Encoded Microspheres in Multiplex Detection of Mycotoxins and Other Analytes
This paper provides a systematic review of encoded microsphere suspension array technology and its application in multiplex detection of mycotoxins. Mycotoxins are diverse and frequently coexist, leading to synergistic toxic effects and challenges in risk assessment. Current methods face bottlenecks like target loss, matrix interference, and reliance on large instruments. Encoded microsphere technology, combined with efficient signal amplification, offers a highly sensitive and high-throughput platform. The review covers encoding strategies (physical, optical, multi-dimensional), new materials (AIE materials, fluorescent proteins), matrix materials, preparation methods (green, biocompatible), signal amplification (nucleic acid, enzyme catalysis, nanomaterials), and integration with magnetic separation and portable devices. Future trends include AI, 3D printing, and smart algorithms for intelligent on-site detection, providing theoretical and technical support for related fields.

Executive Impact Assessment
The development of encoded microsphere suspension array technology significantly advances food safety and biomedical diagnostics. By addressing the limitations of traditional methods—such as target loss, matrix interference, and the need for large-scale instruments—this innovation offers a robust solution for the simultaneous, highly sensitive, and high-throughput detection of multiple analytes, including diverse mycotoxins. This leads to faster, more accurate risk assessments and improved food safety measures, directly impacting consumer health and regulatory compliance. The integration of advanced encoding strategies, green fabrication methods, and powerful signal amplification techniques promises a new generation of portable and intelligent detection systems, making high-precision analysis accessible even in resource-limited settings. This not only enhances the efficiency of current testing protocols but also opens up new avenues for personalized medicine and environmental monitoring, solidifying its role as a transformative technology in analytical science.
Overall Business Impact
For enterprises, this technology translates into significant operational efficiencies and strategic advantages. Reduced detection times and increased throughput lead to lower labor costs and quicker decision-making in quality control. The enhanced sensitivity minimizes false negatives, preventing costly recalls and ensuring brand reputation. The ability for multiplex detection with a single sample streamlines workflows, reducing reagent consumption and waste. Furthermore, the push towards portable, AI-driven platforms enables on-site testing, which can drastically cut down on external lab expenses and logistics, accelerating product release and market response. Early adoption of such advanced bio-detection systems provides a competitive edge, fostering innovation in R&D and ensuring compliance with evolving food safety standards globally. This investment in advanced analytics is an investment in future growth and resilience.

Smartphone-Based Mycotoxin Detection
Ji et al. used stop-flow lithography to produce shape-encoded hydrogel microspheres for aflatoxin B1 and ochratoxin A detection. A smartphone camera captured images, with an integrated image algorithm completing shape recognition and digital analysis of fluorescent regions within 10 seconds. This enabled simultaneous detection with high throughput and practicality, achieving detection ranges of 0.1-200 ng/mL for aflatoxin B1 and 0.1–500 ng/mL for ochratoxin A, and spiked corn recovery rates of 81.5–121%.
