SERS CHIP 3D-RCW
Crossed-Wire SERS chip
PTT launches a 3D nanostructures sers chip, Silver nanowire 3D random crossed-wire woodpile (3D-RCW) nanostructures were designed and prepared. The 3D-RCW provides rich “antenna” and “hot spot” effects that are responsive for surface-enhanced Raman scattering (SERS) effects and plasmon-enhanced fluorescence (PEF). The RCW is very sensitive nanochip capable of emission and Raman-enhanced detections uses micro levels of analysis volumes. Consequently, and SERS of pesticides (thiram, carbaryl, paraquat, fipronil) were successfully measured and characterized, and their detection limits were within 5 μM~0.05 µM in 20 µL.
3D-RCW SERS chip is a very sensitive substrate, one drop of sample is enough to collect Raman spectrum. Users don’t need to add samples drop-wisely and repeatedly to get stronger and clearer SERS.
