“…Interestingly, NP-GO NCs exhibit enhanced surface enhanced Raman scattering, catalytic, and antibacterial properties compared to bare GO and NP. [208][209][210][211][212][213] Recent studies reported the fabrication of AgNPs-decorated GO as an effective antibacterial agent. [213][214][215][216] Synthesis of AgNPs decorated on magnetic GO NCs was demonstrated, which showed highly effective inhibitory property and reusability even at the very low concentration (12.5 ppm).…”

Silver nanotechnology has received tremendous attention in recent years, owing to its wide range of applications in various fields and its intrinsic therapeutic properties. In this review, an attempt is made to critically evaluate the chemical, physical, and biological synthesis of silver nanoparticles (AgNPs) as well as their efficacy in the field of theranostics including microbiology and parasitology. Moreover, an outlook is also provided regarding the performance of AgNPs against different biological systems such as bacteria, fungi, viruses, and parasites (leishmanial and malarial parasites) in curing certain fatal human diseases, with a special focus on cancer. The mechanism of action of AgNPs in different biological systems still remains enigmatic. Here, due to limited available literature, we only focused on AgNPs mechanism in biological systems including human (wound healing and apoptosis), bacteria, and viruses which may open new windows for future research to ensure the versatile application of AgNPs in cosmetics, electronics, and medical fields.

“…[6][7][8] Furthermore, the chemical reactivity of 2D materials such as graphene oxide (GO) and TMDs has raised concerns and novel templates have been proposed to fabricate functional composites. [9][10][11][12][13][14][15][16][17] Black phosphorus (BP) has emerged to be an exciting member of the 2D family. 18,19 BP has strong in-plane bonds in conjunction with weak van der Waals interlayer interactions thereby enabling exfoliation into few-layer BP sheets or phosphorene (single-layer BP).…”

The reducing capability of two-dimensional black phosphorus is demonstrated. The high reducing ability and unique twodimensional morphology of black phosphorus not only facilitate in situ synthesis of Au nanoparticles and BP@Au composites, but also enable multiscale control of local reduction of GO to reduced GO (rGO). The novel two-dimensional reductant has large potential in various in situ nanofabrication applications. 1, 2 For instance, graphene boasting good optoelectronic characteristics and high mechanical strength has large potential in energy conversion and storage 3-5 and transition-metal dichalcogenides (TMDs) with unique semiconducting properties are attractive to scalable digital field-effect transistors.6-8 Furthermore, the chemical reactivity of 2D materials such as graphene oxide (GO) and TMDs has raised concerns and novel templates have been proposed to fabricate functional composites.

Comparison of Graphene Oxide and Reduced Graphene Oxide for DNA Adsorption and Sensing

et al. 2016

Fluorescently labeled DNA adsorbed on graphene oxide (GO) is a well-established sensing platform for detecting a diverse range of analytes. GO is a loosely defined material and its oxygen content may vary depending on the condition of preparation. Sometimes, a further reduction step is intentionally performed to decrease the oxygen content and the resulting material is called reduced GO (rGO). In this work, DNA adsorption and desorption from GO and rGO is systematically compared. Under the same salt concentration, DNA adsorbs slightly faster with a 2.6-fold higher capacity on rGO. At the same time, adsorbed DNA on rGO is more resistant to desorption induced by temperature, pH, urea, and organic solvents. Various lengths and sequences of DNA probes have been tested. When its complementary DNA (cDNA) is added as a model target analyte, the rGO sample has a higher signal-to-background and signalto-noise ratio, while the GO sample has a slightly higher absolute signal increase and faster signaling kinetics. Adsorbed DNAs on GO or rGO are still susceptible to non-specific displacement by other DNA and proteins. Overall, while rGO adsorb DNA more tightly, it allows efficient DNA sensing with an extremely low background signal.
