Various antibiotics widely used in agriculture, forestry and animal husbandry have become one of the main sources of w88 online casino betting contamination，In particular, the bioaccumulation effect of trace residues poses a more hidden threat to the human body。Therefore, it is particularly important to accurately and conveniently analyze trace antibiotic residues in complex w88 online casino betting samples。The researcher’s team uses original quartz rod nucleic acid modification technology to construct a solid-phase microextraction system，CombinedDNANano walker probe，Ultra-sensitive detection of chloramphenicol through dual amplification strategy。In addition，Through administration experiments on living animals，Explored the accumulation phenomenon of trace amounts of chloramphenicol in organisms。

In this research strategy，Constructing a solid-phase microextraction system using quartz rods with surface-modified nucleic acid sequencesAnalyteidentification capture, condensedEnrichedandDetectionIntroduction processCollectionforOne body，Greatly simplifies sample preprocessing operations；By quartz rod matrix andDNAThe interaction between the enzyme cycle shearing system will affect the effect of chloramphenicolDetection converted tofor specificnucleic acidSerialDetection，And perform the first nucleic acid sequence amplification；By the fourth generation sensor—DNAOperation of isothermal nucleic acid amplification on the surface of walker nanoparticles，w88 online casino betting was amplified for the second time。

In recent years，The team leverages related technologies，Published multiple relevant papers in top international publications in the w88 online casino betting field，such asw88 online casino betting Chem., 2024, 442, 138505；w88 online casino betting Chem., 2023, 416, 135856；Anal. Chem., 2022, 94, 10595-10600；w88 online casino betting Control, 2025, 168, 110871etc.，Solved the problem of highly sensitive detection of hazardous substances in w88 online casino betting。Relevant research received the National Natural Science Foundation of China、Jiangsu Provincial Natural Science Foundation、Support from Jiangsu University of Science and Technology’s “Deep Blue Talent Project” training object funding project。
