Abstract Mental stress is a dangerous factor for the health of living beings, which can lead to various diseases. However, currently, there lack diagnostic tools that quickly and accurately quantify levels mental stress. Cortisol an important hormone widely present in bodily fluids; its concentration reflect level organisms. Here, we report surface-enhanced Raman spectroscopy (SERS) probe based on flower-like graphene oxide-molybdenum disulfide composite material functionalized with cortisol DNA recognition element tetracyanoquinodimethane label, remarkable enhancement value 7.38 × 10 5 , exhibits excellent detection ability wide range concentrations from 1 nM 000 nM, limit down 0.773 nM. The whole takes only 20 min. In addition, SERS selectively detect other substances similar chemical structures, makes applicable complex biological systems good reproducibility stability. This designed has been successfully employed mouse serum cortisol, high accuracy compared enzyme-linked immunosorbent assay (ELISA) results, demonstrating great potential actual sample detection.

The focused vortex beam generates a hollow beam, which has been widely used for size-controlled nanoparticle formation on various materials. However, the size variation of is limited by integral order 2π phase wrap, while waste caused large side lobe around center. In this study, we propose method generation splitting femtosecond laser and imparting opposite phases to outer annular region central Gaussian region. After focusing, these two regions overlap at focal spot, resulting in due cancellation. By modulating relative dimensions regions, center can be continuously varied. When such surface processing, thermal capillary effect facilitates convergence molten material toward center, ultimately leading nanoparticles. This ability control allows precise with diameter range from 140 nm 940 nm. holds great promise guiding research into properties that are influenced effects.
