Polycarbonate (PC) granules are widely recognized for their versatility in scientific and industrial applications, particularly in optoelectronics, environmental monitoring, and biomedical fields. In optoelectronics, the unique optical clarity and toughness of polycarbonate make it an ideal matrix for embedding fluorescent metal nanoclusters, enabling potential uses in data storage and light-emitting devices. Additionally, polycarbonate granules like these have been used in environmental studies to clarify their interaction with ecosystems, where findings suggest that both new and aged polycarbonate can influence plant germination and growth rates, offering insights into microplastic pollution. In biomedical research, polycarbonate’s biocompatibility and structural integrity support applications in medical devices and tissue engineering scaffolds. These diverse capabilities position these polycarbonate granules as a material of choice for researchers and innovators across disciplines.
