Synergistic effect of Bi-doped exfoliated MoS₂ nanosheets on their bactericidal and dye degradation potential

Abstract

Nanosheets incorporated with biological reducing agents are widely used to minimize the toxic effects of chemicals.

Photocatalytic, Bactericidal and Molecular Docking Analysis of Annealed Tin Oxide Nanostructures

“…Significant zones of inhibition recorded for SnO (250, 500 and 750 °C) samples for E. coli and S. aureus ranged Size, concentration and morphology of nanostructures directly affects oxidative stress produced. Antibacterial activity imperiling size and concentration portrays inverse relation to size [68][69][70]. Nanostructures more efficiently produce reactive oxygen species (ROS) which exist in bacterial membrane resulting cellular organelles extrusion and bacteria death [71].…”

Ultrasensitive SERS Detection of Cancer‐Related miRNA‐182 by MXene/MoS2@AuNPs with Controllable Morphology and Optimized Self‐Internal Standards

“…As the HAuCl 4 concentration increases, AuNPs become aggregated and unevenly distributed, resulting in fewer “hot spots” (Figures S4 and S5, Supporting Information). In addition, the UV–vis spectra obtained from different substrates (Figure S6, Supporting Information), the distinct absorption peaks at 340 nm (for MXene), [ 27 ] 230 nm (for MoS 2 ), [ 36 ] and 525 nm (for AuNPs) also indicates the successful preparation of MMA, while the red‐shift and broadening of UV band from 515 to 545 nm caused by enhanced plasmon resonance absorption of ultraviolet and visible light can further confirm AuNPs size increasing.

[37] In the schematic diagram of AuNPs (yellow particles) controllable growth (Figure 3a), as the HAuCl 4 concentration increases, the seeds of AuNPs first tend to contact and then grow on the edge of MoS 2 (purple slices) through AuS bond, which is due to that the MoS 2 nanosheets vertically adhere to the flat surface of MXene (green substrate), and its edge provides excellent sites for precise control of particle size and gap.…”

Electrochemical Exfoliation of 2D Advanced Carbon Derivatives

“…Two-dimensional (2D) materials motivated scientific society owing to inspired decisive passion in electrical, mechanical, and optical disciplines, showing extraordinary properties comparatively layered bulky counterpart. 2D pioneer carbon material, graphene, previously presented advanced studies in the fields, particularly, [1] membranes, [2] bio-sensors, [3] energy storage technologies, [4,5] and topographic spintronics devices, [6] despite last decade advancement in graphene literature approach, still alarming goal from its targets, as is the condensed matter physics, [7,8] towards the aforesaid trend, a series of ultrathin materials were isolated via exfoliation process, as synthesized incorporating metal chalcogenides, [9,10] double-layered-hydroxide, [11] boron nitride, [12] preliminary investigation regarding 2D nano-materials was attractively oriented by fundamental research approaches inheriting novelty properties, new channels have certainly opened and encouraged recently towards high application inspired studies [13,14]. Evidently, 2D materials frequently contributed active counterpart as a promising one in functional devices and versatile electronics.…”
