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.

开发基于有机和生物材料的柔性激光材料具有显着的优势，可具有广泛的应用，包括可穿戴传感器。该项目采用一种基本方法，利用纤维素纳米晶体 (CNC) 继承的偏振特性来创建新的激光材料。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，他们将探索不同类别材料的特性。PI 提供了充分的证据，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，从而进一步提高强度和柔韧性的电影。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智力优点和更广泛的影响审查标准进行评估，认为值得支持。
