摘要

脱氧核糖核酸（DNA）具有作为廉价、功能化光子材料的潜力。以前的研究主要集中在干DNA薄膜上；然而，人们对DNA溶剂的性质和光子学应用知之甚少。本文比较了不同大小的DNA在悬浮液中的线性和非线性光学性质。特别研究了小质粒DNA、长λ DNA和超长草莓DNA。用紫外可见分光光度法评价了其线性光学性质，用闭开连续波z扫描技术研究了其非线性光学性质。此外，本文还研究了DNA悬液在长时间暴露于532 nm绿色激光下的存活能力。结果表明，经过532 nm激光照射后的DNA结构完整性和光学特性可与合成聚合物相媲美，表明DNA悬浮液可作为光子器件和光电子应用的良好光学材料。

Linear and nonlinear optical properties of DNA in suspensions

Deoxyribonucleic acid (DNA) has the potential to serve as inexpensive, functionalized photonic material. Previous research has mostly focused on dry DNA thin films; however, little is known regarding the properties and photonics applications of DNA solvents. This paper compares the linear and nonlinear optical properties of different sized DNA in suspensions. In particular, small plasmid DNA, long lambda DNA, and extra-long strawberry DNA were studied. The linear optical properties were evaluated in terms of UV–Vis spectrophotometry, and the nonlinear optical properties were investigated using the closed-open continuous wave Z-scan technique. In addition, the paper investigated DNA suspension survivability to prolonged exposure to a 532 nm green laser. The results showed DNA structural integrity after the 532 nm laser exposure and optical characteristics comparable to synthetic polymers, indicating that DNA suspensions could be a good optical material for photonic devices and optoelectronics applications.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
