In-situ growth of gold nanoparticles on electrospun flexible multilayered PVDF nanofibers for SERS sensing of molecules and bacteria

A bio-sensing surface with high biocompatibility for enhancing Raman scattering signals as enabled by a Mo–Ag film

“…5g and h). 40 In order to obtain the Raman enhancement, bacterial cells should be closely attached to the surface of the substrate during SERS detection. Conversely, the integral SERS signals of molecules could be acquired (Fig.…”

“…39 Unquestionably, these technologies make unique contributions, but novel platforms with multiple abilities are also in urgent demand. [40][41][42] By employing the Mo-Ag film, this study introduces a SERS chip, where the thin Mo-Ag film (II) was de-posited on the surface of a glass sheet (Fig. 5a), and a photograph of the chip (0.5 × 0.5 cm 2 ) is also shown.…”

Advances in Electrospun Hybrid Nanofibers for Biomedical Applications

“…Nanofibers functionalized with inorganic nanoparticles provide a combination of unique properties with a very large surface area to volume ratio. The immobilization of nanoparticles on nanofibers can be achieved by either solubilizing the nanoparticles directly in an electrospinning solution [ 140 , 141 ], reducing the precursor for nanoparticles in situ, growing them on nanofibers [ 142 , 143 ], or by electrospraying/spin coating nanoparticles on fibers’ surfaces [ 144 , 145 ].…”

3D Hot Spots Droplets on the MoS2/Al Hydrophobic Array Interface for SERS Quantitative and Multiplex Detection of Pesticide Residues

“…[33,34] The main peaks of thiram at 560 and 1386 cm −1 (Figure 5c) were indexed to the υ(S-S) and ρ(CH 3 ), respectively. [35][36][37] The major peaks of triazophos were illustrated in Figure 5d, the peak at 999 cm −1 corresponded to the benzene ring breathing, the stretching of C-N on the triazole ring contributed to the peak at 1407 cm −1 , the peak at 1600 cm −1 was derived from the C=C stretching. [38] The characteristic peaks of phosalone at 755 and 1105 cm −1 were according to the υ(benzoxazolyl), υ as (C-N-C), and υ(C-C) respectively (Figure 5e).…”
