Multifunctional nitrogen sulfur co-doped reduced graphene oxide – Ag nano hybrids (sphere, cube and wire) for nonlinear optical and SERS applications

Silver Nanowires Deposited on Cellulose Nanofibers/Graphene Oxide Hybrid Membranes as Sandwich-Structured Films for Optoelectronic and SERS Applications

“…On the other hand, tremendous studies have proved that AgNWs can be used as efficient transparent conductive devices. Nevertheless, the plasmonic noble metal nanoparticles in close collaboration with graphene or nanofiber exhibit novel properties such as optical absorption and surface-enhanced Raman scattering (SERS) which often do not belong to the isolated counterparts. , In this regard, well-designed structure by integrating of AgNWs with GO sheets could be able to efficiently advance the performances of AgNWs for plasmonic applications. Except for the GO, one-dimensional (1D) cellulose nanofibers (CNFs) with extremely high aspect ratio have emerged as a cost-effective and eco-friendly material that can be easily obtained from natural wood and bamboo to use in applications in flexible and stable papers. − The aligned CNFs exhibits abundant surface chemistry to enable functionalization in combination with other 2D materials for a range of functional materials such as stable films and nanofluidic membranes .…”

“…These outstanding characteristics make CNF/GO films as the desired candidate to offer an ideal substrate to support the large-scale AgNWs networks. Moreover, the synergistic effect between the AgNWs and CNF/GO substrate can strongly affected the plasmonic resonance of AgNWs by the dielectric property of the hybrid membrane . Therefore, taking advantage of the decoration of plasmonic AgNWs networks on the CNF/GO composite membranes, the hybrid films can be combined for integrating into flexible and conductive films to facilitate the optical absorption and SERS applications which outperform bare materials.…”

Do amino acid functionalization stratagems on carbonaceous quantum dots imply multiple applications? A comprehensive review

“…43 The functionalization process does not necessarily involve only one functional group; multiple functional groups can be co-functionalized with QDs. 44,45 The QDs possess the characteristics of all the functional groups used for functionalization, which is owing to the free reaction sites available on the functional group. The surface engineering of QDs enhances the solubility, biocompatibility, sustainability, and optical performance, such as photoluminescence, uorescence quantum yield, and photostability.…”

Modeling and Theoretical Analysis of the SERS Enhancement Factor Considering the Electronic Structural Energy

“…Surface-enhanced Raman scattering (SERS), based on the Raman effect of adsorbed molecules, is a new spectral detection technique with high efficiency, sensitivity, real time data acquisition and good specificity [1,2], and it is widely used for molecular identification and characterization, surface treatment of engineering materials, and applications in life science, food safety and other fields [3][4][5][6]. Experimental research on the preparation of SERS substrate materials has continuously advanced with the development of nanoparticle manufacturing technology [7][8][9], and one result has been more demanding requirements for theoretical SERS research.…”
