Phansco owns a unique patent in SERS chip which is cooperated with NTUT’s Prof. Ren lab and a cost-effective solution in production capacity. Phansco succeeded to make out the very uniform nano-structure SERS chip with high performance by its own Glancing Angle Deposition, GLAD, technology. The SERS chip can produce a surface plasmon resonance (SPR), and enhance the signal to 10-million times, and the detection limit could succeed from ppm to ppb for chemical residue. The stable nano-structure chip can provide a useful application in food safety inspection.
Phan2 SERS Substrate is suitable for various laser excitation wavelength (532 nm, 633 nm, 785 nm and 1064 nm), the silver nanopillar structure made by GLAD enhanced Raman spectral signal intensity by millions to tens of millions of times with high surface structure uniformity and good Raman signal repeatability. It can stably detect trace substances, improve spectral signal intensity and analysis. It is an advanced technology for rapid detection of food and pesticide residues.
Dithiocarbamates-specific Phan2 SERS substrate is suitable for the semiquantitative dithiocarbamate analysis method in vegetables and fruits. The process can be finished in 10 minutes. The pharmaceutical products include: Thiram, Ferbam, Propineb, Mancozeb, Maneb, and Metiram. The compound structure belongs to three categories.
