Immunochromatographic colloidal carbon-based assay for detection of methiocarb in surface water

Nanoparticle-based lateral flow biosensors

“…10), a factor which helps to obtain good parameters of sensitivity, working range and limit of detection. CNPs, as AuNPs, can be used for the detection of antigens (Lönnberg and Carlsson, 2001;Van Dam et al, 2004;Rayev and Shmagel, 2008), DNA chains (Kalogianni et al, 2011;Noguera et al, 2011) and molecules (Koets et al, 2006;Blažková et al, 2009Blažková et al, , 2010, allowing also the development of multidetection LFS (Noguera et al, 2011).…”

Development of an immunochromatographic assay based on carbon nanoparticles for the determination of the phytoregulator forchlorfenuron

“…Gold nanoparticles are often preferred (Seydack, 2005;Anfossi et al, 2011), but other materials such as colloidal carbon (Blažková et al, 2009(Blažková et al, , 2010(Blažková et al, , 2011Koets et al, 2006;Lönnberg et al, 2008;Noguera et al, 2011;OKeeffe et al, 2003), latex particles (Campbell et al, 2007) or quantum dots (Zou et al, 2010) and enzymes (Mirasoli et al, 2012) are also employed. In a survey performed by Gordon and Michel (2008) for sensitivities of labels that are used in lateral flow assays, carbon nanoparticles were ranked above gold and latex nanoparticles.…”

“…Even though ELISA certainly is one of the most widespread and popular kind of immunoassays, immunochromatographic assays are better suited for on-site rapid applications. The large number of scientific publications in the diagnostic (Andreo et al, 2006;Mens et al, 2008), medical (Lin et al, 2008;Omidfar et al, 2012;Yang et al, 2011), veterinary (Noguera et al, 2011), drug of abuse (Gandhi et al, 2009), environmental (Blažková et al, 2009;Kim et al, 2003;Zhou et al, 2010), and food safety areas (Anfossi et al, 2011;Aldus et al, 2003;Tang et al, 2009;Zhang et al, 2011;Zhou et al, 2009), well illustrates the prominent position that immunochromatographic methods have attained in the analytical field as portable point-ofcare devices in recent years (Posthuma-Trumpie et al, 2008).…”

Lateral Flow Immunoassay with the Signal Enhanced by Gold Nanoparticle Aggregates Based on Polyamidoamine Dendrimer

“…4,5 This is because it is rapid, portable, disposable, inexpensive, and friendly in the user format. The method is based on the capillary action of fluid through porous nitrocellulose strips and colored nanoparticles, such as colloidal gold, 6 colloidal carbon, 7 liposome, 8 quantum dots, 9 etc., used as a colorimetric detector.…”
