Selective capturing and detection of Salmonella typhi on polycarbonate membrane using bioconjugated quantum dots

Development of a propidium monoazide treatment combined with loop‐mediated isothermal amplification (PMA‐LAMP) assay for rapid detection of viable Listeria monocytogenes

“…The PMA-LAMP assay was applied to spiked raw food samples and milk powder to demonstrate applicability for field testing. Molecular biology techniques such as , quantum dots detection (Jackeray et al, 2011), LAMP assay (Tang et al, 2011;Wang et al, 2012) and DNA microarray analysis (Wang et al, 2010) are methods that help shorten the detection turn-around time that provides benefits for the control and prevention of pathogenic contamination. However, most of the DNA-based detection methods cannot distinguish DNA from viable and dead cells.…”

Assay of bacteriorhodopsin stability on polycarbonate surface by using of FTIR-ATR: a model of disk-based bioassays

“…For immobilization of BR on the polycarbonate surface, the modification should be done. So far different modifications have been done (Abenojar et al 2009;Asad Ali et al 2010;Baumann et al 2013;Carosio et al 2013;Dehaye et al 2003;Gao et al 2013;Goyal et al 2012;Heymans 1997;Iwata et al 2003;Jackeray et al 2011;Jain et al 2012;Jang et al 2014a, b;Keil et al 1998;Khan et al 2006;Kim and Masuoka 2009;Kumar et al 2003Kumar et al , 2006Kumar et al , 2012Lub et al 1988;Motaung et al 2013;Resta et al 2013;Rodríguez et al 2002;Saarikoski et al 2009;Singh et al 2007;Srivastava et al 2002;Sun et al 2003;van der Wel et al 1993;Verkuijlen et al 2014;Wang et al 2000;Zajíčková et al 2001;Zhou and Osby 2010). In the present study we try to immobilize bacteriorhodopsin on polycarbonate surface by modifying of polycarbonate functional groups in two ways.…”

Semiconductor Nanomaterials-Based Fluorescence Spectroscopic and Matrix-Assisted Laser Desorption/Ionization (MALDI) Mass Spectrometric Approaches to Proteome Analysis

“…The BSA-coated QDs strongly influenced the physical properties of membranes and decreased the cell membrane fluidity and the cell surface of E. coli . Singh’s group applied TGA-capped CdSe/ZnS core/shell QDs to detect Salmonella typhi [75] in which the carbodiimide chemistry was utilized to conjugate S. typhi through carboxy terminated TGA capped QDs. This mechanism was based on the sandwich fluoroimmuno sensing between antibody immobilized membrane and bioconjugated QDs.…”
