“…Besides, AgNPs are known as a high potential candidate to modify electrode surfaces for direct detection of organic pollutants. 23,24 Many reports demonstrated that the significant increase in active surface area and conductivity of the electrode modified with AgNPs was recorded, which is considered due to their promising electronic, chemical, and electrochemical properties. Hence, AgNP-based electrochemical sensors exhibited sufficient sensitivity and selectivity.…”

We have introduced potential modifiers synthesized from attached Ag nanoparticles (NPs) on MnO2 nanostructural surfaces, and fabricated an electrochemical sensor toward 4-nitrophenol (4-NP) detection. MnO2 with various morphologies (nanowires, nanorods, and nanosheets) has been prepared by hydrothermal and microwave-assisted hydrothermal methods, while AgNPs have been prepared by the simple electrochemical method. The structural characteristics and surface morphologies have been investigated via X-ray diffraction and scanning electron microscopy measurements. The effect of the change in morphology on the electrochemical behaviors and sensing performance has been investigated and discussed in detail. A parameter series involving the redox reaction of [Fe(CN)6]3-/4- and 4-NP reduction process has been calculated for each as-prepared modified electrode. Electrochemical results evidenced that benefiting from possessing outstanding electrochemical behaviors such as better conductivity, faster electron transfer ability, larger electroactive surface area, and higher charge transfer kinetics, MnO2 sheets-Ag/SPE has offered wider linear concentration range of 0.5-50 μM, LOD value as low as 0.073 µM, and high selectivity/repeatability. Furthermore, the optimization in the morphological aspect of MnO2 nanosheets and synergic effects arising from the effective combination with AgNPs make it become a model material for modifying electrode surfaces, indicating great potential for advanced electrochemical sensing applications.

“…In the last few years, numerous reviews concerning the biosynthesis of metal-containing NPs were published [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47], many specialising in either one or two types of NPs [48][49][50][51][52][53][54][55][56] or biosynthesis for special applications [57][58][59][60][61][62][63][64][65]. Among these reviews, several specialised in fungal biosynthesis-the mycosynthesis of NPs [15,26,27,[66][67][68][69][70][71].…”

In the 21st century, nanomaterials play an increasingly important role in our lives with applications in many sectors, including agriculture, biomedicine, and biosensors. Over the last two decades, extensive research has been conducted to find ways to synthesise nanoparticles (NPs) via mediation with fungi or fungal extracts. Mycosynthesis can potentially be an energy-efficient, highly adjustable, environmentally benign alternative to conventional physico-chemical procedures. This review investigates the role of metal toxicity in fungi on cell growth and biochemical levels, and how their strategies of resistance, i.e., metal chelation, biomineral formation, biosorption, bioaccumulation, compartmentalisation, and efflux of metals from cells, contribute to the synthesis of metal-containing NPs used in different applications, e.g., biomedical, antimicrobial, catalytic, biosensing, and precision agriculture. The role of different synthesis conditions, including that of fungal biomolecules serving as nucleation centres or templates for NP synthesis, reducing agents, or capping agents in the synthesis process, is also discussed. The authors believe that future studies need to focus on the mechanism of NP synthesis, as well as on the influence of such conditions as pH, temperature, biomass, the concentration of the precursors, and volume of the fungal extracts on the efficiency of the mycosynthesis of NPs.
