Effect of Ag/rGO on the Optical Properties of Plasmon-Modified SnO2 Composite and Its Application in Self-Powered UV Photodetector

“…Compared to SnO 2 , the composite films exhibited a red-shift attributed to the optical vibration caused by surface plasmon resonance (SPR) of Ag. However, due to the low concentration of Ag and graphene, the increase of absorption of Ag/rGO-SnO 2 is not prominent as it is over shadowed by more prominent SnO 2 absorption [62][63][64]. Figure 6 illustrates the optical transmittance of SnO 2 , Ag/rGO, and Ag/rGO-SnO 2 .…”

Deposition of nanomaterials: A crucial step in biosensor fabrication

“…In addition, extensive efforts have been made to use the drop-casting method to deposit nanomaterials onto a desired electrode surface for sensing applications that include H2O2 [136][137][138][139][140][141][142][143], dopamine [144][145][146][147][148][149][150][151], uric acid [148][149][150][151][152][153][154][155][156][157][158], ascorbic acid [151,[158][159][160], epinephrine [154], L-glutamic acid [155], urea [70, 161,162], HIV gene detection [163], tryptophan [164], cholesterol [165], miRNA [166,167], cysteine [168], estriol [169], ractopamine [170], lactate [171], and ochratoxin A [172]. Several research groups have reviewed nanomaterial-based nonenzymatic and enzymatic biosen...…”

Supramolecular recognition enhanced electrochemical sensing: β-cyclodextrin and Pd nanoparticle co-decorated 3D reduced graphene oxide nanocomposite-modified glassy carbon electrode for the quantification of ractopamine

“…Very recently, numerous twodimensional (2D) graphene oxide (GO)-based and reduced graphene oxide (RGO)-based materials have been utilized in electrochemical biosensors to improve their conductivity for the detection of RAC. [19][20][21] However, as far as we know, only a few works on constructing three-dimensional graphene-related sensors for RAC detection have been reported.…”
