Raman spectrum provides a direct molecular fingerprint. According to the characteristics of functional groups in the components, the detector shows a characteristic peak spectrum which is a fingerprint to identify chemical components in the substrate. Phansco has developed the most cost-effective "Surface Enhanced Raman Scattering (SERS)" in the world. Phan2 SERS substrate has no fluorescent background. The SERS chip uses the nano-structured solid-state enhanced substrates to produce surface plasmon resonance (SPR) with the chemical molecules. The SPR greatly enhances the magnification and structure uniformity, and enhances the signal to 10-million times, and the detection limit could succeed from ppm to ppb for chemical residue.
Phan2 SERS substrate is made by the oblique angle deposition method (PVD technology) which Phansco developed. The method can produce the structure of the SERS substrate effectively. The core technology of SERS substrate structure has obtained the Taiwan patent (TW No. I490474) and theUnited States Patent (US No. 8,898,811).The oblique angle deposition method is known as Glancing Angle Deposition (GLAD) technology.The pores of the metal film are mainly caused by the special physical structure of the substrate carrier, which is called the self-shielding effect.
Phan2 SERS substrate is suitable for wide wavelength laser excitation range (532 nm, 633 nm, 785 nm and 1064 nm), the silver nanopillar structure made by GLAD enhanced Raman spectral signal intensity of 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 drug safety.
