Chemically modified starch with silicon quantum dots: Structures and properties

Abstract

Attachment of Silicon quantum dots (Si QDs) onto starch via sol-gel controlled covalent bonding to form hybrid starch particles was developed to modulate the optical, physical, and mechanical features of starch. Fabricated Si QDs chemically interacted with –OH side groups due to the sol-gel reactions on the starch molecules providing a detectable new molecular bonding to result in fluorescent emission. The produced structures formed nonlinear morphological orientations that provide a nanocomposite material platform for a facile molecular marking in daily applications.

Graphical Abstract

Fluorescent tag attachment onto the starch structures by Si quantum dots via covalent bonding was developed for the varying implications including fluorescent materials, sensors, surface coating purposes. A well designed quantum dot synthesis and starch treatment was applied to vary the optical, physical, and mechanical features of the starch particles on molecular level resulting a promising new material for visible light fluorescent material applications.
