Deep Subwavelength Laser-Induced Periodic Surface Structures on Silicon as a Novel Multifunctional Biosensing Platform

Yulia Borodaenko et al.

Summary: In this study, self-organized laser-induced periodic surface structures (LIPSSs) with the shortest ever reported periodicity of 70 +/- 10 nm were directly imprinted on a crystalline Si wafer upon its femtosecond-laser ablation in isopropanol. The produced deep subwavelength LIPSSs demonstrate strong anisotropic anti-reflection performance, ensuring efficient delivery of incident far-field radiation to electromagnetic hot spots localized in Si nanogaps, allowing for various optical biosensing platforms to operate. The 80-fold enhancement of spontaneous emission from organic dye molecules attached to the nanolayer, as well as in situ optical tracing of catalytic molecular transformations, support deep subwavelength Si LIPSSs as a promising inexpensive multifunctional biosensing platform.

Mechanical-electrochemical coupling structure and the application as a three-dimensional current collector for lithium metal anode

Xue Cheng et al.

Summary: A hybrid carbon nanofiber structure comprising of a gradient nitrogen doping CNF layer and a Cu doped CNF layer was successfully fabricated in this study. The Cu-decorated carbon nanofibers not only provide a deposits-free surface but also act as reinforcing rib to resist fatigue stress, delivering high Coulomb efficiency and resistance to repeat stress application.
