A multiplex microarray lateral flow immunoassay device for simultaneous determination of five mycotoxins in rice.

Co-occurrence of multiple mycotoxins is a growing global food safety concern due to their harmful effects on humans and animals. This study developed an eco-friendly sample preparation method and an innovative multiplex microarray-based lateral flow immunoassay, using a novel portable reader for on-site simultaneous determination of five regulated mycotoxins-aflatoxin B, T-2 toxin, zearalenone, deoxynivalenol, and fumonisin B in rice. The eco-friendly and ultrafast extraction procedure utilizes a bio-based solvent.

Development of peptide nucleic acid-based bead array technology for Bacillus cereus detection.

Numerous novel methods to detect foodborne pathogens have been extensively developed to ensure food safety. Among the important foodborne bacteria, Bacillus cereus was identified as a pathogen of concern that causes various food illnesses, leading to interest in developing effective detection methods for this pathogen. Although a standard method based on culturing and biochemical confirmative test is available, it is time- and labor-intensive.
