Surface plasmon resonance immunosensor for the detection of Salmonella typhimurium

Electroless-plated gold films for sensitive surface plasmon resonance detection of white spot syndrome virus

“…4c. The fact that the gold clusters or grains become "smoother" suggested that a closely packed assembly had been formed because of the interaction of these molecules with the AFM tip and the van der Waals forces among the alkyl chains (Oh et al, 2004). With the covalent immobilization of A1 on the as-prepared surface, small spots appeared and uniformly distributed in the AFM image (Fig.…”

Immunoimmobilization of Living Salmonella for Fundamental Studies and Biosensor Applications

“…This approach has been used to detect Salmonella (Table 1) (Mantzila et al 2008;Oh et al 2004) and other bacterial pathogens Skottrup et al 2008;Velusamy et al 2010a). Efficient capturing is always desired for bacterial detection, since it will facilitate converting captured pathogens into a detectable signal and, most importantly, a higher capture efficiency will result in a higher sensitivity (lower detection limit).…”

The application of neoglycopeptides in the development of sensitive surface plasmon resonance-based biosensors

“…Nowadays, biosensors are widely applied for the detection, identification, and characterization of biological material, which is of great importance in industrial (Castillo et al, 2004), medical (Hsieh et al, 2004;Dillon et al, 2005;Jiang et al, 2005), food (Gustavsson et al, 2002;Haasnoot et al, 2002;Indyk and Filonzi, 2005;Muller-Renaud et al, 2005), and environmental (Castillo et al, 2004) analysis. Surface plasmon resonance-based biosensors are currently widely used to monitor these interactions (Chou et al, 2004;Oh et al, 2004;Choi et al, 2005). Although analytes can be detected by a wide range of immobilized ligands, such as antibodies (Soh et al, 2003;Liu et al, 2004;Choi et al, 2005;Muller-Renaud et al, 2005), enzymes, and carbohydrate-binding proteins (CBPs) (Hsieh et al, 2004), the development of carbohydrate-based biosensors has recently received increased attention because of the importance of carbohydrate-protein interactions in life.…”
