Rapid and sensitive detection of clomazone in potato and pumpkin samples using a gold nanoparticle-based lateral-flow strip

Development of immunochromatographic strips for the rapid detection of diquat in apples and strawberries

“…Both of these affect the ability of the antibody to bind to the antigen. 25,29,34 Fig. 2a shows that a lower IC 50 value was obtained at pH 6.5 when other conditions remained constant.…”

Gold nanoparticle-based lateral flow immunoassay for the rapid detection of flutriafol residues in food

“…As shown in Fig. 1A, the preparation of nitration products (FTF-1) was carried out as reported previously 23 with some modifications. Briefly, HNO 3 (1.5 mL, 16 mol L À1 ) and H 2 SO 4 (6 mL, 18 mol L À1 ) were mixed and added dropwise to FTF (1 g, 3.3 mmol) dissolved in anhydrous EtOH (20 mL) and stirred at À10 1C for 5 h. The reaction was then heated to 0 1C, and 100 mL of an ice water mixture was slowly added along with NH 3 ÁH 2 O to adjust the solution to alkaline pH (pH 9), and a yellow precipitate was formed.…”

Preparation of a broad-specific monoclonal antibody and development of an immunochromatographic assay for monitoring of anthranilic diamides in vegetables and fruits

“…A similar combination was also found to be the best in the previous studies. 39,40 The mouse which had the optimal antiserum titer and inhibitory effect against the four anthranilic diamides was sacrificed for mAb screening.…”
