Agri-food safety incidents not only threaten the life and health of consumers but also
seriously hinder the development of the food supply chain. It is generally accepted that the …

Surface-enhanced Raman scattering (SERS) is one of the important techniques for sensing
applications in biological analysis, disease diagnosis, environmental science, and food …

Early diagnosis of pathogenic bacteria and treatment are essential to prevent further
infection. Photothermal therapy (PTT) is a promising sterilization method with advantages of …

Hot spots have been considered as a dominant role in surface enhancement Raman
scattering (SERS). Its generation cannot be separated from the ultra-small nanogaps, which …

We present a U-bent fiber optic SPR sensor based on the graphene/AgNPs, combined the
virtues of graphene, AgNPs and U-bent fiber. By changing the laser-induced time, we …

Wheat leaf is a natural material having abundant gaps between micro-protrusions and flat
structures. Magnetron sputtering method is used to sputter Ag film on wheat leaves and …

A stable biomimetic surface enhanced Raman scattering (SERS) system was fabricated by
covering graphene oxide (GO) on the Ag micro-islands substrate using micro/nanostructured …

Surface-enhanced vibrational spectroscopies, including surface-enhanced infrared
absorption (SEIRA) and surface-enhanced Raman scattering (SERS), selectively probe …

Field effect transistor (FET) biosensors based on low-dimensional materials have the
advantages of small in size, simple structure, fast response and high sensitivity. In this work …

In this study, we reported a novel highly ordered nano-micro hierarchical structure on
flexible polydimethylsiloxane (PDMS) layer as a SERS stamp for ultrasensitive detection …
