    The development of portable low-cost integrated optics-based biosensors for photonics-on-a-chip devices for real-time diagnosis are of great interest, offering significant advantages over current analytical methods. We report the fabrication and characterization of an optical sensor based on a Mach-Zehnder interferometer

    A dendrimer-like carbohydrate phytoglycogen (PG) extracted from corn was modified as a fluorescent nanocarrier via a simple method. Fluorescein was successfully linked to PG by covalent bonds through APTES as the bridge. NMR, XPS, UV, fluorescence and confocal microscopy validated

    Pollen's practically-indestructible shell structure has long inspired the biomimetic design of organic materials. However, there is limited understanding of how the mechanical, chemical, and adhesion properties of pollen are biologically controlled and whether strategies can be devised to manipulate pollen
