Lab of Biochemistry & Functional Materials


Research Interests

Our group is mainly interested in the research field of marine biomaterials & living resources comprehensive utilization.

Marine biomaterials:

Functional materials based on biological macromolecules: extraction, screening, modifications and characterizations;

Design of a series of structure and morphology controllable functional materials: nanoparticles, nanomembranes, nanocapsules, nanotubes, nanofiber, microcapsules, microspheres and phase-change materials.

Biological activities investigation of marine biomaterials: anticoagulant, antibacterial activity, antifungal activity, moisture retention, hygroscopicity, promote healing, act.

Marine living resources complex utilization:

Bioactive constituents come from marine organisms and aquatic product processing offal: isolation, preparation, screening, modification and characterization;

Application of marine living resource in water purification, food preservation and heavy metal ions adsorption.
