There may be risk of multiple veterinary drug residues in one food sample; thus, a key challenge for the simultaneous detection of multiple targets was raised in food safety anal. In this study, a multi-dot membrane immunochip sensor (MIS) based on Braille-like code was proposed for the sensitive, specific, and simultaneous detection of four veterinary drugs: sulfamethazine (SMZ), amantadine (AMD), danfloxacin (DAN), and tylosin (TYL). The 16 types of residual situations for four veterinary drugs can be qual. and quant. analyzed through the Braille-like code and signal intensity of dots. In addition, an Android application was exploited to intelligently identify the Braille-like code pattern; thus, the residue situations of the corresponding veterinary drugs can be automatically output by a smartphone. The cutoff values were 25 ng/mL for the four veterinary drugs by the naked eye. The limits of detection for SMZ, AMD, DAN, and TYL were calculated as 0.22, 0.058, 0.29, and 0.14 ng/mL, resp. To verify the performance of this multi-dot MIS, spiked chicken samples with different concentrations were tested, and the results verified the accuracy and precision of this method. The average spiked recoveries were 79.2-116.7%, and the coefficient of variation was 1.6-10.5%. Flexible, versatile and intelligent discriminant methods give this multi-dot MIS great potential to rapidly recognize complex situations in the field of simultaneous detection of analytes. In the experiment, the researchers used many compounds, for example, 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3Recommanded Product: 1220-83-3).
4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3) belongs to pyrimidine derivatives. The pyrimidine nitrogenous bases are derived from the organic compound pyrimidine through the addition of various functional groups. Drugs having the pyrimidine motif have manifested to exhibit gratifying biological activity like anticancer, antiviral, anti-inflammatory, antibacterial, and antihypertensive activities.Recommanded Product: 1220-83-3
