(31/07/2026) A co-modification strategy using KI and AgNO3 is developed to promote SERS papers with quenched florescence background and Raman enhancement. The quantitative detection from 10-7 to 10-5 M calibrated by the digital SERS analytical method with R2 up to 0.9964 opens up opportunities for low-cost paper-based SERS applications. Link
(26/06/2026) Congratulations to Dr. Yao Yao, for the Outstanding PhD Dissertation Award of BJUT.
(13/06/2026) A near-field differential scattering algorithm for high-fidelity and computationally efficient calculation of microsphere-assisted near-field nanofocusing is developed, establishing a scalable computational foundation for wavefront-engineered microsphere photolithography. Link
(26/05/2026) A monolayer-MoS2/ZnO-microtube (ML-MoS2/ZnO-MT) heterostructure is fabricated by capping ML-MoTe2 onto ZnO-MT via van der Waals forces. The deep-defect level and supported Fabry-Perot optical mode in the ZnO-MT provide an extra charge-transfer channel and promote multiple resonances, achieving ultrasensitive SERS detection with pronounced photodegradation performance for substrate reusability.

(17/04/2026) A protocol of fs-laser-induced periodic phase-transition of 2D-MoTe2 template, inducing AuNPs@1T’-MoTe2 nanograting, is developed. The labeled AuNPs@1T’-MoTe2 substrate conjugated with specialized immunoglobulin G demonstrates an unexpectedly high discrimination accuracy close to unity for serological diagnosis of rheumatoid arthritis by frequency-shift digital-SERS immunoassay.
