TīmeklisAn accuracy improved ratiometric SERS sensor for rhodamine 6G in chili powder using a metal–organic framework support ... In this work, a homemade portable Raman device was used for SERS detection, which included a semiconductor CW laser operating at 785 nm (Laser 785-5HF, Oceanhood, Shanghai) with controllable power over the … TīmeklisTo evaluate the SERS performance of the as-synthesized paper-based substrate, Rhodamine 6G was used as Raman probe. Control paper (for normal Raman scattering) and as-synthesized GNP coated paper (for surface-enhanced Raman scattering) substrates were both loaded with 2.5 μL of Rhodamine 6G at 1 μM …

Tīmeklis2024. gada 30. jūn. · An excellent SERS detection behavior was obtained on the PQD–G/Au composite for rhodamine 6G (R6G) and p-nitrophenol (PNP) with a large linear detection range (10 −12 to 10 −6 M for R6G and 10 −8 to 10 −4 M for PNP) and a low detection limit (6.02 × 10 −13 M for R6G and 2.95 × 10 −9 M for PNP). The … TīmeklisEncouragingly, based on this strategy, the SERS intensity of cation-type dye of model probe molecules of Rhodamine 6G (R6G) with 2 × 10-6 M in preparation can be increased by more than 20-fold of magnitude, as compared with that of R6G adsorbed on the already-prepared SERS-active substrates by using a general procedure for … scooter board with handles

The R6G has a formula of C 28 H 31 N 2 O 3 Cl with a molecular weight of 479.01. The Au-HA-CNT substrate was incubated in 5 ml of R6G 10 −6 M solution for 24 h to realize an even … TīmeklisAbstract The dependence of the Surface Enhanced Raman Scattering (SERS) by gold nanoparticles on their shape is examined using the organic dye, rhodamine 6G (R6G) as probe molecule. SERS has been explored extensively for applications in sensing and imaging, but the design and optimisation of efficient substrates is still challenging. preaction fire
