This invention developed a novel SERS substrate based on the three-dimensional cross-structure of ultralong silver nanowires.
發展階段｜STAGE OF DEVELOPMENT
Ready to launch
- The “hotspots” in our newly developed SERS substrate are numerous and uniformly distributed on a macroscopic scale.
- As the “hotspots” in this novel SERS substrate will recombine after the contact with the probe solution, which can greatly improving the detection sensitivity.
- The diversity of the morphology and size of the silver nanowires allows a wide wavelength range of plasmon resonances, which facilitates the wide-spectrum measurement.
- SERS substrate based on the three-dimensional cross-structure of silver nanowires can be mass-produced without the use of expensive equipment, allowing the reduced price of more than 1/3 compared with the current commercialized Raman substrates.
如何解決市場痛點｜RESPONSE TO MARKET PAIN POINTS
For traditional SERS substrates composed of other shapes of plasmonic nanoparticles, the “hotspots” only exist at a few sharp corners of the nanoparticles. The increase of “hotspots” in traditional SERS substrates can only be achieved by the increase of the number of nanoparticles. However, the close packing of nanoparticles itself will cover some “hotspots”, which in turn limits the detection sensitivity. The “hotspots” in our newly developed SERS substrate are numerous and uniformly distributed on a macroscopic scale.
