On October 14, 2025, Researcher Ma Guangzhong from Jilin University was invited to visit the Institute of New Concept Sensors and Molecular Materials and presented a report titled “Label-Free Chemical Microscopy”.

Ma’s presentation focused on label-free imaging techniques—a rapidly evolving field in chemical reaction visualization. Beginning with fundamental principles, he introduced label-free imaging technologies based on scattering, reflection, and interference, and outlined his group’s contributions in this domain, including advancements in chemical/electrochemical imaging and biosensing.

The session was hosted by Prof. Peng Haonan, with over 40 faculty members and students from the institute in attendance.
