There are significant advantages in the development of flexible laser materials based on organic and biological materials, which could have wide-ranging applications including those in wearable sensors. This project applies a fundamental approach to advantage of the inherit polarization properties of cellulose nanocrystals (CNC) to create new lasing materials. The challenges investigators address are the toxicity, water solubility and stability of organic materials. To address these barriers, they will explore the properties of a diverse classes of materials.The PI provides good evidence that CNC films have left-handed circular dichroism that can be enhanced and modified by inclusion of polymers, which can further increase the strength and flexibility of the films. To produce lasing materials, the PIs plan to incorporate quantum dots (QDs) into the films.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

基于有机和生物材料的柔性激光材料具有显著的优势，可以在包括可穿戴传感器在内的各种领域中得到广泛的应用。本计画利用纤维素奈米晶体（CNC）固有的偏振特性，创造新的雷射材料。研究人员面临的挑战是有机材料的毒性、水溶性和稳定性。为了解决这些障碍，他们将探索不同种类材料的特性。PI提供了很好的证据，证明CNC薄膜具有左手圆二色性，可以通过包含聚合物来增强和修改，这可以进一步增加薄膜的强度和柔韧性。为了生产激光材料，PI计划将量子点（QD）纳入薄膜中。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
