41,47-p-tert-butil-49,50,51,52,53,54,55,56-oktakis 49,50,51,52,53,54,55,56-oktahidroksikaliks[8] Dalam kajian ini, kami mengkaji tentang peningkatan kekonduksian lapisan nipis kaliks[8]arena-nanotiub karbon multidinding (MWCNTs). Dua jenis kaliksarena digunakan, iaitu [(karboksi)-pentoksi] -kaliks[8]arene (C[8]1) dan

“…Among other reported methods for β-adrenergic agonists detection [11][12][13][14][15][16][17] , the immunoassay has been paid great attention due to its easy-operation protocols, comparable simple pretreat of the samples and high specificity. Therefore, the enzyme-linked immunosorbent assay (ELISA) and the immunochromatographic lateral flow strip (LFS) have been well commercialized as the kit for rapid and sensitive detection of β-adrenergic agonists [18][19][20][21][22] .…”

Clenbuterol (CL), salbutamol (SAL) and ractopamine (RAC) are the three common β-adrenergic agonists which are the main hazards in food safety and affect human health through the food chain. A convenient and efficient method is urgently required to perform on-site detection of multiple β-adrenergic agonists to avoid frequent poisoning incidents. In this paper, a 2-directional lateral flow strip technique (2-directional LFS) is developed for rapid and simultaneous detection of CL, SAL and RAC with single sampling. Compared to conventional lateral flow strip, this 2-directional LFS technique can realize simultaneous detection of three or more target analytes without any change of intrinsic simplicity of LFS. Furthermore, this 2-directional LFS can effectively avoid the potential intrinsic cross-reactivity among the reagents to analogues. Under the optimized conditions, CL, SAL and RAC were all successfully determined with satisfied results in both buffer and urine samples with the detection limit as low as 0.5 ng/mL. This 2-directional-LFS technique can revolutionize the commercial single-analyte LFS products and can effectively widen the applications of the classic LFS in various fields.

“…[3][4][5][6][7][8][9][10] Electrochemical sensors have been proven as an inexpensive, simple and versatile analytical tool with remarkable detection sensitivity, reproducibility, ease of miniaturization and specic selectivity of target molecules. [11][12][13][14][15][16][17][18] They have found a vast range of important applications in the elds of clinical, industrial, environmental and agricultural analyses. [19][20][21] In addition the modication of electrode surface to act as a sensor is a widely used electroanalytical strategy useful for many sensing applications requiring highly compatible and properly functionalized surfaces to anchor the recognition material.…”
