Wet-spun Ag/PEDOT: PSS composite fibers for high-sensitive SERS sensing and high electrical conducting.

Nanometal-based composite fibers have been widely explored in flexible sensors due to their outstanding optical and electrical properties. However, the weak binding force between metallic nanomaterial and fiber greatly limits the real application. In this work, nano silver (Ag) are strongly bonded with poly(3,4-ethylenedioxythiophene)-poly (styrene sulfonate) (PEDOT: PSS) fiber by the wet-spun process.

Multidomain Oriented Particle Chains Based on Spatial Electric Field and Their Optical Application.

The manipulation technology of particles is significant in drug screening, disease detection and treatment, etc. Here, we reported the multidomain oriented particle chains based on a spatial electric field and their optical application. According to the differences in the dielectric behavior of particles, the preparation of multidomain oriented particle chains in the gel was successfully realized by using the dielectrophoretic force and electroosmotic rotation.
