Professor Yueyun Li's research lab specializes in the design and application of advanced nanomaterials for environmental remediation and biomedical sensing. The lab focuses on developing functional nanocomposites—such as nano-graphite/Fe3O4 composites—for efficient removal of pollutants like dyes from water, while also pioneering novel electrochemiluminescence biosensors using AIE-active luminophores for sensitive biomarker detection. Their work integrates materials synthesis, surface engineering, and analytical chemistry to address challenges in environmental sustainability and disease diagnostics. The lab emphasizes innovative strategies such as liposome-encapsulated emitters and peptide-based recognition to enhance sensitivity and selectivity in biosensing platforms.

Nano-graphite/Fe3O4 composite (NG/FC) synthesized through deposition–precipitation method, was developed for the removal of methyl violet (MV) from aqueous solution. The parameters including pH, temperature and shaking time on MV removal efficiency were extensively investigated. The adsorption of MV increased smoothly in the pH range of 2.0–4.0, then remained at a higher level for the pH range of 4.0–10.0, but increased sharply at pH > 10.0, which demonstrated that the adsorption was affected st
In this work, a sensitive signal-on electrochemiluminescence biosensor using liposome-encapsuled 1,1,2,2-tetra(4-carboxylphenyl)ethylene (TPE) as a promising aggregation-induced electrochemiluminescence (AIECL) emitter for detection of biomarkers was developed. Aggregation-induced enhancement occurs internally through the spatial confinement effect and intramolecular self-encapsulation of encapsulating TPE and triethylamine (TEA) molecules in liposome cavities.
