gmo-detection
GMO detection refers to analytical methods used to identify genetically modified organisms by detecting the presence of introduced DNA sequences, proteins, or other molecular markers that distinguish them from non-modified counterparts. In plant science, these techniques are essential for ensuring regulatory compliance, maintaining the integrity of non-GMO supply chains, and supporting biodiversity research by accurately characterizing plant material. Methods such as PCR-based assays, immunoassays, and next-generation sequencing enable researchers and regulators to verify the genetic composition of crop varieties and wild plant populations.

Scientists developed a new lab test called BeadPlex2 that can simultaneously detect multiple genetic modifications in crops with high accuracy, using CRISPR gene-targeting technology combined with light-scattering nanoparticles attached to magnetic beads.
Five distinct types of magnetic bead sensors (MagGERTs) were created, each encoding a unique Raman spectral signature to enable simultaneous multiplex detection of GM events
The system uses CRISPR/dCas9 (a DNA-binding version of CRISPR that does not cut DNA) for highly precise target recognition, reducing false positives compared to traditional methods
The BeadPlex2 platform was validated across diverse genetically modified crop events, demonstrating broad applicability for GM crop identification
