The significance of ubiquitous chirality is underscored by its applications in creating circularly polarized chiroptical materials, which are vital for optical storage, photoelectric devices, chiral sensors, and bioimaging.

Additionally, the research delved into the potential for information encryption by integrating photo-switching glycosylated molecules into bacterial cellulose matrices, thereby expanding the technological applications of these materials.

Biosynthesis, particularly through bacterial fermentation, presents an efficient and environmentally friendly method for producing stable circularly polarized luminescence (CPL)-active materials, leveraging the abundance of chiral components found in nature.

In this study, researchers utilized Komagataeibacter sucrofermentants for in situ bacterial fermentation, successfully creating fluorescent bacterial cellulose biofilms that activate CPL emission from previously silent glycosylated dyes.

This biosynthetic process significantly enhanced the CPL performance of weakly active luminophores by up to 39-fold, showcasing a remarkable amplification of chirality transfer.

The copolymerization involved covalent bonding between glycosylated luminophores and bacterial cellulose, with biodegradation studies confirming the presence of functionalized glucose and oligosaccharides.

Traditionally, the preparation of CPL materials has relied on complex chemical methods involving chiral fluorescent molecules, which can lead to unpredictable performance.

To improve CPL performance without the challenges of chemical synthesis, the study explored physical strategies such as using assemblies, metal-organic frameworks, and liquid crystals to enhance structural arrangements.
