biosensor
Biosensors are analytical devices that combine a biological recognition element—such as an enzyme, antibody, or nucleic acid—with a physicochemical detector to identify and quantify specific chemical substances. In plant science, biosensors enable real-time monitoring of plant metabolites, hormones, and signaling molecules both in vitro and within living plant tissues. This technology accelerates research into plant stress responses, nutrient uptake, and secondary metabolism by providing precise, rapid measurements that traditional analytical methods cannot match.

Scientists developed three portable, fast-testing kits using CRISPR gene-editing technology to detect plant diseases in the field — no lab required. These tools can identify pathogens in under 45 minutes with accuracy rivaling standard lab tests.
Detection limits of 1–100 copies per microliter were achieved, matching conventional PCR lab tests in sensitivity.
All three assay formats delivered results within 20–45 minutes, far faster than standard laboratory diagnostics.
Three distinct platforms were validated: a lateral-flow strip test for DNA pathogens, an RNA virus assay, and an amplification-free electrochemical biosensor for portable lab settings.
