Hydroxypropyl Cellulose Assembled Microspheres as Structural Color Barcodes from Revolving Microfluidics.

ABSTRACT: Optical barcodes are versatile information carriers widely applied for encryption, commercial anti-counterfeiting, and biomedical fields. Hydroxypropyl cellulose (HPC), as a natural derivative, exhibits excellent biocompatibility and can self-assemble into cholesteric liquid crystals (CLCs) with structure color. However, the high viscosity of HPC CLCs is a huge hurdle for material processing and thus limits their applications. In this study, a high-speed revolving microfluidic platform is developed for emulsifying high-viscosity methacrylate functionalized HPC (HPC-MA) solution to form droplets. HPC-MA molecules in the droplets can self-assemble into CLCs by water evaporation, and the resultant CLCs droplets can be cross-linked to form structural color barcode particles. The prepared HPC-M
