Microwave-assisted rapid synthesis of honeycomb core-ZnO tetrapods nanocomposites for excellent photocatalytic activity against different organic dyes

Synthesis, Characterization, and Assessment of Anti-Cancer Potential of ZnO Nanoparticles in an In Vitro Model of Breast Cancer

“…It was considered that the repeated use of chemical methods contributes to the appearance on the surface of nanoparticles of certain toxic chemicals that could have a harmful impact in medical applications [ 28 ]. Sol-gel processing [ 29 ], homogeneous precipitation [ 30 ], mechanical milling [ 31 ], organometallic synthesis [ 32 ], the microwave approach [ 33 ], spray pyrolysis [ 34 ], thermal evaporation [ 35 ], and mechanochemical synthesis [ 36 ] are all strategies for producing ZnO NPs. Chemical methodologies and hazardous reducing chemicals, the majority of which are very reactive and harmful to the environment, are often used in these procedures [ 37 ].…”

Synergistic effect of modified pore and heterojunction of MOF-derived α-Fe2O3/ZnO for superior photocatalytic degradation of methylene blue

“…The E g value of ZnO generated using template method is not much different from the E g value of ZnO generated by other methods. 8,40,51 Meanwhile, Fe(50)ZnO showed an increasing E g value when compared to the other photocatalysts. This condition indicates that the optimum addition of α-Fe 2 O 3 is 25%.…”

Advanced metal and carbon nanostructures for medical, drug delivery and bio-imaging applications

“…In the beginning, a few layers of graphene were gently exfoliated from graphite, demonstrating enormous potential in the disciplines of materials engineering, physics, chemical, biology, and many others. [103][104][105][106][107] Following other types of carbon nanocrystal, such as fullerene (which would be formed by trying to wrap 2D graphene into a 0D molecule, Fig. 8b), carbon nanotubes (CNTs, formed by cylindrically rolling 2D graphene layers into 1D nanotubes, Fig.…”

“…112 It also has some superior mechanical strength (nearly 200 times stronger than steel) and other characteristics (Young's modulus ≈1100 GPa), ultra-thin nanostructure (10 6 times thinner than a human hair), very high surface area (≈2630 m 2 g −1 ), superior heat conductivity (≈5000 W m −1 K −1 ), high stretchability, full flexibility but high insulative properties, inherent biocompatibility, and chemical inertness. [103][104][105][106][107] Furthermore, the latest advancements in new materials, cost-effectiveness, and scalable manufacturing technologies have enabled it to become one of the most appealing nanomaterials in different fields such as microelectronics, composites, alternative energy, sensor systems, and catalysts supports. [113][114][115] Due to these aforementioned characteristics, and its biocompatibility, functionalized graphene has been applied in chemical and biological applications, [116][117][118] a few of which include biosensing, antibacterial/antiviral interaction, anti-cancer interaction, photothermal treatment therapy (PTT), targeted pharmaceutical administration, electrical stimulation of cells, and tissue culture.…”
