4] are finding increasingly widespread application in disease diagnosis and treatment, sustaining intense interest from both academia and industry. Against this backdrop, the 5
th Xihua Chemistry and Biomedicine Forum was successfully held at Xihua University (Chengdu) from July 12 to 15, 2025, infusing new vitality into academic exchanges and innovative progress in this domain.
The name "Xihua" carries a dual meaning: it not only clearly indicates that the venue is Xihua University but also contains the grand vision of "Western China" — based in western China and radiating to the whole country, it aims to help the chemical and biomedicine industries achieve leapfrog development by integrating scientific research forces from western China and the whole nation [

Chin. Chem. Lett. (CCL) has played a key role in the preparation of the Xihua Forum Series on Chemistry and Biomedicine (
Fig. 1), and its professional guidance and in-depth participation have provided important support for the successful holding of the forum.
